What is the Pulse oximeter.
Pulse oximeter is a painless and non-invasive test that determines your oxygen saturation level or the amount of oxygen in your blood. It can detect even little variations in the efficiency with which oxygen is transported to the extremities furthest from the heart, such as the legs and arms.
A pulse oximeter is a small, clip-like device that is worn on a body portion such as the toes or earlobe. It’s usually worn on a finger and is frequently utilized in critical care settings like emergency rooms and hospitals. It may be used in the office by some clinicians, such as pulmonologists.
Uses and purposes
Pulse oximetry is a test that determines how well your heart pumps oxygen throughout your body.
It can be used to track the health of people suffering from any ailment that affects blood oxygen levels, especially in the hospital. These are some of the conditions:
- COPD stands for chronic obstructive pulmonary disease (COPD)
- pneumonia asthma
- Anemia due to lung cancer
- heart failure or a heart attack
- cardiac abnormalities that are present at birth
- Pulse oximetry is used in a variety of situations, including the following:
- to see how well a new lung medicine is functioning and whether or not someone requires assistance breathing
- to determine how effective a ventilator is especially when treatment is new
How it works?
During a pulse oximetry reading, a little clamp-like device is placed on a finger, earlobe, or toe. Little beams of light flowing through the blood measure the amount of oxygen in the finger. It does so by detecting light absorption differences in oxygenated and deoxygenated blood. This is a straightforward technique.
As a result, the pulse oximeter can tell you your heart rate as well as your oxygen saturation levels.
Steps in the procedure.
Both inpatient and outpatient settings can benefit from pulse oximetry. Your doctor may recommend that you get a pulse oximeter for home usage in some instances.
The following is how pulse oximetry works:
- A clip-like device will presumably be attached to your finger, earlobe, or toe. A tiny amount of pressure may be felt, but there is no discomfort or pinching. A little probe with a sticky adhesive may be placed on your finger or forehead in some situations. If your fingernail polish is stuck to a finger, you may be requested to remove it.
- To monitor your pulse and oxygen saturation, you’ll keep the probe on for as long as you need it. This will be done during the duration of the workout and throughout the recovery interval when measuring physical activity capacities. The probe will be attached before surgery and will be removed once you are awake and no longer under monitoring. It may only be used to take a single reading rapidly at times.
- The clip or probe will be removed once the test is completed.
Readings from a pulse oximeter.
Pulse oximetry is a fairly accurate test in most cases. This is especially true when working with high-quality technology like that found in most medical offices and hospitals. It routinely produces results that are within a 2-percent range of what it truly is. Your true oxygen saturation level could be anything between 80 and 84 percent of your result was 82 percent. However, the waveform’s quality and the individual’s judgment must be taken into account. Movement, temperature, and nail polish can all affect accuracy.
More than 89 percent of your blood should be carrying oxygen in most cases. This is the oxygen saturation level that your cells — and your body — require to stay healthy. While having an oxygen saturation below this level for a short period of time is unlikely to cause harm, repeated or consistent low oxygen saturation levels may be harmful.
For most healthy people, and oxygen saturation level of 95% is considered normal. A score of 92 percent indicates possible hypoxemia or a lack of oxygen to bodily tissues.
So, what’s next?
When the test is finished, your healthcare professional will have the results available right away. This will aid them in determining whether additional testing or treatment is required. If you’re assessing the effectiveness of your oxygen supplementation therapy, for example, a reading that’s still on the low side could indicate that additional oxygen is needed.
Your healthcare practitioner will be able to advise you on what to do next. They’ll tell you how often to take your readings and what to do if they go over or below particular ranges if you’re using pulse oximetry at home.

Can an Oximeter Help Detect COVID-19 at Home?
An oximeter is a device that measures the amount of oxygen in the blood. If you have a lung or heart problem, you can use one at home to keep track of your progress. Perhaps you’ve had one clipped to your finger while in the ER or in the hospital.
Regardless of your previous experience with pulse oximeters, you may have noticed that they’ve been appearing in the news and on social media recently, in conversations with friends and family, and, if you’re like me, on your CVS receipt stuffed with coupons — all due of COVID-19.
Dr. Tim Connolly, a pulmonologist at the Cleveland Clinic, gave us the lowdown on pulse oximeters and if they may genuinely assist detect COVID-19.
