Версия А

ПРЯМОУГОЛЬНЫЙ ДВУХФАЗНЫЙ
ДЕФИБРИЛЛЯЦИОННЫЙ ИМПУЛЬС
Общая информация

Введение

Существуют дефибрилляторы M Series

®

с усовершенствованной электрической конструкцией, обеспечивающей

уникальную бифазную форму импульса дефибрилляции и кардиоверсии. В этой опции электроэнергия
дефибриллятора передается в двух последовательных фазах тока (напряжения) противоположной полярности. Этот
тип формы волны дефибриллятора обычно называется «бифазным» в противопоставление более ранней
«монофазной» демпфированной синусоидальной волне, присущей для большинства имеющихся в продаже
дефибрилляторов.

Прямолинейный бифазный импульс дефибриллятора ZOLL M Series имеет уникальные характеристики,
предназначенные для получения оптимальных клинических результатов и проверенные в многоцентровых
клинических испытаниях. Клинические испытания продемонстрировали, что эта форма дефибрилляционного
импульса клинически эффективна как для дефибрилляции, так и для синхронизированной кардиоверсии.

В настоящем вкладыше объясняется, чем прямоугольный бифазный импульс дефибриллятора M Series отличается
от монофазного импульса в виде демпфированной синусоиды других приборов M Series. Его следует использовать
совместно с руководством по эксплуатации для дефибрилляторов M Series. Важная информация по технике
безопасности, относящаяся к общему использованию M Series, дается в разделе «Рекомендации по технике
безопасности» руководства по эксплуатации дефибрилляторов M Series.

Показания к применению M Series с прямолинейным бифазным импульсом

Приборами ZOLL M Series с бифазным импульсом должен пользоваться только квалифицированный медицинский
персонал для проведения преобразования жизнеугрожающих аритмий: вентикулярной фибрилляции (VF) и/или
вентикулярной тахикардии (VT), в нормальный синусовый ритм или другие сердечные ритмы, обеспечивающие
гемодинамическую стабильность.
Кроме того, этот прибор должен использоваться в синхронизированном режиме только квалифицированным
медицинским персоналом для устранения фибрилляции предсердий (AF) на более низких значениях дозы энергии и
силы тока, чем у монофазных дефибрилляторов. Квалифицированный врач должен решить самостоятельно, когда
необходима синхронизированная кардиоверсия.
Этот прибор также должен использоваться в синхронизированном режиме только квалифицированным медицинским
персоналом для электроимпульсной терапии вентикулярной тахикардии (VT). Квалифицированный врач должен
решить, когда необходима синхронизированная кардиоверсия.
Прямолинейный бифазный импульс (RBW) прошел успешную проверку в многоцентровых рандомизированных
клинических испытаниях эффективности трансторакальной дефибрилляции VT/VF и AF, которые подтвердили
возможность и эффективность проведения бифазной дефибрилляции и кардиоверсии у взрослых пациентов при
более низких значениях дозы энергии и силы тока, чем у существующих монофазных приборов. Бифазный импульс
M Series имеет широкий диапазон доз энергии, выбираемых пользователем, включая более низкие значения
энергии, чем те, которые были использованы во время клинических испытаний.
Автоматический (АНД) и консультативный режимы дефибрилляции следует использовать только при
подтвержденном диагнозе фибрилляции желудочков у пациентов со следующими симптомами:

пациент должен быть без сознания.

у пациента должна быть остановка дыхания (не дышит).

у пациента должен отсутствовать пульс.

ВНИМАНИЕ

Нельзя использовать автоматический режим для пациентов младше
8 лет (В соответствии с Рекомендациями АНА по сердечно-легочной
реанимации взрослых и автоматической дефибрилляции 3-5, 1998 г.)

Analyzer (software 1.06 or higher) with optional external plug in pacing module (TQA-17) or equivalent.

Note: The following tests are to be performed only on M Series units equipped with the optional pacing function.

