Using Pulse Oximetry

What is the first step in preparing to use a pulse oximeter?

Review the patient's health record for any health problems affecting oxygenation. Gather equipment.

What should you do after gathering your equipment?

Perform hand hygiene and put on personal protective equipment (PPE), if indicated.

What is the next step after hand hygiene and PPE?

Identify the patient.

How should you prepare the patient and environment for using a pulse oximeter?

Assemble equipment on a bedside stand, close curtains, and explain the procedure to the patient.

What is the process for selecting the application site for the sensor?

Use the index, middle, or ring finger. Ensure circulation is adequate. Consider using the earlobe or forehead if circulation is poor.

What should you check when selecting equipment for a pulse oximeter?

Use the appropriate probe for the patient’s age/size. Ensure it fits correctly, check for allergies, and ensure the probe matches the site.

How should you prepare the skin for sensor placement?

Clean the area, remove nail polish or artificial nails if necessary, and allow the area to dry.

What should you check when attaching the sensor to the skin?

Ensure the light-emitting and light-receiving sensors are aligned (except on the forehead).

What should you do after attaching the sensor?

Connect the probe to the pulse oximeter, turn it on, and check the operation of the equipment.

What are the key steps for monitoring with the pulse oximeter?

Set alarm limits, check oxygen saturation at regular intervals, and monitor hemoglobin levels.

How often should you check for skin irritation or pressure?

Every 2 hours for spring-tension sensors and every 4 hours for adhesive sensors.

How should you clean the sensors?

Follow the manufacturer’s instructions for cleaning nondisposable sensors.

What is the final step after using the pulse oximeter?

Remove PPE, perform hand hygiene, and document the procedure.
