What is the P₅₀ in the healthy adult?

Question

Quizplus · Accepted Answer

P₅₀ is a code for a pulse oximeter reading, but it does not provide information on COHb levels. A healthy adult should have an oxygen saturation (SpO2) level of around 97-99%, which corresponds to a partial pressure of oxygen (PaO2) of around 80-100 mm Hg. Therefore, the closest answer choice is A, 27 mm Hg, which corresponds to a SpO2 level of around 50%. However, it is important to note that a SpO2 level of 50% is not healthy and may indicate severe respiratory or circulatory impairment.
