Pulse oximetry in general practice: How would a pulse oximeter influence patient management?

Abstract

The pulse oximeter is a vital piece of equipment in secondary care for the non-invasive monitoring of oxygen saturation. With the increasing affordability of the oximeter and recognition of its clinical applications, there is an increasing interest in its role in primary care. The decision was made that a systematic review was not feasible due to the lack of data concerning the influence of pulse oximetry on patient management and on the extent of oximetry use in the general practice setting. In this article, a selection of studies is presented looking into its clinical use and limitations. The role and potential of the oximeter as a screening tool and aid in the assessment of hypoxia in a variety of clinical situations in primary care is discussed.
