Why We All Need a Pulse Ox

What is a Pulse Oximeter?

A pulse oximeter is a small device that measures the amount of oxygen in your blood. It works by shining a light through your finger and measuring how much light is absorbed by your blood. Oxygenated blood absorbs more light than deoxygenated blood, so a pulse oximeter can estimate the amount of oxygen in your blood by measuring how much light is absorbed.

Pulse Oximeters Can Detect Problems Early

Pulse oximeters can detect problems early, before you start to feel symptoms. This can be especially important for conditions like COPD and asthma, which can cause low blood oxygen levels. A pulse oximeter can also help you track your progress if you're being treated for a condition that affects your blood oxygen levels.

Pulse Oximeters Are Affordable

Pulse oximeters are relatively inexpensive, and they're available without a prescription. This makes them a great option for people who want to monitor their blood oxygen levels at home.

How to Use a Pulse Oximeter

Pulse oximeters are easy to use. Here are the steps:

1. Wash your hands and the finger you'll be using.

2. Place the pulse oximeter on your finger.

3. Make sure the light is shining through your finger.

4. Press the button to turn on the pulse oximeter.

5. Wait for the pulse oximeter to display your blood oxygen level.

What to Do if Your Blood Oxygen Level is Low

If your blood oxygen level is below 92%, you should see your doctor right away. This could be a sign of a serious medical condition.
