Arterial waveform morphomics during hemorrhagic shock

The arterial pressure waveform is a composite of multiple interactions, and there may be more sensitive and specific features associated with hemorrhagic shock and intravascular volume depletion than systolic and/or diastolic blood pressure (BP) alone. The aim of this study was to characterize the arterial pressure waveform in differing grades of hemorrhage. Ten anesthetized swine (70–90 kg) underwent a 40% controlled exponential hemorrhage....
