Pulse Oximetry is a non-invasive and painless test that measures the oxygen saturation level in the blood and it can be used as a simple self administered test. It can rapidly detect even small changes in how efficiently oxygen is getting into the blood in the lungs and being carried to all parts of the body. Minor reduction in lung function due to infections, COPD, Asthma, Bronchitis or any other lung disorders can be picked up early on by the measurement of oxygen saturation on the blood using the fingertip pulse oximeter.
Features of fingertip pulse oximeter:
Once the test is over, your care provider will have the readings available immediately. This will help them determine if other testing or treatment is necessary.
What is a normal reading on a pulse oximeter?
Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg).
What are the 2 readings on a pulse oximeter?
The 2 readings on a pulse oximeter are:
How does this work?
During a pulse oximetry reading, a small clamp-like device is placed on a finger. A small beam of light passes through the blood in the finger, measuring the amount of oxygen. It does this by measuring changes of light absorption in oxygenated or deoxygenated blood. This is a painless process.
How do pulse oximeter help during Covid-19 and do I need one?
When it is hard to assess why there is difficulty in breathing, this device can help early detection of COVID-19 symptoms (if any). It can identify any irregularities in the oxygen flow. It is best to always keep one at home to check whenever required.
NOTE: Low oxygen level Does Not always mean it is due to COVID-19. Consult your doctor at the earliest.
