Pulse detection apparatus, software, and methods using patient physiological signals

A device structured to provide one or both of treatment and monitoring of a patient, the device 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;
• and
• generate 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.
