Concurrent measurements of oxygen saturation levels ended up done in arterial blood (SaO2) and by pulse oximetry (SpO2) the proportion of patients with occult hypoxemia was in comparison by race and ethnicity. A whole of 1,216 patients experienced 32,282 concurrently measured SpO2 and SaO2.
The researchers discovered that occult hypoxemia transpired in 30.2, 28.5, and 29.8 per cent of Asian, Black, and non-Black Hispanic individuals in contrast to 17.2 p.c of White clients.
