20007731-14	2010	Occurrence of methemoglobin readings in error >5% increased over each 5-point decrease in Sao2 (P < 0.05).	sao2	93-97	hemoglobin subunit gamma 2	Homo sapiens	14-27	
8366629-4	1993	With a decrease of methemoglobin level, SpO2 approached SaO2.	sao2	56-60	hemoglobin subunit gamma 2	Homo sapiens	19-32	
20007731-17	2010	CONCLUSIONS: The Radical-7"s methemoglobin readings become progressively more inaccurate as Sao2 decreases <95%, at times overestimating true values by 10% to 40%.	sao2	92-96	hemoglobin subunit gamma 2	Homo sapiens	29-42
