摘　　要：To the Editor:The latest generation of pulse oximeters are equipped with technology allowing for monitoring of the peripheral perfusion index(PI),the percentage of the amount of light absorbed by pulsatile tissue(variable arterial blood flow)over non-pulsatile tissue(venous blood,muscle,and other tissues)at a wavelength of 940 nm as a signal.
