Finger probes may outperform alternatives in poor perfusion; hypothesis-generating and should not yet change practice.
Do alternative pulse oximeter probes (ear, nose, forehead) perform as well as finger probes in poorly perfused patients?
Finger probes are recommended over alternative sites (ear, nose, forehead) for pulse oximetry in patients with poor peripheral perfusion due to superior accuracy.
Clayton et al. (1991) studied this question.
