Understanding your oxygen levels is helpful in understanding how your body works, but it is especially important for people living with breathing difficulties.

If you have breathing or heart problems, you may experience low blood oxygen levels, which can be dangerous if left untreated.

If you need to know if your oxygen levels are healthy, it is essential that you understand what a normal blood oxygen level is for you, as well as how to regulate your blood oxygen level when it drops.

Ever heard of a pulse oximeter? If you have a lung or heart condition, you may use one periodically at home to monitor your condition.

A finger pulse oximeter measures two things:
- Blood Oxygen Saturation (SpO2): The measurement that indicates what percentage of blood is saturated, and
- Pulse Rate: Pulse rate is nothing but the heart rate that indicates the number of times a heart beats per minute.

Read on to learn more about blood oxygen levels and how to know if you need to worry about yours.

How to read a pulse oximeter?

Normal oxygen saturation range
- Using red and infrared light sources and a light sensor, pulse oximeters determine the percentage of hemoglobin (red blood cells) in your bloodstream that carries oxygen to various parts of your body.
Normal pulse rate range
- Your blood is not stagnant in your veins. Therefore, it is almost impossible to synchronize a pulsed light with your heart rate to determine your blood oxygen saturation.
- Instead, a pulse oximeter uses a constant stream of light to measure absorption and a sophisticated calculation to measure “pulsed absorbance” while filtering interference from muscles, tissues, and nails.
- Since it only measures oxygen uptake during blood flow, it reads a pulse rate in addition to oxygen saturation.

How to check oxygen level at home?

It is important to know what your personal normal blood oxygen level is, and your doctor will be able to identify what is normal for you after performing a comprehensive exam and performing your blood oxygen level tests.

However, unless your doctor tells you to expect something different as a result of COPD or another health condition that could cause a lower-than-normal blood oxygen level, there are some general guidelines you should follow.

When it comes to your ABG oxygen level (PaO2), the normal reading is between 80 and 100 mm Hg.

A normal pulse oximeter (SpO2) measurement should be between 95 and 100 percent.

If your blood oxygen levels are below 75 mm Hg or below 90 percent, you must take steps to improve your blood oxygen level immediately.

What are the 2 readings on a pulse oximeter?

Blood Oxygen Saturation (SpO2): The measurement that indicates what percentage of blood is saturated, and Pulse Rate: Pulse rate is nothing but the heart rate that indicates the number of times a heart beats per minute.

Is an oxygen level of 94 bad?

Your blood oxygen level is measured as a percentage; 95 to 100 percent is considered normal. Low oxygen levels can be an early warning sign that medical attention is needed, and having a SpO2 reading below 94% is a warning and cause for concern.

How to work pulse oximeter?

If working accurately, you can expect a simple, quick, and safe measure of the oxygen saturation level in your body. The probe will be positioned and within a few seconds, the oximeter will provide a readout of your heart rate and your oxygen saturation level.
There are no needles and no pain involved in oximetry measurement. Some hospitals also use disposable tape probes that wrap around your finger, nose, or toe.

What is normal spo2 and pr bpm?

For most people, a normal oxygen level is 95% or higher and a normal heart rate is generally below 100. A normal resting heart rate for adults ranges from 60 to 100 beats per minute.
