Recommended oximeters in Hong Kong in 2022｜Choose an oximeter｜Cardio oxygen concentration
Detecting blood oxygen concentration is actually detecting health warning signs. Early detection of hidden diseases can lead to timely treatment.
If you want to protect the health of yourself and your family, you must pay attention to your blood oxygen concentration and pulse.
So how should we choose the right oximeter product? Le Qi’s peers have compiled 4 major purchase guides for you, so that you can choose an oximeter more clearly.
Contents: Guide to Purchasing an Oximeter
1. Principle of oximeter
Oximeter, also known as blood oxygen saturation meter and blood oxygen measuring machine, is a non-invasive, non-invasive medical equipment.
The finger clip probe alternately emits infrared and red light, detects the absorption rate of different wavelength beams, and calculates the ratio of oxygenated hemoglobin.
The oximeter can quickly measure the user's blood oxygen saturation, pulse rate and other physical data for the user to evaluate the health status in real time.
2. Little knowledge of blood oxygen concentration
Oxygen saturation refers to the ratio of oxygenated hemoglobin to total hemoglobin in the blood, and is an important physiological indicator in the respiratory cycle.
Blood Oxygen Levels of Different People
| related person | blood oxygen content |
|---|---|
| healthy person |
The ideal blood oxygen level is about 99%-100%
|
| Obese and sub-healthy people |
The blood oxygen level drops to 97%-98%, and there are certain differences depending on the individual's physique and environment.

Blood oxygen saturation index reference
The following is the blood oxygen saturation index reference:
| Test results | health condition | Proposal |
|---|---|---|
| More than 98% | normal | Do not exercise vigorously |
| 94%-98% | mild hypoxia | intermittent oxygen supplementation |
| Below 94% | severe hypoxia | continuous oxygenation |
Low blood oxygen saturation can easily lead to shortness of breath, physical fatigue and other symptoms, and too low blood oxygen saturation can damage organ functions.
It has been reported that some foreign COVID-19 patients have a state of silent hypoxia (Silent Hypoxia). Although there are no obvious symptoms in the early stage of diagnosis, the body organs have been damaged to varying degrees, and the condition deteriorates rapidly afterwards.
It can be seen that the blood oxygen saturation value is closely related to physical health and can directly reflect health warning signs. For long-term patients and the elderly, using an oximeter to measure blood oxygen saturation can help detect changes in physical conditions and seek medical advice early.
3. 4 major purchase guides for oximeters
1. Automatic intelligent detection
Choose an oximeter with intelligent detection function for more convenient operation.
Some oximeters are equipped with automatic probes, which can be used to detect blood oxygen levels by simply clipping your finger. Even the elderly who are not familiar with using electronic devices can easily learn how to use it once they get started.
2. Abnormal alarm function
Monitoring body data is precisely to detect warning signs in advance, and an oximeter with an alarm function is more convenient.
Some oximeters can adjust the alarm range suitable for individual physical conditions. Once the value is abnormal, the oximeter can trigger an alarm to remind the user to monitor again or seek medical advice immediately.
3. Strong anti-interference performance
Users who are worried about accuracy are advised to purchase products with strong anti-interference performance.
Strengthen the resistance to interference from ambient light sources and electromagnetics, and avoid the influence of various external factors to ensure accurate detection results. Avoid excessive data errors, causing users to have many health concerns.
4. The display screen is clear enough
The most common finger-type oximeter has a light body and a relatively small screen. It is recommended to purchase an oximeter with a clear display.
After all, many users are elderly people, and the display screen is concise and clear enough to facilitate their understanding of their own health conditions. In addition, some oximeters can automatically sense, and can switch the screen to four directions, which is convenient for users to display detection results from different angles.

To protect the health of yourself and your family during the epidemic, you must pay attention to blood oxygen concentration and pulse status
4. Precautions for oximeter
- The finger is too cold to display the value, rub the end of the finger to promote blood circulation, and then measure again.
- If the finger is wet and the value cannot be displayed, you can dry your finger and measure again.
- Fingers with nail polish or artificial nails need to be removed before measurement can be performed.
- If you cannot measure many times, you can change other fingers to measure, but please avoid using your thumb.
- Please avoid shaking your hand and keep still for measurement.
