Monitoring your blood oxygen at home has never been more important—especially for people with chronic respiratory conditions, high-altitude travelers, athletes, and the elderly. But what exactly is a pulse oximeter, and how does it work?
What Is a Pulse Oximeter?
A pulse oximeter is a small and portable, non-invasive medical device that measures the oxygen saturation in your blood. In simpler terms, it tells you how well oxygen is being delivered to the parts of your body furthest from your heart—like your fingers and toes.
Most pulse oximeters are fingertip devices, designed to clip onto your finger and provide a quick reading within seconds.
How Does It Work?
Pulse oximeters use light-based technology to measure oxygen levels. Here's how:
- The device emits red and infrared light through your fingertip.
- Oxygen-rich and oxygen-poor blood absorb light differently.
- A sensor detects the amount of light passing through and calculates your oxygen saturation percentage—typically shown as SpO₂.
A healthy SpO₂ reading is usually between 95% and 100%. If your readings fall below this range, especially without symptoms, you could be experiencing “silent hypoxia”, which may require medical attention.
Why Is a Pulse Oximeter Useful?
- Tracking your blood oxygen levels in real time
- Monitoring your pulse rate
- Detecting early signs of respiratory issues
- Helping in COVID-19 recovery and high-altitude acclimatization
Why Choose a Medical-Grade Oximeter Like MEDLINKET AM801?
While many fingertip oximeters are available online, not all offer clinical accuracy. The MEDLINKET AM801 is a medical-grade, FDA and CE certified pulse oximeter designed for:
✔️ Reliable readings even at low perfusion levels (0.1% PI)
✔️ 3-in-1 monitoring: SpO₂, pulse rate, and body temperature
✔️ Clinically validated accuracy to avoid false "normal" readings
✔️ Flashing alerts for abnormal results
Whether you're monitoring a loved one or your own health, the AM801 provides professional-level precision in a compact, easy-to-use device.
