  • Automated external defibrilator with the ability to store rescue information
    Patent number: 6668192
    Abstract: An automated external defibrillator (AED) includes the ability to store rescue information. The AED has a case for housing a power supply that is electrically connected to a circuit for generating a defibrillation pulse. The circuit is electrically connected to a pair of electrodes that are applied to a patient to deliver the defibrillation pulse. The AED further comprises an archival storage means for storing rescue information. The archival storage means is containable within the case and is able to store various types of rescue information including patient data, operational data of the AED, and sound that occurs within the immediate vicinity of the AED during a rescue.

  • Field programmable automated external defibrillator
    Patent number: 6088616
    Abstract: An automated external programmable defibrillator (AED) with the ability to perform operational self-tests, determine whether a patient is undergoing cardial defibrillation, deliver an electrical defibrillation pulse, store data pertaining to the self-tests. Certain operational parameters are alterable by software installable in a computer. The operational parameters include second defibrillation shock energy value, the maximum shocks to be delivered during a rescue, whether the same energy will be delivered to the patient upon conversion to a shockable rhythm, whether the AED will automatically convert to daylight savings time, whether an electrode test will occur during the self-test, and whether ambient sound will be recorded during a rescue.

  • Automated external defibrillator with the ability to sense temperature
    Patent number: 5897576
    Abstract: The AED of the present invention has a housing and a removable power supply, contained within its own power supply case, that is connected to a circuit for generating a defibrillation pulse. The circuit is electrically connectale to a pair of electrodes for delivering the defibrillation pulse. the AED further includes a temperature sensing device that is mounted inside the power supply case and connected to the power supply. The temperature sensing device senses the temperature in the power supply case and enables the adjustment of the operating parameters of the AED according to the sensed temperature.
