Choosing Best Pulse Oximeter for Asthma: Why It Is Important?

The blood oxygen level in the body (or oxygen saturation levels) measures how much oxygen is present in the red blood cells.

Studies show that maintaining a precise balance of oxygen-saturated blood is crucial for good health.

And this process of balancing is automated by your body in most 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 of oxygen saturation in such conditions need to be monitored regularly for avoiding any serious problems.

Hypoxemia (blood oxygen levels below normal) is a condition of concern for most patients.

In case you are suffering from severe lung conditions, you need to know about the normal oxygen levels that are right for you.

Also, you must maintain the same to avoid any severe 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 a pulse oximeter.

In most cases, a Pulse Oximeter is used to measure two different things, namely:

  • Heart rate
  • Oxygen saturation in the blood

With Pulse Oximeter, getting count or details about heart rate is pretty straightforward. It works by picking the lub-dub of the heart and then translating 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 calculate the oxygen level with the help of a sensor attached to the Pulse Oximeter.

How Does It Work?

Pulse Oximeter works using a straightforward principle, wherein it considers the method by which absorption of red and infrared lights occurs.

This absorption is characterized by oxygenated and deoxygenated hemoglobin in the human body.

In the case of oxygenated hemoglobin, it shall absorb infrared and allow red light to pass through. In contrast, in the case of deoxygenated hemoglobin, then you could see absorption of more red light and allow infrared 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:

1- Finger Pulse Oximeter – This is the most commonly used device as it’s portable and easy to understand and calculate hemoglobin levels.

It works so easily that you can use it on your own without any additional help.

Mostly it comes in the 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.

2- Handheld Oximeter – Medical institutes and hospitals mainly use this type of Oximeter to read the vital signs of a human being.

This is a slightly better and more sophisticated reading design and does not have a reading screen attached to the machine.

There is a cable attached that reads the sign and then shows the result on another screen.

A doctor can better understand your body with this machine as it gets more details about your pulse and blood levels.

3- Fetal Pulse – This Oximeter is used for babies to know whether the child is healthy.

However, this kind of practice is not advised on newborn babies as, in such cases, it is not always possible to get accurate readings, and the passage of light could seriously damage them.

How Does Pulse Oximeter for Asthma Help?

The most common misconception that usually gets into patients’ minds is that oxygen saturation shows a dip while you are affected with asthma.

However, the fact is, this is not always the case, and an ideal way to ensure this is by measuring your oxygen saturation levels.

The best possible method to do so is by using a Pulse Oximeter.

As per recent research, it was pointed out that most asthma patients use a pulse Oximeter in their home to get their oxygen saturation levels tested on their own.

This is best done to ensure that they keep a tab on oxygen saturation levels and take appropriate treatment before the situation gets out of control due to acute asthma problems.
