Pulse oximeter is a small device that usually slides over your fingertip or clips on your ear lobe and uses infrared light refraction to measure oxygen level in your body.


Know your pulse rate and also the amount of oxygen saturation or oxygen level in your blood by using pulse oximeters. These devices help display the percentage of oxygen in your bloodstream and also your current pulse rate in a painless and non-invasive manner. With this handy medical device in your home, you don’t need to go to a clinic or a hospital to check your pulse rate or oxygen levels. These smart medical devices display the readings in a short amount of time, making it perfect for use by healthy individuals as well as people who are suffering from conditions such as chronic obstructive pulmonary disease (COPD), asthma, pneumonia, lung cancer, anemia, corona etc. The normal oxygen saturation (SpO2) level of a healthy individual should be 95% or greater. These devices use SpO2 sensors to determine the percentage of oxygen that’s in your blood. The pulse rate refers to the number of times your heart contracts in a minute. The normal pulse rate of a healthy adult ranges from 60-100 beats per minute (bpm). You can buy the best pulse oximeters online from some of the reputed brands, such as Dr. Trust (USA), Control D, iSpares, OxiPlus, Levelert, and many more.


What are the Pulse Oximeters?
A pulse oximeter is nothing but a device that rapidly detects changes in your blood oxygen level. Pulse oximeters are easy to use. The sensors in the device detect and calculate the percentage of oxygen in your blood based on the way light passes through your finger. 
Apart from this, pulse oximeters are also very helpful in fitness monitoring, letting you know your limits so you don’t push yourself to the point of your blood running out of oxygen.

Oximeters are not just meant for people suffering from chronic diseases. This device shows you readings which you can use to gauge your overall fitness. Trekking requires you to have good stamina. This is especially the case for moderate- to difficult-level treks, such as the Himalayan treks. You can assess your fitness quotient and then see if you are healthy enough to undertake a trek at such high altitudes. It is imperative to monitor your health before and during such treks.

Choosing the Type of Pulse Oximeter
You can shop for pulse oximeters online to find them available in different types. There are pulse oximeters designed to be worn on the finger, strapped around the wrist, placed and used on tabletops and even pulse oximeters that are designed to be handheld.

If yes, you can buy pulse oximeters that are designed to be worn on the finger. On the other hand, if you are looking for more accurate readings, handheld pulse oximeters are a better choice for you. Tabletop pulse oximeters are convenient for spot checks and continuous monitoring. 
The Display
The display is another very important feature that you may want to consider when you buy pulse oximeters online. If you want nothing less than a bright and clear view, you can shop for pulse oximeters that come with backlit displays. A few other things that you can consider here are font combinations, adjustable brightness to accommodate different lighting conditions and multiple viewing angles.
