The oxyhaemoglobin dissociation curve is generally left‐shifted in COVID‐19 patients at admission to hospital, and this is associated with lower mortality

Summary Lung damage caused by SARS‐Cov‐2 virus results in marked arterial hypoxia, accompanied in many cases by hypocapnia. The literature is inconclusive as to whether these conditions induce alteration of the affinity of haemoglobin for oxygen. We studied the oxyhaemoglobin dissociation curves (OD...
