• Rescue Ready defibrillator technology self-tests all main components (battery, hardware, software, and pads) daily. Powerheart Automatic and Semi-Automatic Defibrillators complete a partial charge of the high-voltage electronics weekly, and a full charge monthly.
• Calculates electrical impedance and if subsequent shocks are necessary, our proprietary STAR biphasic technology escalates the energy to deliver therapy at an appropriate, higher level.
• The text screen lends extra help in noisy and chaotic environments
