AI summary

Various exemplary embodiments of the present disclosure encompass a physiological monitor for monitoring a physiological parameter of a patient during cardiopulmonary resuscitation (“CPR”) on the patient and a mechanical CPR device having an adjustable configuration for regulating chest compressions on the patient during CPR on the patient. During the CPR on the patient, an exemplary CPR controller controls the adjustable configuration of the mechanical CPR device based on sustaining the physiological parameter monitoring of the patient by the physiological monitor at a baseline physiological parameter level for the patient.
