SpO2 Monitoring

NOTE

SpO2 Monitoring

A pulse oximeter is a noninvasive device that indicates the oxygen saturation (SpO2) of arterial blood. This measurement is obtained through a probe that directs red and near infrared light through arterial beds. Hemoglobin absorbs these lights differently when it is bound with oxygen. Pulse oximetry mea- sures this difference and translates the measurement into a saturation percent- age that is displayed as an SpO2 reading.

Indications

SpO2 monitoring is indicated for use when it is beneficial to assess a patient’s oxygen saturation level.

Contraindications

None known.

Readings should be carefully considered in the presence of certain circum- stances. Inaccuracies may result from the use of pulse oximeters in the pres- ence of certain circumstances, such as hemoglobin saturated with compounds other than oxygen (such as carbon monoxide), hypothermia, hypovolemia, patient movement, nail polish and excessive ambient light.
