The AutoPulse is an automated, portable, battery-powered chest compressor, which provides chest compressions as an adjunct to performing manual CPR. Use of the AutoPulse is intended to reduce the impact of rescuer fatigue and will enable the rescuer to address additional patient needs. The AutoPulse has the following operating parameters: • Chest displacement: equal to 20% reduction in anterior-posterior chest depth. • Consistent compression rate and depth. • Physiological duty cycle: fixed at 50 ± 5%. • Standardized 30:2, or 15:2 compressions (30 or 15 compressions followed by two consecutive 1.5 second ventilation pauses) or continuous compressions (user selectable). The system is in Dutch language, and comes complete with 2 batteries, battery charger and lifeband.
