A pulse oximeter is a small medical device that measures the oxygen saturation (SpO₂) level in your blood and your pulse rate (PR). It is usually clipped on the fingertip, and within a few seconds, it shows your oxygen level and heart rate on the screen.

🔹 Normal SpO₂ value: 95% – 100%
🔹 Low SpO₂ (below 90%) may indicate a serious medical condition.

✅ Uses of Pulse Oximeter:

To monitor patients with asthma, COPD, pneumonia

To check oxygen levels in COVID-19 patients

During anesthesia and post-surgery recovery

For athletes and people at high altitudes


⚠️ Things to Remember:

Nail polish, cold fingers, or too much movement can affect accuracy.

It’s a monitoring device, not a replacement for medical diagnosis.


👉 A pulse oximeter is simple, fast, and very useful for both home and hospital use.
