Pulse oximetry can be used to see if there is enough oxygen in the blood. This information is necessary for many types of situations. It can be used:
- To see how well your lung medications are working
- To see if a ventilator is needed to help with breathing or to see how well it is working
- To check a person’s ability to handle higher levels of activity.
- To check that a person has moments when breathing stops during sleep.
What is a normal blood oxygen level?
What is a normal blood oxygen level and when should I be concerned?
If you are using a pulse oximeter to measure your blood oxygen level, a normal reading is an Sp02 level that is between 95 and 100 percent.
However, this can vary for people with certain medical conditions, such as lung disease.
Talk to your doctor to determine what is “normal” for you and note that while these home devices are practical and non-invasive, they are not always 100% accurate.
Other tests, performed by healthcare providers, include blood draws or breathing tests to accurately measure blood oxygen levels.
If your Sp02 is below 95%, you should check with your healthcare provider.
How to check pulse oximeter?
What happens during pulse oximetry?
You can have your procedure as an outpatient. This means that you will return home the same day. Or it can be done as part of a longer hospital stay. The way the procedure is performed can vary. It depends on your condition and the methods of your healthcare provider. In most cases, pulse oximetry will follow this process:
- A clip-like device called a probe will be placed on your finger or earlobe.
- Or, a sticky tube may be placed on your forehead or finger.
- The probe can be left on for continuous monitoring.
- Or it can be used to take a single reading. The probe will be removed after the test.
Basically, pulse oximetry is a painless, non-invasive method of measuring the saturation of oxygen in a person’s bloo
Oxygen saturation is a crucial measure of how well the lungs are working. When we breathe in air, our lungs transmit oxygen into tiny blood vessels called capillaries.
In turn, these capillaries send oxygen-rich blood to the heart, which then pumps it through arteries to the rest of the body. Our organs need a constant supply of oxygen to work properly.
Pulse Oximeters: Answering Your Frequently Asked Questions
As per the studies, your right hand’s middle finger shows the best results. Make sure to take off any nail polish and avoid using cold fingers as the readings may not show correctly.
During a pulse oximetry reading, a small clamp-like device is placed on a finger, earlobe, or toe. This is a painless process.
