Rationale for change

"Conventional pulse oximeter: The displayed oxygen saturation is decreased and often fixed ∼ 85%."

FA24 "Oxidized form of Hb
(ferric, Fe3+) does not bind O2
as readily as Fe2+ tissue hypoxia from decreased O2 saturation "

Extra Extra
Text
Methemoglobin (Fe3+) binds O2 much {{c1::less::more/less}} readily than hemoglobin (Fe2+)
