Weighing just 3.3lb, this small and lightweight defibrillator can be easily carried to the patient’s side. Using clear, natural voice instructions, the OnSite defibrillator guides the user through each step of defibrillation and CPR. Integrated Smart pads placed on the patient’s bare skin transmit information to the defibrillator, which senses and adapts to the user’s actions every step of the way. Heart Start® OnSite includes proven Philips technologies for heart rhythm assessment (Smart Analysis) and defibrillation energy delivery (Smart Biphasic). And like all Heart Start® defibrillators, it can be used to treat adults, as well as infants and children. Between uses, the Heart Start® OnSite performs daily, weekly and monthly self-tests of its electrical components, subsystems and battery to help ensure continued reliability and readiness. A pads integrity test, which checks that the cartridge is properly installed and that the defibrillator pads are in working order, provides an additional level of assurance. Includes one pair of adult defib pads, one long-life (four-year) battery, directions for use and five-year warranty.