The pacer output can be measured using an oscilloscope set to DC coupling connected across a load resistor. (See diagram in column for universal cable connector polarity.) The load resistor is a 100 ohm, 5 watt or greater. The pacer output is a positive going pulse, 40 +/- 2 ms duration with an amplitude of 0.1 volt per milliamp of selected output

(e.g., 40 milliamps of selected output has an amplitude of 4 +/- 0.5 volts the specified tolerance displayed on the oscilloscope).

If an external non-invasive pacer analyzer is being used, then follow the manufacturer’s guidelines for measuring the frequency (ppm), output (mA) and the pulse width measured in milliseconds. Note that the analyzer pace load resistor must be less than 250 ohms.

M Series Service Manual

Reported Problem Recommended User Action Recommended Technical Action

Flash or arcing under defibrillator pad.

Displayed HR not accurate.

No artifact present.

•

Avoiding using alcohol and betadine in and around the treatment area because these skin preparations may lead to increased conductivity and/or bonding between the electrode’s adhesive and skin.

•

Check for gel droop. If the gel has leaked out of the gel treatment area, replace the electrode.

•

Ensure pads are coupling to the patient’s skin and connected to the universal cable.

•

Check for dried out gel on the defibrillator pad.

•

Clip patient’s excessive hair. Do not shave hair.

•

Check expiration date. Replace pad if date has expired.

•

Do not conduct chest compression through the pads because the pads could be damaged leading to the possibility of arcing and skin burns.

•

Apply the back electrode first. If the front electrode is already in place when the patient is being maneuvered for placement on the back, the front may become partially lifted, possibly causing arching and skin burns.

Verify heart rate flashes with each QRS on display.

•

Change lead selection.

•

Change ECG size.

•

Reposition ECG electrodes.

•

Ensure that wet gel pads are stored flat.

ECG Front End

The ECG front end provides an electrically isolated serial interface between the main system board functions and patient interface ECG connectors. It performs the following:

• Analog ECG amplification and signal conditioning.

• Pacemaker pulse detection.

• ECG signals acquisition and analog to digital conversion.

• ECG 3/5/12-lead detection.

• ECG leads off detection.

• Front-end defibrillator protection.

• Isolated power conditioning.

• Patient impedance measurement via MFE or paddles.

Multifunction Electrode (MFE)/PADS (System Board and High

Voltage Module)

Selected for optimal performance for the application, a dedicated ECG amplifier with a limited bandwidth processes the signal. It is then chopper modulated and coupled to the system side via an isolation transformer. On the system side, the signal is synchronously demodulated, converted by a 10 bit A/D at 250 samples per second and digitally processed by the main control unit of the system board.

To measure thoracic impedance, a high frequency (HF) measuring current passes through the patient’s chest and measures the resulting voltage across the electrodes. After amplification, the impedance signal is synchronously demodulated. It is then converted to a stream of pulses with frequency proportional to the measured impedance.

CPU and EPU

The Main System Board contains two microprocessors. A Motorola HC-11 single chip microprocessor is used to acquire, convert and process ECG signals, (ECU). An Hitachi SH-3 RISC microprocessor acts as the system’s main

CPU. The SH-3 CPU and has an integrated on-chip multiplier, a cache memory, a memory management unit as well

105

M Series Service Manual as data protection and virtual memory functions. It also has a timer, a real time clock, an interrupt controller, a serial communication interface (SCI), and other peripheral functions necessary for the system operation. The memory circuitry includes Flash ROM, internal flash non-volatile memory and DRAM.

The EPU acquires ECG data and runs the A/D convertor that sends data in the form of a serial stream to the CPU.

High Voltage Module

The High Voltage (HV) module includes the high voltage circuitry required for pacing and defibrillation, including the defib charge circuitry, solid state patient relay, safety relay, defib capacitor, defib choke and front end protection circuitry for the MFC ECG. There are two different types of HV Modules: a damped sinusoidal waveform HV module and a Biphasic (HV) module.

Charging

M Series Service Manual

Defibrillator Charging and Discharging

The defibrillator charges and discharges high voltage capacitor energy. A user can initiate a charge in three ways by

1) pressing the charge button on the front panel; or (2) pressing the charge button on the paddles; or (3) configuring unit to charge automatically when it detects a shockable rhythm following an ECG analysis. To initiate a discharge, a user depresses both shock buttons on the paddles or depresses a single shock button on the front panel.

