HOW TO USE YOUR PULSE OXIMETER
What is SPO2 mean
A normal healthy person should be able to achieve normal blood oxygen saturation levels (SpO2) of 94% to 99%. For patients with mild respiratory diseases, the SpO2 should be 90% or above. Supplementary oxygen should be used if SpO2 level falls below 90%, which is unacceptable for a prolonged period of time.
Your pulse is your heart rate, or the number of times your heart beats in one minute. Pulse rates vary from person to person. Your pulse is lower when you are at rest and increases when you exercise (more oxygen-rich blood is needed by the body when you exercise). Most people the regular pulse rate is 60 beats a minute. however if the pulse rate drops to 50 beats/Min or less than this is known as bradycardia.
The main symptom of bradycardia is a heart rate below 60 beats per minute. This abnormally low heart rate can cause the brain and other organs to become oxygen-deprived, which can lead to symptoms such as:
- Shortness of breath
- Chest pain
- Memory difficulties
- Quickly tiring during physical activity
