Classification: CPC A  G | IPC A

Claim 18:
19. A medical device, comprising:
an emitter configured to emit a signal toward a blood vessel of a patient, the signal comprising electromagnetic waves or mechanical waves;
a detector configured to receive a reflection of the signal from the blood vessel or blood flowing through the blood vessel; and
a processor configured to:
determine a metric by analyzing the reflection;
determine, by analyzing an electrocardiogram (ECG) of the patient and the metric, whether the patient has pulseless electrical activity (PEA); and

output an indication of whether the patient has PEA,
wherein determining the metric by analyzing the reflection comprises:
determining a pulse wave velocity of the blood vessel, and

determining an instantaneous blood velocity of the blood flowing through the blood vessel, wherein the pulse wave velocity and the instantaneous blood velocity are determined simultaneously.
