Intended Use

The HeartStart MRx is for use for the termination of ventricular tachycardia and ventricular fibrillation. The device is for use by qualified medical personnel trained in the operation of the device and qualified by training in basic life support, advanced cardiac support, or defibrillation. It must be used by or on the order of a physician. The SMART Biphasic waveform utilized in the Heartstream XL Defibrillator/Monitor has previously undergone clinical testing in adults. These trials support the waveform's effectiveness for defibrillation of ventricular tachyarrhythmias at 150J. There are currently no clinical studies related to the use of SMART Biphasic waveform in pediatric applications. Manual Defibrillation: Asynchronous defibrillation is the initial treatment for ventricular fibrillation and ventricular tachycardia in patients that are pulseless and unresponsive. Synchronized defibrillation is indicated for termination of atrial fibrillation. AED Therapy: To be used in the presence of a suspected cardiac arrest on patients of at least 8 years of age that are unresponsive, not breathing and pulseless. Non-Invasive External Pacing: The pacing option is intended for treating patients with symptomatic bradycardia. It can also be helpful in patients with asystole, if performed early. 12-Lead ECG: The 12-Lead ECG option is to be used where the clinician decides to evaluate the electrocardiogram of adult and pediatric patients as part of decisions regarding possible diagnosis, potential treatment, effectiveness of treatment or to rule out causes for symptoms. Non-Invasive Blood Pressure: The NIBP option is intended for noninvasive measurement of arterial blood pressure for adult and pediatric patients. Endtidal CO2: The EtCO2 option is intended for noninvasive monitoring of exhaled carbon dioxide and to provide a respiration rate for adult, pediatric and neonatal patients. Pulse Oximetry: The SpO2 option is intended for use when it is beneficial to assess the oxygen saturation level for adult and pediatric patients. The HeartStart MRx is a fully featured, external defibrillator/monitor intended for use by qualified medical personnel, trained in either Advanced Cardiac Life Support or Basic Life Support, in a hospital or pre-hospital environment.

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.

# Predicate Devices

The legally marketed devices to which Philips Medical Systems claims equivalence for the HeartStart MRx are as follows:

- Philips Medical Systems (formally Agilent Technologies) Heartstream XL . Defibrillator/Monitor, and
- . ZOLL Medical Corp. M Series Defibrillator

The design of the HeartStart MRx is substantially equivalent in safety and performance to the devices listed above.

# Device Description

The HeartStart MRx is a lightweight, portable external defibrillator, offering two modes of operation for defibrillation: manual mode and semi-automatic mode (AED).

In manual mode, the HeartStart MRx is a full-featured manual defibrillator, designed for use by clinicians trained in Advanced Cardiac Life Support (ACLS). Manual operation

{1}------------------------------------------------

allows users to select energy levels for external and internal defibrillation, perform synchronized cardioversion and provide non-invasive external pacing.

In AED mode, the HeartStart MRx, allows the provider who is trained in Basic Life Support (BLS) to provide defibrillation therapy. The device analyzes a patient's rhythm and advises the user to provide a shock. Voice prompts guide the user through the defibrillation process by providing instructions and patient information. The voice prompts are reinforced by messages that appear on the display.

In both modes of operation, the HeartStart MRx utilizes impedance compensating biphasic truncated exponential therapy waveform.

The HeartStart MRx can also be used for ECG monitoring of a patient using either 3 or 5 lead cables.

Additionally, the HeartStart MRx is offered with the following optional functionality:

#### Non-Invasive External Pacing:

The pacing option is intended for treating patients with symptomatic bradycardia. This parameter is used by ACLS trained clinicians typically performed in a hospital environment.

#### 12-Lead ECG:

The 12-Lead ECG option is intended to provide a conventional diagnostic 12-Lead ECG report, which may include measurements and interpretative statements. This parameter is used in both the hospital and pre-hospital environment by ACLS and BLS trained clinicians.

#### Non-Invasive Blood Pressure:

The NIBP option is intended for noninvasive measurement of a patient's arterial blood pressure. This parameter is used in both the hospital and pre-hospital environment by ACLS and BLS trained clinicians.

# Endtidal CO2:

The EtCO2 option is intended for noninvasive monitoring of a patient's exhaled carbon dioxide and also provides a respiration rate. This parameter is used by ACLS trained clinicians and performed in both the pre-hospital and hospital environments.

#### Pulse Oximetry:

The SpO2 option is intended for use when it is beneficial to assess a patient's arterial oxygen saturation level. This parameter is used by trained clinicians and performed in both the pre-hospital and hospital environments.

# Comparison of Technology Characteristics

The HeartStart MRx employs the same fundamental scientific technologies as the commercially available predicate devices used for comparison. The HeartStart MRx acquires and analyzes ECG signals, utilizes the same shock advisory criteria, and advises the user to deliver a shock when required utilizing voice prompts as in the Heartstream XL. Heart rate alarms, noninvasive pacing and pulse oximetry functions are provided, as in the Heartstream XL. The HeartStart MRx's 12-Lead ECG, NIBP, and EtCO2 technologies are substantially equivalent to the ZOLL M Series defibrillator.

# Tests Used in Determination of Substantial Equivalence

The tests used in the determination of substantial equivalence included only bench testing. Bench testing includes hardware and software testing demonstrating that the performance of the device meets its specification

# Conclusion from Testing

Based on the results of the testing described above, it is concluded that the HeartStart MRx does not raise any different questions regarding the safety or effectiveness as compared with the predicate devices. It is considered to be substantially equivalent to the predicate devices.
