Indications for Use
The LIFEPAK 1000 defibrillator is intended for indoor or outdoor use in a wide variety of hospital and pre-hospital settings including ground and air ambulances, physician's offices, aircraft, stadiums and specialty medical clinics. It is intended for use by personnel who are authorized by a physician/medical director and are trained in CPR and the use of the LIFEPAK 1000 defibrillator. The manual and ECG modes of the LIFEPAK 1000 defibrillator are intended for use by health care providers trained in ECG rhythm recognition. Defibrillation is a recognized means of terminating certain potentially fatal arrhythmias, such as ventricular fibrillation and symptomatic ventricular tachycardia. The LIFEPAK 1000 defibrillator is to be used in AED mode only on patients who are in cardiopulmonary arrest. The patient must be unresponsive, not breathing normally, and showing no signs of circulation. The defibrillator may be used with standard defibrillation pads only on adults and children who are 8 years old or more or who weigh more than 25 kg (55lbs). The defibrillator may be used on children who are less than 8 years old or weigh less than 25 kg (55 lbs) with Infant/Child Reduced Energy Defibrillation Electrodes. ECG monitoring is intended for use on conscious and unconscious patients of all ages for the purpose of ECG rhythm recognition and heart rate monitoring.
Device Story
Semi-automatic defibrillator with optional manual and ECG modes; inputs include ECG signals via defibrillation electrodes or monitoring cables. Device processes signals to identify fatal arrhythmias (ventricular fibrillation/tachycardia); provides automated analysis in AED mode or manual control for skilled clinicians. Outputs include voice prompts, ECG display, and therapeutic electrical shocks. Used in hospital/pre-hospital settings (ambulances, clinics, aircraft) by trained personnel. Healthcare providers use ECG output for rhythm recognition and heart rate monitoring; manual mode allows clinician-directed therapy. Benefits include rapid termination of life-threatening arrhythmias in cardiac arrest.
Clinical Evidence
Bench testing only. Documentation provided regarding conformance to electrical safety, electromagnetic compatibility, and defibrillator standards. No clinical trial data presented.
Technological Characteristics
Semi-automatic defibrillator; manual/ECG modes. Power: non-rechargeable lithium manganese battery. Connectivity: serial infrared link. Sensing: ECG rhythm/heart rate via electrodes or ECG cable. Form factor: portable unit for indoor/outdoor use. Software: automated rhythm analysis.
Indications for Use
Indicated for patients in cardiopulmonary arrest (unresponsive, apneic, pulseless) for defibrillation therapy. AED mode for adults/children >8 years or >25kg; pediatric mode with reduced energy electrodes for children <8 years or <25kg. ECG monitoring indicated for conscious/unconscious patients of all ages for rhythm/heart rate assessment.
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.
