The medical device measure SpO2 in the range of 70%–99% with the accuracy of ±2%. The normal resting pulse rate in humans is between 60 and 100 beats per minute (bpm), but it is also dependent on the fitness level, body weight, emotional state, medication, body position, and involvement in physical activities.
What causes a fast pulse rate?
If your heart rate is over 100 beats per minute when you are at rest, this is considered fast.
A rapid heart rate, also known as tachycardia, can be related to many different health conditions. It’s normal for your heart rate to increase when you’re exercising or if your body is fighting off an infection.
If you have noticed a sudden increase in your heart rate and are also feeling dizzy, faint, or having palpitations (a feeling of being aware of your heartbeat, or that your heart is pounding or beating irregularly), you should speak with your GP.
As per the studies, your right hand’s middle finger shows the best results. Make sure to take off any nail polish and avoid using cold fingers as the readings may not show correctly.
The term PRBPM refers to pulse rate (PR) and beats per minute (BPM) and the serious question is what PR and BPM mean on a pulse oximeter.
Human beings depend on oxygen for life. All organs require oxygen for metabolism but the brain and heart are particularly sensitive to a lack of oxygen.
