The blood oxygen level in the body (or oxygen saturation levels) is a measure of how much oxygen is present in the red blood cells.
Studies shows that maintaining a precise balance of oxygen-saturated blood is very important for good health. And this process of balancing is automated by your body in most of the cases.
However in patients suffering from health conditions such as chronic respiratory problems, asthma, COPD, heart disease, etc. the balancing of oxygen saturation levels in the blood gets altered.
Thus the levels oxygen saturation in such conditions needs to be monitored regularly for avoiding any serious problems.
Hypoxemia (blood oxygen levels below the normal) is a condition of concern for most of the patients.
In case you are suffering from serious lung conditions, it is important for you to know about the normal oxygen levels that are right for you. Also it is important that you maintain the same so as to avoid any serious consequences.

What Is A Pulse Oximeter?
Pulse oximetry is a non-invasive method by which a person’s oxygen saturation (SO2) can be monitored easily.
The small portable device which is used to detect rapid changes in your blood oxygen level is called as pulse oximeter.
In most cases, a Pulse Oximeter is used to measure two different things namely:
- Heart rate
- Oxygen saturation in blood
Getting count or details pertaining to heart rate is pretty easy with Pulse Oximeter. It works by picking the lub dub of heart and then translates this count on a display screen.
Reading an oxygen saturation level in your blood with Pulse Oximeter is the method of finding the percentage of hemoglobin molecules in arterial blood. This is the level of blood that then saturates with oxygen.
You can shine a light through your finger which then helps in calculating the level of oxygen with the help of sensor that are attached to Pulse Oximeter.
How Does It Work?
Pulse Oximeter works using a very simple principle, wherein it takes into account the method by which absorption of red and infra red lights occur.
This absorption is characterized by both oxygenated and deoxygenated haemoglobin in a human body.
In case of oxygenated haemoglobin, then it shall absorb infrared and allow red light to pass through, whereas in case of deoxygenated hemoglobin, then you could see absorption of more red light and allow infra red to pass through.
Pulse Oximeter Types
While oximetry is a diagnostic procedure, the most common kinds of pulse oximetry devices used currently are as follows:
Finger Pulse Oximeter – This is the most commonly used device as it’s portable as well as easy to understand and calculate hemoglobin level with this. The working so easy that you can use it on your own without any additional help.
Mostly it comes in a shape of an alligator and can be inserted/clipped to your finger or ear lobe. There is a screen on the clip that reads the oxygen level and differentiates between oxygenated and deoxygenated blood.
One main disadvantage of using this type of Pulse Oximeter is that it may not always provide you with ideal or actual reading in case there are blood clots or if your hand is cold while trying the test.
Handheld Oximeter – This type of Oximeter is mostly used by medical institutes and hospitals to read vital signs of a human being. This is slightly better and sophisticated design of reading and does not have reading screen attached to the machine.