The defibrillator circuit charges the high voltage capacitor to the energy level the user specifies.This circuit also provides feedback to the main system board on the high voltage capacitor’s voltage level and discharges the high voltage capacitor energy through paddles or the universal cable. The defibrillator portion of the high voltage circuitry is active only when the front panel selector switch is set to DEFIB.

The charging process starts when the Main System Board detects a charge request. The defibrillator circuits begin charging the high voltage capacitor to the target voltage or energy that the user selects on the front panel display. The

Main System Board continuously monitors the capacitor voltage signal to ensure that the high voltage capacitor charges at the proper rate. When the target voltage is reached, the Main System Board initiates a continuous beeper tone to indicate that defibrillator is ready to discharge. The target energy level displays on the display screen.

The defibrillator holds the energy for 60 seconds for manual units and 15 seconds for AED units, refreshing the energy level as necessary. An intermittent beep tone sounds during the last ten seconds (five seconds for AED unit) of the hold period. After the 60 second period, if the defibrillator has not been discharged, the energy is dissipated into the internal discharge resistor by closing the safety relay (XSAFREL). The unit discharges internally and displays a warning message if it is not functioning properly.

Unlike previous ZOLL designs that isolated the patient from defib circuitry via an electromechanical patient relay, the

M Series utilizes a bank of silicon-controlled rectifiers (SCRs). As the defibrillator capacitor is charged, the voltage is monitored via R1 — R4, which drive differential amplifiers referred to the system ground. These resistor dividers split the capacitor voltage more or less equally above and below ground in order that the positive capacitor terminal is approximately 2500 volts above ground, and the negative capacitor terminal is approximately 2500 volts below ground

(at 360J setting). The voltage at the patient electrodes is set by the divider RN1 and RN2. These networks are each 5X

25 M (125 M total) whose total resistance is specified to be 125 M +- 1%. As a result, the patient is nominally at ground and the hot switch bank is split into a ‘positive’ side and a ‘negative’ side.

107

M Series Service Manual

Discharging

Initiating a discharge provides voltage to the solid state patient relay and notification to the Main System Board through the PADMON signal. The Main System Board then controls activation of the solid state patient relay (for

DSW only). Energy delivered to the patient goes through a wave shaping inductor to create a defibrillation waveform compliant with AAMI Standards. When the patient discharge SCRs are deactivated, the safety relay closes to internally dissipate any remaining energy.

If the M Series is in the self test mode, the energy is delivered internally. The microprocessor calculates the actual delivered energy from the current waveform and displays a TEST OK message on the display, if the self test meets the appropriate criteria. If the criteria are not met, a TEST FAILED message displays.

High Voltage Capacitor Monitor

Before charging the defibrillator, the High Voltage Capacitor monitor runs a self test to check the pace relay. The pace relay controls the high voltage circuitry configuration either for generating pace pulses or for charging the high voltage defibrillation capacitor.

The defibrillator capacitor is shunted for safety reasons with a resistor and relay to internally dissipate any energy remaining. When the Main System Board initiates a charge, this relay opens by providing a low level on signal

XSAFREL. The safety relay is a biased reed switch. The relay is driven by Q318.

The pace relay driver is a grounded source switch Q308 that is biased on by R593. It is held off by Q330 when

XPACEREL is ‘1’ false. When XPACEREL comes true, Q330 is turned off, and Q308 is no longer clamped off.

The high voltage capacitor is charged by converting the system battery voltage to a pulsed high voltage by way of transformer T1. The basic operating frequency signal that is used to switch transistor Q1 providing current in the primary windings of the transformer T1 originates in the system board’s gate array.

When the high voltage capacitor is charging, the Main System Board independently monitors the capacitor voltage through signal VMON. If the Main System Board detects an improper level, it halts operation by setting SAFE high.

This disables the SCR discharge circuitry and flyback transformer drive.

The solid state patient relay discharges via the signal PATREL_DRV generated by XPATREL and Q304, Q323, and

Q322. PATREL_DRV is disabled when XPACE_SEL is at a logic low.

