A pulse oximeter is an electronic device that helps to measure the level of oxygen in the blood. It is a simple, pain-free measuring instrument that checks how oxygen is delivered to other organs of the body which are far away from your heart. 

It also measures the rate of your heartbeat. If it indicates a rate for your heartbeats per minute between 60 to 100, it simply means your heartbeats are normal and don’t need to contact any doctor.

It is a clip-shaped tool known as a probe. It places on a body part, like a finger. for analyzing oxygen percentage in blood using lights. It provides information to help a doctor to decide whether a person needs extra oxygen or not.

When Should Pulse Oximeter Be Used?

There are many types of conditions for which you can use this device.  Examining oxygen levels is needed for various kinds of issues. 

• During the process of surgery or after completing the surgery. 
• Examining whether the lung medicines are working properly or not
• For analyzing human’s capability to control enhancing activity levels.
• To check if a ventilator is required for a person to help in breathing.

Pulse oximeter normal range:

A normal heart rate of a human is between  to 100 beats per minute. Before taking a reading it is good to keep in mind the normal range. It will help you to compare both readings. Similarly, before analyzing oxygen levels, you should know what is the normal rate of oxygen in the blood. The normal rate of oxygen in the blood is 95. If the oximeter shows you 95 or above 95, it means you are good. But if it demonstrates below 93 percent then you should contact your doctor.

What should i do if my oxygen level is not normal?

If the oximeter shows you a number that is 92 or lower, you should consult with your doctor. But don’t panic. A doctor will suggest a better treatment for this and you will clear up soon. If your oxygen level is lower than 88% you should take a daily treatment it can develop your health condition.

Symptoms of lower oxygen:

• Shortness of breath
• Rapid breathing 
• High blood pressure
• Lack of coordination
