A pulse oximeter is a small electronic device that estimates the saturation of oxygen in your blood. The normal range is 95% to 100%. Hypoxemia is inferred when the oxygen saturation levels are 92% or below. That's a cause for concern. That's generally the level where a doctor might put you on supplementary oxygen and keep you in the hospital for observation.
Suitable for people prone to hypoxia:
1. Outdoor athletes (during a long-time vigorous exercise or altitude sickness can cause dizziness, rapid heartbeat, or other diseases due to lack of oxygen.)
2. Women in pregnancy (Hypoxia will affect the baby's intelligence, in order to welcome a new life, please pay attention to blood oxygen.)
3. The elderly (old heart and lung function, easy to lack of oxygen.)
4. The sick (COVID-19 patients, patients with heart disease and high blood pressure, poor blood flow, poor oxygen supply, and easily lead to insufficient oxygen.)
You need an oximeter to always pay attention to your blood oxygenation and your health.
It has the advantages of small size, low power consumption, easy operation, and easily carrying.
How to measure
As long as the finger is put into it, the medical device collects data through a photosensitive detector and then displays the measurement result on the indicator.
