When we think of vital signs, most people mention blood pressure, heart rate, or blood sugar. But there’s another critical number you should be monitoring — especially if you're over 40 — and that’s your oxygen saturation (SpO₂).
As a medical doctor with experience treating respiratory conditions, I can confidently say: a pulse oximeter is one of the most underrated yet essential tools you can keep at home.
A pulse oximeter is a small, clip-like device that painlessly attaches to your fingertip and instantly tells you:
Your oxygen saturation level (SpO₂)
Your pulse rate
It takes just a few seconds to get a reading — no needles, no mess.
Here’s why having your own oximeter is a smart move:
A drop in oxygen levels can indicate:
COVID-19 or flu complications
Sleep apnea
COPD or asthma flare-ups
Silent lung infections (especially in diabetics and seniors)
People with heart disease, lung conditions, or even long COVID benefit from regular oxygen monitoring — especially during physical activity or sleep.
Feel short of breath? A quick check on your oximeter can help you decide whether it’s anxiety or something more serious.
Adults over 40
Smokers or ex-smokers
People with asthma, COPD, or heart disease
Anyone recovering from respiratory infections
Athletes or fitness-focused individuals tracking oxygen during workouts
After testing several models and recommending them to patients, this is the one I trust:

It’s compact, fast, and comes with a clear digital display. Perfect for both home and travel.
I’ve seen patients avoid ER visits simply because they were able to catch a drop in their oxygen levels early. Having this device at home is not just about emergencies — it’s about empowering yourself with health data every day.
Investing in a pulse oximeter may seem minor — until the moment you really need it. For under the price of a dinner, you could have a lifesaving device at your fingertips.
