Abstract
Pulse oximetry is widely used to non-invasively estimate the oxygen saturation of haemoglobin in arterial blood (SpO2). It is used widely throughout healthcare and was used extensively during the Covid-19 pandemic to detect and treat hypoxic patients. Research has suggested that pulse oximetry is less accurate in patients with darker skin. This led the US Food and Drug Administration agency (FDA) to issue a safety statement warning that pulse oximeters may be inaccurate when patients have pigmented skin.
Evidence suggests that the oxygen saturation of arterial blood (SaO2) may be being overestimated by measuring SpO2 in those with pigmented skin. The degree of overestimation increases as SaO2 decreases especially when SpO2 reads below 80%. We review how pulse oximetry works and consider the implications for a patient’s health when interpreting SpO2 in individuals with pigmented skin.
期刊介绍：
Paediatric Respiratory Reviews offers authors the opportunity to submit their own editorials, educational reviews and short communications on topics relevant to paediatric respiratory medicine. These peer reviewed contributions will complement the commissioned reviews which will continue to form an integral part of the journal.
Subjects covered include:
• Epidemiology
• Immunology and cell biology
• Physiology
• Occupational disorders
• The role of allergens and pollutants
A particular emphasis is given to the recommendation of "best practice" for primary care physicians and paediatricians.
Paediatric Respiratory Reviews is aimed at general paediatricians but it should also be read by specialist paediatric physicians and nurses, respiratory physicians and general practitioners.
It is a journal for those who are busy and do not have time to read systematically through literature, but who need to stay up to date in the field of paediatric respiratory and sleep medicine.
