Agreement between pulse oximetry and arterial oxygen saturation measurement in critical care patients during COVID-19: a cross-sectional study.

ABSTRACT: Some publications suggest that pulse oximetry measurement (SpO₂) might overestimate arterial oxygen saturation (SaO₂) measurement in COVID-19 patients. This study aims to evaluate the agreement between SpO₂ and SaO₂ among COVID-19 and non-COVID-19 patients. We conducted a multicenter, prospective study including consecutive intensive care patients from October 15, 2020, to March 4, 2021, and compared for each measurement the difference between SpO₂ and SaO₂, also called the systematic bias. The primary endpoint was the agreement between SpO₂ and SaO₂ measured with the Lin concordance coefficient and illustrated using the Bland and Altman method. Factors associated with systematic bias were then identifi
