A pleth wave, short for plethysmographic wave, refers to a waveform generated by a plethysmograph, which is a device used to measure changes in blood volume. The pleth wave typically represents the pulsatile changes in blood volume in a specific body part, such as a finger or earlobe, and is commonly used in medical settings to monitor cardiovascular function and assess peripheral perfusion. The shape and characteristics of the pleth wave can provide valuable information about a patient's hemodynamic status and vascular health.
