Unexpectedly low pulse oximetry measurements associated with variant hemoglobins: a systematic review.

American journal of hematology - 1 Nov 2010

Abstract excerpt

Pulse oximetry estimates arterial blood oxygen saturation based on light absorbance of oxy- and deoxy-hemoglobin at 660 and 940 nm wavelengths. Patients with unexpectedly low SpO₂ often undergo cardio-pulmonary testing to ascertain the cause of their hypoxemia. However, in a subset of patients, a...
