Step 3

Select the appropriate site to apply the sensor by assessing capillary refill in the patient’s toe or finger. This is done by applying pressure to the nail bed until it turns white, then releasing the pressure and watching for the return of blood flow. The pink color should return in less than 2 seconds.

Step 12

Rotate the patient’s finger sites every 4 hours if using a pulse oximeter long-term.

Step 4

Drop the object directly into an approved puncture-proof container for sharps. Engage safety device, if indicated.

Step 10

Manually check the patient’s pulse and compare it to the pulse oximeter. Document all the readings and the application site in the patient’s chart/progress note.

Step 2

Wash your hands and correctly identify the patient.

Step 1

Assemble all the necessary equipment and supplies.

Step 5

Attach the sensor to the site (if a finger is used, place it in the clip).

Step 11

Wash your hands.

Step 6

Instruct the patient to breathe normally.

Step 8

Set the alarm limits for high and low oxygen saturations and high and low pulse rates, as directed by the physician’s order.

Step 4

Prepare the selected site, removing nail polish or earrings if necessary. Wipe the selected site with alcohol and allow it to air-dry.

Step 9

Read the saturation level and document it. If the result is less than 90%, have the patient take a few deep breaths and then recheck. Document the highest result. Report to the physician readings that are less than 95%.

step 7

Attach the sensor cable to the oximeter. Turn on the oximeter and listen to the tone if required.
