Systems and methods for generating neuroprotective and cardioprotective nutrition programs are described herein. These neuroprotective and cardioprotective nutrition programs are especially applicable for patients at risk of cardiac arrest (e.g. due to hypoxia or ischemia of the brain or other body parts). The programs may feature caloric restriction, for example, short-term caloric restriction. The programs may be generated or iteratively modified based on the hemodynamic and metabolic state of the patient's brain, limbs, or other tissues or organs. Dynamic feedback about the patient's hemodynamic and metabolic state may be provided by techniques including, but not limited to, optical technology for quantitatively and noninvasively measuring blood flow, oxygenation, metabolic rate of oxygen, and perfusion/metabolism ratio in the brain, limbs, or other tissues or organs. The systems described herein may also induce spreading depolarization and repolarization at specific times during or after cardiac arrest based on the patient's cerebral metabolic state.

A noninvasive blood pressure monitor. The noninvasive blood pressure monitor may include an inflatable cuff, a pressure transducer, one or more air pumps, and a processor. The processor may control the air pump(s) so as to initiate inflation of the cuff. The processor may also identify an oscillometric signal in an output of the pressure transducer, and may determine an envelope of the oscillometric signal. The processor may also determine one or more characteristics of the envelope of the oscillometric signal, and may control the air pump(s) so as to stop inflation of the cuff based on the one or more characteristics of the envelope of the oscillometric signal.
