Discordance Between Invasive and NonInvasive Oxygen Saturation in Critically Ill COVID-19 Patients.

ABSTRACT:

Objectives

To investigate discordance in oxy-hemoglobin saturation measured both by pulse oximetry (SpO₂) and arterial blood gas (ABG, SaO₂) among critically ill coronavirus disease 2019 (COVID-19(+)) patients compared to COVID-19(-) patients.

Methods

Paired SpO₂ and SaO₂ readings were collected retrospectively from consecutive adult admissions to four critical care units in the United States between March and May 2020. The primary outcome was the rate of discordance (|SaO₂-SpO₂|>4%) in COVID-19(+) versus COVID-19(-) patients. The odds each cohort could have been incorrectly categorized as having a PaO₂/FiO₂ above or below 150 by their SpO₂: Fractional inhaled oxygen ratio (pul
