Abstract

SpO2 is routinely used to assess the well-being of patients, but it is difficult to find an evidence-based description of its normal range. The British Thoracic Society (BTS) has published guidance for oxygen administration and recommends a target SpO2 of 94–98% for most adult patients. These recommendations rely on consensus opinion and small studies using arterial blood gas measurements of saturation (SaO2). Using large datasets of routinely collected vital signs from four hospitals, we analysed the SpO2 range of 37,593 acute general medical inpatients (males: 47%) observed to be breathing room air. Age at admission ranged from 16 to 105 years with a mean (SD) of 64 (21) years. 19,642 admissions (52%) were aged
