@2024_Peripheral Oxygen Saturation Measurement and Electrocardiogram Monitor Connection (Pulse Oximeter and EKG Monitor) 1) Meaning of Oxygen Saturation : Oxygen saturation refers to the percentage of hemoglobin containing O2 out of total hemoglobin. The normal range is 95-100%. 2) Factors Affecting Oxygen Saturation (1) Hemoglobin Even if oxygen saturation levels return to normal, if the subject is severely anemic, oxygen delivery to tissues may be inadequate. (2) Circulation Accurate measurements cannot be obtained if the sensor is attached to an area with poor circulation, such as cold or pale skin. (3) Activity Trembling or excessive movement at the sensor attachment site can interfere with accurate measurements. Compare the pulse rate on the monitor with the subject's heart rate. (4) Carbon monoxide poisoning - When hemoglobin is saturated with oxygen and carbon monoxide, it cannot distinguish between the two. ★When selecting the most appropriate site for attaching the sensor • Select a dry area with adequate peripheral circulation. • Remove nail polish or artificial nails. • If the subject exhibits tremors or significant movement, attach the sensor to the earlobe. • If the finger is hypothermic, circulatory insufficiency, or has a history of vascular disease, do not attach the sensor to the finger; instead, select the ear or tip of the nose. • Do not attach the sensor to an arm with an automatic blood pressure cuff.
