Introduction (what is the pulse oximeter)[edit | edit source]
A Pulse Oximeter is a handheld device used to measure one's oxygen saturation. Pulse Oximetry is the process of using the device to measure the oxygen saturation.
Due to its portability, it can easily be used at rest, and can also be used during exercise.
The Device[edit | edit source]
The pulse oximeter is a gentle clamp, which provide two digital readings: your heart rate, and oxygen saturation. [1]
It is placed around the fingertip, and the outputs are displayed within seconds. The device consists of a cold light source which shines a light through the fingertip. The device analyzes the light that is passing through the fingertip, and will determine the percentage of oxygen in the red blood cell. [1]
This is a non-invasive device, and does not involve any pain discomfort to administer. [1] This can be seen in the picture of the device, on the right.
Procedures (for using the pulse oximeter)[edit | edit source]
The device can be used on the fingers, ears, nose, or toes. [1]
Contraindications, conditions, and limitations, risks[edit | edit source]
There are many factors which may cause an inaccurate or unreliable reading. Such factors may include:
- Poor Circulation [1]
- Cool skin temperature [1]
- Have dark nail-polish [1]
- Long nails or unclean nails [1]
- Tobacco usage [1]
- Dark skin pigmentation [1]
There are no risks or dangers of having the device administered. [1]
