Device Story

ZOLL M Series with Real CPR Help is a portable defibrillator/monitor for critical care and transport. It integrates with specialized multi-function electrodes (CPR-D-padz, CPR Stat-padz) containing a sensor assembly. The device receives real-time chest compression depth and rate data from the sensor. An internal processor compares this data against AHA/ERC guidelines (100 compressions/min; 1.5-2 inch depth). It provides feedback via metronome, voice prompts, and visual symbols/text on the display. The device also features an advisory algorithm to analyze ECG signals for shockable/non-shockable rhythms. Used by qualified medical personnel or trained emergency responders to guide resuscitation efforts. Output allows providers to adjust compression technique in real-time, potentially improving CPR quality and patient outcomes.

Clinical Evidence

Bench testing only. Functional testing verified that the Real CPR Help software integration did not impact existing device features, functions, or performance specifications. Safety testing confirmed compliance with recognized industry and safety standards.

Technological Characteristics

Portable defibrillator/monitor. Sensing: CPR sensor assembly in multi-function electrodes for compression depth/rate. Energy: Defibrillation and noninvasive transcutaneous pacing. Connectivity: Data printing/recording. Software: Rule-based feedback algorithm for CPR performance. Sterilization: N/A (external device).

Indications for Use

Indicated for adult patients (8+ years) requiring CPR assistance. Used by trained emergency care personnel for defibrillation, noninvasive transcutaneous pacing, and multi-parameter vital sign monitoring (ECG, SpO2, CO2, NIBP) in critical care and transport environments. Semiautomatic mode indicated for cardiac arrest victims (unconscious, no breathing, no pulse).

Regulatory Classification

Identification

An automated external defibrillator (AED) system consists of an AED and those accessories necessary for the AED to detect and interpret an electrocardiogram and deliver an electrical shock (e.g., battery, pad electrode, adapter, and hardware key for pediatric use). An AED system analyzes the patient's electrocardiogram, interprets the cardiac rhythm, and automatically delivers an electrical shock (fully automated AED), or advises the user to deliver the shock (semi-automated or shock advisory AED) to treat ventricular fibrillation or pulseless ventricular tachycardia.

## External Pacemaker (Pacer Version Only)

#### Intended Use -- Pacemaker

This product may be used for temporary external cardiac pacing in conscious or unconscious patients as an alternative to endocardial stimulation.

Note: This device must not be connected to internal pacemaker electrodes.

The purposes of pacing include:

## Resuscitation from standstill or bradycardia of any etiology:

Noninvasive pacing has been used for resuscitation from cardiac standstill, reflex vagal standstill, drug induced standstill (due to procainamide, quinidine, digitalis, b- blockers, verapamil, etc.) and unexpected circulatory arrest (due to anesthesia, surgery, angiography, and other therapeutic or diagnostic procedures). It has also been used for temporary acceleration of bradycardia in Stokes-Adams disease and sick-sinus syndrome. It is safer, more reliable, and more rapidly applied in an emergency than endocardial or other temporary electrodes.

#### As a standby when standstill or bradycardia might be expected:

Noninvasive pacing may be useful as a standby when cardiac arrest or symptomatic bradycardia might be expected due to acute myocardial infarction, drug toxicity, anesthesia or surgery. It is also useful as a temporary treatment in patients awaiting pacemaker implants or the introduction of transvenous therapy. In standby pacing applications, noninvasive pacing may provide an alternative to transvenous therapy that avoids the risks of displacement, infection, hemorrhage, embolization, perforation, phlebitis and mechanical or electrical stimulation of ventricular tachycardia or fibrillation associated with endocardial pacing.

#### Suppression of tachycardia:

Increased heart rates in response to external pacing often suppress ventricular ectopic activity and may prevent tachycardia.

#### Pediatric Pacing

Pacing can be performed on pediatric patients weighing 33lbs / 15kg or less using special ZOLL. pediatric MFE Pads. Prolonged pacing (in excess of 30 minutes), particularly in neonates, could cause burns. Periodic inspection of the underlying skin is recommended.
