A pulse oximeter reading will be most accurate when used with a patient in which of the following situations?
A) An intensive care unit patient with hyperbilirubinemia
B) A hypotensive patient receiving peripheral vasoconstrictors
C) An emergency department patient with evidence of smoke inhalation
D) An open heart patient receiving extracorporeal membrane oxygenation

Question

Quizplus · Accepted Answer

Hyperbilirubinemia does not appear to affect pulse oximetry measurements as do low perfusion states,which are caused by the use of peripheral vasoconstrictors or extracorporeal membrane oxygenation (ECMO).Carbon monoxide poisoning will lead to an overestimation of oxygen saturation measured by pulse oximeter (SₚO₂).
