What is a Pulse Oximeter?
A pulse oximeter is a small, handheld device that measures the amount of oxygen in your blood. It is a non-invasive device that uses light to measure the absorption of oxygen by your hemoglobin. This measurement is known as your oxygen saturation level.
Why is it Important to Use a Pulse Oximeter?
Your oxygen saturation level is an important indicator of your overall health. A healthy oxygen saturation level is typically between 95% and 100%. If your oxygen saturation level drops below 90%, it is a sign that you may not be getting enough oxygen to your body. This can be a serious condition, and you should seek medical attention immediately.
How to Use a Pulse Oximeter
To use a pulse oximeter, follow these steps:
- Wash your hands and the finger you will be using.
- Place the pulse oximeter on your finger. The device should be snug, but not too tight.
- Wait a few seconds for the device to take a reading.
- Read the display. The display will show your oxygen saturation level and your pulse rate.
What Do the Results Mean?
A healthy oxygen saturation level is typically between 95% and 100%. If your oxygen saturation level is below 90%, it may be a sign that you are not getting enough oxygen to your body. This can be a serious condition, and you should seek medical attention immediately.