When the solid state patient relay activation completes, the Main System Board releases the XPATREL signal. Several hundred milliseconds later, the safety relay closes to ensure the high voltage capacitor energy is completely dissipated.

108

M Series Service Manual

The Pacer circuit produces and delivers user-controllable pace pulses to the pacing electrodes. To initiate pacing, the front panel switch is turned to PACER and the OUTPUT and RATE controls are set. Pacing current amplitude is constant during the pulse and is determined by the position of the front panel PACER OUTPUT dial. Pacing pulse rate is determined by the position of the front panel PACER RATE dial. The pacing pulse duration is fixed at 40 milliseconds.

Pacer/Defibrillator Control Signals

The Pacer/Defibrillator Control charges the high voltage capacitor to a voltage requested by the main system board in response to user energy selections. It delivers defibrillator energy to the patient through the patient connector to the paddles and pacer electrodes or multi-function electrodes (PADS). This control also generates pacing pulses at rates and amplitudes requested by the main system board in response to user selections, controls damped sinusoidal waveform and biphasic waveform defibrillation, and measures pace current and high voltage capacitor voltage by two independent channels.

Internal Discharge Resistor Module

The Internal Discharge Resistor Module contains the internal discharge resistor, and a means for dissipating the heat generated by the internal discharge.

AC/DC Charger Module

The AC/DC Power/Battery Charger provides a universal (IEC 320) connection to the AC mains or to a DC source, input line filtering and double-pole fusing (for a mains input), AC-DC and DC-DC conversion and isolation barrier between the M Series and power sources. This module also provides the power necessary to run the M Series in any mode of operation, as well as providing additional charging current to the battery. When the M Series is turned off but connected to an external AC or DC source, the charger module controls battery charging currents and voltages needed to charge the M Series battery. These voltages and currents are controlled in response to the main CPU signals that manage the battery charging process.

System Interconnect Module

The system interconnect PWBA receives signals from the Main System Board and in turn controls operation of the stripchart recorder and PCMCIA functions.

111

M Series Service Manual

Stripchart Recorder

The Stripchart Recorder module includes a microprocessor, serial interface to the main system board and circuitry which drive the stripchart recorder’s motor and printhead in response to the main CPU signals. Based upon signals sent by the main CPU, the recorder’s main processor drives the recorder stripchart motor, formats data for printing on the chart and drives the printhead. It also detects when the sensor drawer is not properly fitted into the unit, when the paper supply is out and needs to be refilled and the print head temperature.

PCMCIA Slots

The PCMCIA interface module supports two PCMCIA slots which accept Type I and/or Type II PCMCIA cards.

These cards may be read or written to. Data sent by the main CPU is passed to the installed PCMCIA card via the system interconnect PWBA.

Front Panel and Controls PWBA

User Interface Module provides several functions that enable the user to operate the unit. The user interface has a display monitor and three rotary selector switches. One selector switch is for three modes: pacer, monitor and defibrillation. The two other knobs are for pacer output and pacer rate. The unit interface also has specific buttons for defibrillation, including the ENERGY SELECT button, the CHARGE button, the ANALYZE button and the SHOCK button. The five softkeys underneath the display provide specific operations depending on the unit’s configuration. The other push buttons (from left to right) are used for volume control, monitor illumination, summary report, and code markers. The CHARGER ON indicator displays the status of the unit’s power supply.

This input module on the front panel and the Main System Board provides a beeper for the AC/DC Power/Battery

Charger.

The Controls PWBA is physically located in the front panel assembly. Units that are equipped for voice recording include a microphone and audio signal conditioning circuitry on the Controls PWBA.

M Series Options

This section describes four options for the M Series unit.

112

M Series Service Manual

Isolated Power Supply Module

The Isolated Power Supply Module provides electrically isolated power to the EtCO

2 and SpO

2 modules. It also provides the electrically isolated serial communications and isolated control signals between the EtCO

2 and SpO

2 modules and the main system PWBA.

12 Lead Option

The ZOLL M Series 12 lead option is used to acquire ECG data needed to assist in the diagnosis of myocardial infarction (“heart attack”), often caused by a coronary artery occlusion. The 12 lead ECG can be viewed on the display one lead at a time in monitoring and diagnostic bandwidths and printed in the standard 4×3 format with 12 simultaneously acquired leads.

