PULSE DETECTION APPARATUS, SOFTWARE, AND METHODS USING PATIENT PHYSIOLOGICAL SIGNALS

摘要

Appropriate cardiac therapy is determined by data sensed and analyzed by the disclosed defibrillators and other medical devices that one or both of treat and monitor a patient. The disclosed devices sense various patient physiological parameters including patient pulse and breathing data to determine whether the patient has a pulse and to determine if the patient is breathing. Depending on the analysis of the generated patient physiological data, the disclosed devices determine the appropriate therapy for the patient, which can include providing breathing assistance to the patient and providing electrotherapy and other therapies to the patient. Some of the disclosed medical devices can be wearable by the patient. The disclosed devices can include therapy modules like electrotherapy for delivering therapies to the patient while other devices monitor but do not deliver the therapies to the patient.

主权项

1. An external defibrillator, comprising:
a pulse sensor configured to sense a pulse of a patient and output patient pulse data; a breathing detection device configured to detect whether the patient is breathing and to output patient breathing data; a controller operatively coupled to the pulse sensor and the breathing detection device and configured to
analyze the output patient pulse data;determine that the patient has a pulse based on the analyzed output patient pulse data;analyze the output patient breathing data;determine that the patient is not breathing based at least in part on the analyzed output patient pulse data; andgenerate an instruction to provide breathing assistance to the patient based on the determination that the patient has a pulse and the determination that the patient is not breathing; and an output device configured to issue a prompt to provide breathing assistance to the patient based on the generated instruction.
