Synchronization of repetitive therapeutic interventions
First Claim
1. A method of measuring blood flow in the vertebral artery during cardiac resuscitation, the method comprisingpositioning an ultrasonic probe at the end of a catheter,inserting the probe and catheter into or at the opening of the esophagus,wherein the probe is configured to deliver and measure ultrasonic sound energy posteriorly toward the spine at approximately the cervical vertebra C3-C6, to estimate blood flow in the vertebral artery;
- andusing a processor, memory, and associated circuitry to process the output of the probe to estimate blood flow achieved by CPR chest compressions in the vertebral artery by ultrasonic Doppler flow measurement.

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.
