What is pulse oximetry?

A pulse oximeter is a test used to measure the level of oxygen in the blood (oxygen saturation). It is an easy and painless measurement of how well oxygen is being delivered to the parts of the body furthest from the heart, such as the arms and legs.

A clip-like device called a probe is placed on a part of the body, such as a finger or an earlobe. The probe uses light to measure the amount of oxygen in the blood. This information helps the healthcare provider decide whether or not the person needs supplemental oxygen.

Why do you need a pulse oximeter?

A pulse oximeter can be used to make sure there is enough oxygen in the blood. This information is needed in many cases. It may be used.

• After use or after use
• Make sure that the lungs work

• To see how well the fan is or how well it works
• When breathing stops during sleep, make sure that there is a person's time (sleep apnea)
• For example, pulse discipline is used to control human health. For example, it affects the level of oxygen in the blood.
• heart
• Heart failure
• Chronic obstructive pulmonary disease (COPD)

Pneumonia

Care techniques may have other reasons to advise pulse oximeters.

What are the risks of pulse oximetry?

All procedures involve some risk. Risks from this procedure may include:

• If the probe is on the tip of the ear, finger, or toe, it is a false reading.
• Skin irritation from the adhesive on the probe
• Your risk may vary depending on your overall health and other factors. Ask your healthcare provider what risk is best for you. Talk to him if you have any concerns.

How to prepare for pulse oximetry?

Your doctor will explain the procedure to you. Ask any questions you have about the process. If you use a finger probe, you may be asked to remove the nail polish.

Your healthcare provider may give you other instructions to help you prepare.

What happens during pulse oximetry?

The procedure can be performed on an outpatient basis. It means that one day you will go home. Or it can be done as part of a long hospital stay. Procedures may vary. It depends on your condition and your doctor's method. In most cases, a pulse oximeter follows this process:

A clip-like device called a probe is placed on your finger or earlobe. Alternatively, you can place the probe on your forehead or fingers with a sticky adhesive. The probe can be turned on for continuous monitoring.

Or you can use it to get a size. After testing, the probe is removed.

What happens after pulse oximetry?

If you are not hospitalized for other reasons, you can go home after the test. You can resume your regular diet and activities as directed by your healthcare provider. At the end of the procedure, your doctor may give you further instructions.
