- Happy Hypoxia has gained media coverage during COVID19. What is Happy Hypoxia?
- This article explores the phenomenon of ‘happy hypoxia’ in COVID-19 and the possible mechanisms involved. A concise description of breathlessness, hypoxia and hypoxaemia is provided as well as the principles underpinning pulse oximetry. The limitation of pulse oximetry is also discussed.
- The aetiology of ‘happy hypoxia’ is unclear. A possible pathophysiological explanation could be that there is a dissociation between hypoxaemia and the sensation of breathlessness. Recent literature has questioned the accuracy of pulse oximetry in COVID-19. Inaccuracies in readings, which arise for several reasons, could in part explain ‘happy hypoxia’
