Why the study?
Cuff devices can modulate arterial blood flow and pulse propagation, offering potential to reveal critical care compensatory mechanisms, but previous characterizations neglected distal vasculature effects.

Cuff inflation may transiently alter distal hemodynamics; leaves open whether novel sensor arrangements can reliably inform compensatory mechanisms in critical care.
Does cuff inflation modulate distal blood flow and pulse propagation in patients monitored in the OR?
Cuff inflation significantly alters distal hemodynamics, increasing mean arterial pressure and decreasing pulse transit time, which can inform new cuff-based measurement strategies.
