Racial bias in pulse oximetry measurement among patients about to undergo extracorporeal membrane oxygenation in 2019-2020: a retrospective cohort study.
This study examined whether pulse oximeters detect arterial hypoxemia less effectively in Black, Hispanic, and/or Asian patients than in White patients in respiratory failure who are about to undergo extracorporeal membrane oxygenation (ECMO). Data on adult patients with respiratory failure readings 6 hours before ECMO from 324 centers from January 2019 to July 2020 who were in the Extracorporeal Life Support Organization registry was used. The author’s primary analysis was of rates of occult hypoxemia-low arterial oxygen saturation (Sao(2) ≤ 88%) on arterial blood gas measurement despite a pulse oximetry reading in the range of 92% to 96%. The rate of pre-ECMO occult hypoxemia was 10.2% for 186 White patients with peripheral oxygen saturation; 21.5% for 51 Black patients; 8.6% for 70 Hispanic patients; and 9.2% for 75 Asian patients. The risk of occult hypoxemia was comparable for Hispanic and Asian patients to White patients, but the prevalence of occult hypoxemia was higher in Black patients than for White patients about to undergo ECMO for respiratory failure.

Pulmonary hypertension in the era of mechanical circulatory support.
The researchers summarized the literature available to highlight the definition, pathogenesis, and prognosis of pulmonary hypertension (PH) due to left heart disease (LHD). Additionally, they discussed the use of mechanical circulatory support (MCS) in this population. Then, they provided recommendations regarding the management and reassessment of PH due to LHD in the specific context of MCS.
