Abstract
A warning apparatus for indicating the threat of impending shock, which includes a photoelectric pulse pickup or receiver adapted to be applied onto the skin of a patient. The pulse pickup or receiver is a combined reflective and transmissive receiver, and the pulse pickup has a signal comparison arrangement associated therewith which compares the signal obtained from a reflective and transmissive measurement with predetermined signal threshold or boundary values, and which will generate an output signal for initiation of an alarm when the output signal of the pulse pickup exceeds the boundary value imparted thereto.
