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.

Claims

1. A method of delivering a second repetitive therapy while repetitive chest compressions are being delivered, comprising

detecting the timing of the repetitive chest compressions;

and

delivering the second repetitive therapy at times that are synchronized to a selected phase of the repetitive chest compressions.

2. The method of claim 1 wherein the second repetitive therapy comprises electromagnetic pacing stimuli.

3. The method of claim 2 wherein the pacing stimuli are subthreshold and configured to improve tone of myocardium.

4. The method of claim 2 wherein the pacing stimuli are above threshold and configured to produce cardiac contractions.

5. The method of claim 1 wherein the chest compressions are being delivered manually.

6. The method of claim 1 wherein the chest compressions are being delivered by an automatic device.