The 12 lead option provides for the recording, printing and automated analysis of 12 lead ECG using GE Marquette

12SL

™ Analysis and supports the transmission of these reports by fax to a remote location, such as a hospital. In the pre-hospital environment, the 12 lead reports can be faxed to a physician as the patient is en route to the Emergency

Department. As a result, the physician can initiate hospital accommodations immediately, such as activating the staff of the cardiac catheterization lab, prior to the patient’s arrival and subsequent treatment. Or the patient may be treated in the pre-hospital environment with thrombolytic agents.

The 12 lead cable is required to produce 12 lead reports. M Series unit must have the 12 lead option installed. All limb leads and at least one V-lead must be connected to initiate a 12 lead acquisition. Printed 12 Lead bandwidth is user configurable to be either 0.05-150 Hz (per AAMI EC11) or 0.05-40 Hz. The 0.05-40 Hz bandwidth selection is used to reduce noise artifact in the high end of the diagnostic frequency range. Reports can be printed in a standard 4×3 or

Cabrera format. Faxed reports can be configured in a 2×6 format in addition to 4×3 and Cabrera formats.

The GE Marquette 12SL

™ Analysis algorithm provides measurements of the 12 lead waveforms along with interpretive statements. The algorithm is interpretive, not “diagnostic.” (A physician should always confirm interpretive statements. A diagnosis requires a complete clinical assessment including other modalities, such as a physical examination.) 12SL

™ produces global waveform measurements as well as a measurement matrix containing measurements on each lead. Both the interpretive statements and measurement matrix are configurable to be printed or not printed.

113

M Series Service Manual

The acquired 12 lead with 12SL

™ may be faxed to a remote location using landline or cellular phone technology.

Several PCMCIA fax modems are supported and the modem determines the specific phone compatibility. Cellular phone support includes analog AMPS phones (in the U.S.) and GSM phones (internationally). The M-Series supports

Group 3 facsimile, Class 1 and Class 2. 12 lead reports may be re-printed or re-transmitted using the Patient Records capability. Individual patient records may be selected based on patient ID, date, and time.

Pulse Oximetry (S

P

O

2

)

The ZOLL M Series pulse oximetry option enables the user to continuously, noninvasively, and painlessly monitor the percentage of oxygen saturation of arterial hemoglobin at a peripheral measurement site (i.e.foot, toe or finger.)

The oximetry sensor contains two light emitting diodes, or LEDs, that transmit red and infrared light through the body’s extremities. A photodetector receives the transmitted light. Oxygen saturated blood absorbs light differently than unsaturated blood. Thus the amount of red and infrared light absorbed by the blood flowing through a suitable peripheral area of the body, such as the finger in adults and the foot in neonates, can be used to calculate the ratio of oxygenated hemoglobin to total hemoglobin in the arterial blood. The monitor displays this ratio as percent SpO

2

.

Normal values typically range from 95% to 100% at sea level.

The M Series uses a Masimo

®

Pulse Oximetry Circuit Board which features a fundamentally distinct method of acquiring, processing and reporting arterial oxygen saturation and pulse rate. The M Series’ SpO

2

module (Masimo

®

Circuit Board) connects to the Masimo sensors and reports monitoring results (oxygen saturation, pulse rate, pulse waveform, etc.) via a serial digital interface to the M Series system board. The M Series system provides isolated DC power and serial communication to the SpO

2

Board via the Isolated Power Supply board.

End Tidal Carbon Dioxide (EtCO

2

)

The ZOLL M Series EtCO

2

Novametrix technology and Capnostat

®

sensor option continually and noninvasively monitors the patient’s carbon dioxide in respiratory gases and from these measurements computes End Tidal CO

2

and respiration rate. The unit can display and print a recording of EtCO

2

readings, respiration rates, and capnograph waveforms. In addition, the unit can configure an alarm to sound when the unit detects EtCO

2

values and respiration rates that are above or below acceptable ranges as set by the user. This option is intended for use in all critical monitoring environments including ventilator support, patient transport, and anesthesia and is intended for monitoring all patient types, including adult, pediatric, and neonatal.

