What exactly does a pulse oximeter measure?
A pulse oximeter is a non-invasive device that measures two key vitals: your pulse rate (heart rate) and, most importantly, your oxygen saturation level in your blood (SpO2). This SpO2 reading is a percentage that estimates how much oxygen your red blood cells are carrying, which is a vital indicator of how well your lungs are working.
What is a "normal" SpO2 reading?
For most healthy individuals, a normal oxygen saturation level in your blood (SpO2) is between 95% and 100%. If you have a pre-existing condition, such as COPD or sleep apnea, your "normal" range might be lower. It is essential to speak with your healthcare provider to understand what your target range should be.
How can I get the most accurate reading?
To ensure the best oxygen saturation monitor performance, always be sure your hands are warm, as cold fingers can restrict blood flow and cause a faulty reading. You should rest for a few minutes before taking a measurement. Dark nail polish or artificial nails can also block the sensor, so it's best to use a clean finger.
What is the difference between all the models?
You will see many types of pulse oximeters available. Simple fingertip models are best for "spot-checking" your levels. Handheld or wrist-worn models are often used for continuous or overnight monitoring. The best oxygen saturation monitor for you depends entirely on your needs—whether it's for sports and wellness or for managing a clinical condition.
