The effects of passive leg raising may be detected by the plethysmographic oxygen saturation signal in critically ill patients
BACKGROUND: A passive leg raising (PLR) test is positive if the cardiac index (CI) increased by > 10%, but it requires a direct measurement of CI. On the oxygen saturation plethysmographic signal, the perfusion index (PI) is the ratio between the pulsatile and the non-pulsatile portions. We hypot...