114

M Series Service Manual

The EtCO

2

option incorporates, without modification, the Novametrix respiratory carbon dioxide technology, including a printed circuit board, and a patented and proprietary mainstream CO

2 sensor and reusable/disposable airway adapters. Carbon dioxide measurements are monitored by using a solid-state infrared Capnostat

®

sensor which works on the principles of infrared absorption.

The M Series system board software transmits commands to the Novametrix board to set parameters (averaging mode, oxygen, and nitrous oxide compensation) and retrieves CO

2

waveform, EtCO

2

, and respiration rate data. The M Series software formats the data for output to the display and strip chart recorder. In addition, the M Series software performs range checking of the Novametrix data to determine the presence of low or high EtCO

2

and respiration rate alarm limit violations. If the limits have been violated, the software issues audio and visual alarms.

The Capnostat

® mainstream sensor is attached to an airway adapter that connects to an endotracheal tube, similar airway, or disposable mouthpiece. The sensor generates infrared light and beams it through the airway adapter to a detector on the opposite side of the airway. As a result of respiration, CO

2

flowing through the airway adapter absorbs some of this infrared energy. The monitor relates the amount of detected energy to the amount of CO

2 in the airway adapter. The CO

2 display reflects the maximum concentration of CO

2

detected during expiration. End-Tidal Carbon

Dioxide (EtCO

2

) displays as a numerical value in millimeters of mercury (mmHg), percent (%), or kilopascals (kPa) on the unit. In addition, a capnogram waveform may display underneath the ECG waveform.

The EtCO

2

option uses Non-Dispersive Infrared (NDIR) absorption and dual wavelength ratiometric-True Single

Beam Optics. The Capnostat

®

sensor contains the NDIR light source. Carbon dioxide, flowing in the airway adapter as a result of respiration, absorbs some of this light energy.

Biphasic Waveform

The M Series Biphasic Waveform Defibrillator produces a rectilinear biphasic defibrillator waveform similar to the chart shown at the end of this section. The electrical energy is delivered in two successive current phases of opposite polarity. As compared to the monophasic waveform, the biphasic waveform typically defibrillates with substantially less current than the earlier monophasic waveform used by most defibrillators.

The M Series Biphasic Defibrillator system consists of circuitry and software located on the following assemblies:

1. Main System PWBA.

2. High Voltage Module.

3) Biphasic Bridge PWBA Module.

115

M Series Service Manual

The High Voltage module controls the monitoring, charging, and internal discharges of the defibrillator capacitor. The

Bridge module controls capacitor discharge, including waveform polarity control, patient current and voltage monitoring during discharge and real-time control over defibrillator internal impedance to create the rectilinear waveshape. The main CPU controls the waveform timing and resistor switching performed by the Bridge Module based upon measured patient transthoracic impedance.

The Biphasic Bridge Assembly is constructed as two printed wire board assemblies (PWBAs) containing the power and isolation circuits required to deliver a biphasic defibrillation pulse. These boards produce a defibrillation pulse consisting of a positive current pulse followed by a negative current pulse. The positive portion of the pulse is shaped to be rectilinear by switching resistors in series with the patient to compensate for droop in the capacitor voltage as it delivers energy to the patient load.

The ZOLL Biphasic units produce a rectilinear waveform whose shape remains essentially constant from patient to patient. The rectilinear biphasic waveform consists of a 6 millisecond, essentially constant current first phase followed by a 4 millisecond, truncated exponential second phase. The first and second phases of the defibrillation waveform are of opposite polarity and their amplitudes vary based on the user selected therapeutic energy level. The initial amplitude of this waveform’s second phase is approximately equal to the first phases’s final amplitude. This wavefrom has an integrated patient impedance measurement sensing pulse at the beginning of the waveform. The positive and negative phases are separated by 100

µsec.

Electronics and software control the shape of the waveform’s first phase and compensate for different transthoracic impedances to maintain an essentially constant current throughout the first phase.When the highest energy setting is selected and patient impedance exceeds 85 ohms, the first phase of the waveform will droop. All other waveform parameters (phase duration, inter-phase delay and integrated impedance measurement sensing pulse) remain the same.

