Abstract
A medical device of the type used for assisting a user in manually delivering repetitive therapy to a patient (e.g., chest compressions or ventilations in cardiac resuscitation), the device comprising a feedback device configured to generate feedback cues to assist the user in timing the delivery of the repetitive therapy, at least one sensor or circuit element configured to detect actual delivery times, at which the user actually delivers the repetitive therapy, and a processor, memory, and associated circuitry configured to compare the actual delivery times to information representative of desired delivery times to determine cue times at which the feedback cues are generated by the feedback device.
Claims17
A medical device for assisting a user in manually delivering chest compressions and/or ventilations to a patient as part of cardiac resuscitation, the device comprising
- a feedback device configured to generate feedback cues to assist the user in timing the delivery of the chest compressions and/or ventilations, wherein compressions comprise an upstroke phase and a downstroke phase;
- a processor, memory, and associated circuitry configured to determine cue times at which the feedback cues are generated by the feedback device,
- wherein the feedback cues are auditory and non-verbal, and if both compression and ventilation cues are generated, the feedback cue for chest compressions is a different sound from the feedback cue for ventilations, and the difference in sound between the compression and ventilation cues comprises a difference in tone, and
- wherein at least one of the feedback cues comprises a changing sound, wherein the change in sound is configured to improve the quality of the delivered compressions and/or ventilations.
