Abstract
Inaccuracy of pulse oximetry measurements of oxygen saturation in darker-skinned individuals https://bit.ly/3rVzRpN
Reply to M.J. Tobin and A. Jubran:
We thank M.J. Tobin and A. Jubran for their interest in our data [1]. As they state, it is an extension of a body of work that they helped establish over 30 years ago.
We do not have reliable data on whether these patients were ventilated or not, as the electronic data that we had access to excluded the period of time when patients were admitted to intensive care. For those patients with a paired pulse oximeter and arterial blood gas reading, with a reading of <85% arterial saturation (unique patients n=644), 287 (45%) were labelled as eligible for escalation to the intensive care unit (ICU), and of these 143 (50%) were admitted to ICU within 24 h of the blood gas measurement, and 172 (60%) were admitted to ICU at any point during the whole admission period.
