A Pulse Oximeter is a small device which measures with high accuracy the oxygen concentration in your blood as well as your heart rate, both of which are essential factors when it comes to analyzing your heart health. This device shows you how efficient your lungs are at extracting oxygen from the air you breathe in.
Using the device is quite easy, all you need to do is, clip the device into peripheral areas like your finger, toe or the ear where the skin is thin so that the device can painlessly measure the Peripheral Oxygen Saturation which is shown on the device as SpO2. And the bottom line of this device shows how well your lungs are working to pump oxygen in your blood through your body.
As we all know, COVID 19 virus affects our lungs the most. This has a direct bearing on the oxygen concentration in our blood. The infection causes our lungs to be filled with fluids and pus which makes it difficult to breathe, a condition known as COVID-pneumonia. Thus an oximeter can help by confirming the SpO2 levels, thereby helping in early detection and treatment of COVID pneumonia. Yet another example would be to detect COVID with mild symptoms like fever and cough before the breathlessness sets in.  Other than that if you are a trekker or adventure lover you can use this device while trekking at high altitude when the oxygen concentration is less. This device will help you track the oxygen saturation and to see how well your body is responding to the environment. Adding to that it can also find out if you have any undetected heart issues.

The pulse oximeter can be used on a daily basis to check your health condition. To check a person’s oxygen saturation with increased physical activity. Or if someone is taking lung medication or in ventilator to check if it is working properly or to check if a person has sleep apnea.

A pulse oximeter is a compact device and some of these devices even come with an alarm that will switch on and off the device as per your needs and ensure that you do not miss checking.
