Pulse oximetry: an audit of nursing and medical staff understanding.
Pulse oximetry provides continuous, non-invasive monitoring of the oxygen saturation of haemoglobin in arterial blood, which is updated with each pulse wave. The primary advantage is that it detects immediately deviations to a patient's baseline. Care givers can therefore detect changes before the patient becomes hypoxaemic. However, staff are reported to have limited education, if any, in the correct use of the pulse oximeter and what may affect the readings. In order to test this theory, an audit was conducted on 50 staff within a large general hospital, comprising trained and untrained nurses and medical staff. Participants' responses to a questionnaire and to six clinical scenarios were analysed. Overall, there was a deficit in participants' knowledge on pulse oximetry. The answers given by the medical staff to the clinical scenarios showed no greater level of knowledge than many of the trained nurses. The recommendations made following this audit were to improve the education and training of all staff in the understanding of this technique.
