2022 Hong Kong Pulse Oximeter Recommendations | Choosing a Pulse Oximeter | Blood Oxygen Levels
Monitoring blood oxygen levels is essentially monitoring for health warning signs. Detecting underlying conditions early allows for timely treatment.
To safeguard your and your family's health, it is essential to pay close attention to blood oxygen levels and pulse status.
So how should we choose a suitable pulse oximeter? Lohas Elderly has compiled 4 major purchasing guides to help everyone choose a pulse oximeter more clearly.
Table of Contents: Pulse Oximeter Purchasing Guide
1. Pulse Oximeter Principles
A pulse oximeter, also known as a blood oxygen saturation meter or blood oxygen monitor, is a non-invasive medical device.
It uses a finger clip probe to alternately emit infrared and red light, detects the absorption rate of light beams at different wavelengths, and calculates the proportion of oxygenated hemoglobin.
A pulse oximeter can quickly measure the user's blood oxygen saturation, pulse rate, and other physiological data, allowing users to assess their health status in real time.
2. Blood Oxygen Level Facts
Blood oxygen saturation (Oxygen saturation) refers to the ratio of oxygenated hemoglobin to total hemoglobin in the blood, which is an important physiological indicator of respiration and circulation.
Blood Oxygen Levels for Different People
| Relevant Individuals | Blood Oxygen Level |
|---|---|
| Healthy Individuals |
Ideal blood oxygen level is approximately 99%-100%
|
| Obese and Sub-Healthy Individuals |
Blood oxygen levels fall to 97%-98%, with certain differences depending on individual constitution and environment.

Blood Oxygen Saturation Reference
The following is the blood oxygen saturation reference:
| Test Result | Physical Condition | Recommended Action |
|---|---|---|
| Above 98% | Normal | Avoid strenuous exercise |
| 94%-98% | Mild Hypoxia | Intermittent Oxygen Supplementation |
| Below 94% | Severe Hypoxia | Continuous Oxygen Supplementation |
Low blood oxygen saturation can easily lead to symptoms such as shortness of breath and fatigue, while extremely low blood oxygen saturation will further damage organ function.
Reports indicate that some COVID-19 patients experience silent hypoxia, where there are no obvious symptoms in the early stages of diagnosis, but their organs have already sustained varying degrees of damage, followed by a rapid deterioration of their condition.
It is evident that blood oxygen saturation levels are closely related to physical health and can directly reflect health warning signs. For long-term patients and elderly individuals, using a pulse oximeter to measure blood oxygen saturation can help detect changes in physical condition and seek medical attention early.
3. 4 Major Pulse Oximeter Purchasing Guides
1. Automatic Intelligent Detection
Choosing a pulse oximeter with intelligent detection makes operation more convenient.
Some pulse oximeters feature an automatic probe that can be directly clipped onto a finger to measure blood oxygen levels. Even elderly individuals who are unfamiliar with using electronic devices can easily learn how to use it upon first use.
2. Abnormal Alarm Function
Monitoring physiological data is precisely for detecting warning signs early, so a pulse oximeter with an alarm function is even more convenient.
Some pulse oximeters allow users to adjust the alarm range to suit their individual physical condition. Once the value shows an abnormal situation, the pulse oximeter can trigger an alarm to remind the user to monitor again or seek medical attention immediately.
3. Strong Anti-Interference Performance
Users concerned about accuracy are advised to choose a product with strong anti-interference performance.
Enhance resistance to interference from environmental light sources and electromagnetic fields, eliminate the influence of various external factors, and ensure accurate detection results. Avoid causing users serious health concerns due to excessive data errors.
4. Clear Display Screen
The most common finger pulse oximeters have compact bodies, and their screens are relatively small, so it is recommended to choose a pulse oximeter with a clear display screen.
After all, many users are elderly individuals, and a sufficiently simple and clear display can help them understand their health status. In addition, some pulse oximeters can automatically detect and switch the display in four directions, allowing users to view the detection results from different angles.

- If the finger is too cold, the device may not display a reading. Rub the fingertip to promote blood circulation before measuring again.
- If the finger is damp, the device may not display a reading. Wipe the finger dry before measuring again.
- Remove nail polish or artificial nails before measuring.
- If you cannot get a reading after several attempts, try using a different finger, but avoid using your thumb.
- Avoid shaking your hand and keep it still while measuring.