116

M Series Service Manual

The following Rectilinear Biphasic Waveform is produced when the M Series with Biphasic option is discharged into a 50 ohm load at the default energy setting of 120 joules. The vertical axis is in amperes; the horizontal axis is in milliseconds. (See following diagram.)

Бифазный — 1

Версия А

ПРЯМОУГОЛЬНЫЙ ДВУХФАЗНЫЙ
ДЕФИБРИЛЛЯЦИОННЫЙ ИМПУЛЬС
Общая информация

Введение

Существуют дефибрилляторы M Series

®

с усовершенствованной электрической конструкцией, обеспечивающей

уникальную бифазную форму импульса дефибрилляции и кардиоверсии. В этой опции электроэнергия
дефибриллятора передается в двух последовательных фазах тока (напряжения) противоположной полярности. Этот
тип формы волны дефибриллятора обычно называется «бифазным» в противопоставление более ранней
«монофазной» демпфированной синусоидальной волне, присущей для большинства имеющихся в продаже
дефибрилляторов.

Прямолинейный бифазный импульс дефибриллятора ZOLL M Series имеет уникальные характеристики,
предназначенные для получения оптимальных клинических результатов и проверенные в многоцентровых
клинических испытаниях. Клинические испытания продемонстрировали, что эта форма дефибрилляционного
импульса клинически эффективна как для дефибрилляции, так и для синхронизированной кардиоверсии.

В настоящем вкладыше объясняется, чем прямоугольный бифазный импульс дефибриллятора M Series отличается
от монофазного импульса в виде демпфированной синусоиды других приборов M Series. Его следует использовать
совместно с руководством по эксплуатации для дефибрилляторов M Series. Важная информация по технике
безопасности, относящаяся к общему использованию M Series, дается в разделе «Рекомендации по технике
безопасности» руководства по эксплуатации дефибрилляторов M Series.

Показания к применению M Series с прямолинейным бифазным импульсом

Приборами ZOLL M Series с бифазным импульсом должен пользоваться только квалифицированный медицинский
персонал для проведения преобразования жизнеугрожающих аритмий: вентикулярной фибрилляции (VF) и/или
вентикулярной тахикардии (VT), в нормальный синусовый ритм или другие сердечные ритмы, обеспечивающие
гемодинамическую стабильность.
Кроме того, этот прибор должен использоваться в синхронизированном режиме только квалифицированным
медицинским персоналом для устранения фибрилляции предсердий (AF) на более низких значениях дозы энергии и
силы тока, чем у монофазных дефибрилляторов. Квалифицированный врач должен решить самостоятельно, когда
необходима синхронизированная кардиоверсия.
Этот прибор также должен использоваться в синхронизированном режиме только квалифицированным медицинским
персоналом для электроимпульсной терапии вентикулярной тахикардии (VT). Квалифицированный врач должен
решить, когда необходима синхронизированная кардиоверсия.
Прямолинейный бифазный импульс (RBW) прошел успешную проверку в многоцентровых рандомизированных
клинических испытаниях эффективности трансторакальной дефибрилляции VT/VF и AF, которые подтвердили
возможность и эффективность проведения бифазной дефибрилляции и кардиоверсии у взрослых пациентов при
более низких значениях дозы энергии и силы тока, чем у существующих монофазных приборов. Бифазный импульс
M Series имеет широкий диапазон доз энергии, выбираемых пользователем, включая более низкие значения
энергии, чем те, которые были использованы во время клинических испытаний.
Автоматический (АНД) и консультативный режимы дефибрилляции следует использовать только при
подтвержденном диагнозе фибрилляции желудочков у пациентов со следующими симптомами:

пациент должен быть без сознания.

у пациента должна быть остановка дыхания (не дышит).

у пациента должен отсутствовать пульс.

ВНИМАНИЕ

Нельзя использовать автоматический режим для пациентов младше
8 лет (В соответствии с Рекомендациями АНА по сердечно-легочной
реанимации взрослых и автоматической дефибрилляции 3-5, 1998 г.)
