Which pulse oximeter is best to buy?
In general, in the brand rankings of the oximeter industry, well-known brands such as Olympic Medical, B. Braun Medical, Medtronic, Omron and Philips have certain advantages in product quality, technological innovation, market share, etc., and are favored by users. They're widely recognized and praised.
Which finger should I use to measure the blood oxygen saturation?
Clip the finger pulse oximeter on your finger with the display facing up. The index finger, middle finger and ring finger are most commonly used. These fingers may be relatively sensitive and have higher accuracy. The thumb and little finger are relatively wide and too small, respectively, so they may be slightly less sensitive than the other three fingers.
What data is displayed on the oximeter?
SpO2 stands for blood oxygen saturation.
The normal blood oxygen saturation of the human body is between 95% and 100%. The "PRbpm" on the oximeter shows the pulse rate, that is, the number of pulse beats per minute. Under normal circumstances, the pulse rate is 60 to 100 beats per minute.
When you're using the pulse oximeter, pay attention to these three issues.
- Instrument problems: Make sure the instrument is in good condition before use.
- Nails: Blue nail polish has the greatest impact, followed by green and black, and red nail polish has no impact. Gray nails will also have a certain impact on the accuracy of blood oxygen saturation monitoring.So please make sure there is no nail polish on your nails when using it
- Movement interference: Finger shaking will also cause certain effects, so you have to wait a few seconds for the pulse waveform to stabilize. The reading will be more accurate.
How does the fingertip pulse oximeter work?
Two beams of light (one red light and one infrared light) are used to illuminate and penetrate the fingers. The absorption of these lights differs significantly between oxygenated blood and oxygen-deprived blood. Blood full of oxygen absorbs more infrared light, allowing more red light to pass through. Blood with insufficient oxygen absorbs more red light and allows more infrared light to pass through.
