Fingertip Pulse Oximetry: Reasons To Use


Our whole body system requires oxygen to function and, in fact, to stay alive. Cells start to malfunction and ultimately die without oxygen. The cell death can lead to critical medical symptoms, like chest pain, shortness of breath, increased heart rate, etc. as a result, the organ fails. So, to prevent yourself from such severe medical conditions, you need to keep a check on how much oxygen is there in the blood. Hence, here you need to invest in pulse oximetry to regulate the percentage of oxygen in the body. 

How Does Fingertip Pulse Oximetry Work?

Pulse oximetry will regulate the level of oxygen in hemoglobin proteins. It is a painless and noninvasive test that measures the level of oxygen saturation in your blood. This process in the body is called Blood Oxygen Saturation (SpO2).

Within a matter of seconds, the device provides precise details on your SpO2 level as well as pulse rate. The device can identify even small variations in oxygen instantly, i.e., how it pumps oxygen from the heart to the legs, arms, or any other part of the body. In case of abnormal readings, you can immediately take action for the same.

The detector is first placed on a finger, toe, or earlobe. You may just feel a slight pressure where you put the pulse oximetry. It then operates by flashing light into a nearly transparent portion of your skin. The light radiates through pulse oximetry placed on the other surface of your skin.

In simple terms, one side of the detector throws the light while the other gives the reading. When the examination completes, remove the device.

Causes Of Blood Oxygen Saturation

SpO2 can drop due to several reasons, such as

  • sleep apnea
  • suffocation 
  • choking
  • pneumonia
  • emphysema
  • lung infections
  • inhaling poisonous chemicals
  • heart failure
  • a history of heart attacks
  • general anesthesia
  • drowning
  • allergic reactions
  • lung cancer

Advantages Of Using The Fingertip Pulse Oximetry

If a person has sleep apnea or severe snoring, he or she can use the pulse oximeter to control the nighttime oxygen saturation level.

Use personal device while exercising to evaluate the safety of people with cardiovascular problems.

Doctors use it to check the effect of lung medications on the patients.

Some physicians utilize the device for the stress test as well.

People who have asthma can use the device to evaluate the severity of exacerbations and attacks both.

Doctors can assess the effectiveness of a ventilator with the help of this device.

Oxygen levels monitoring during or after surgical procedures is possible with it

During physical activities, patients can regulate their oxygen flow with an in-home pulse oximeter.


Pulse oximeters have no side effects or risks associated with it. You may just feel a little skin irritation due to the adhesive on certain kinds of probes. Thus, individuals with unfavorable breathing and heart conditions should make sure to buy this device. It enables them to always keep their health on a check from the comfort of their home. No doubt, a pulse oximeter is a totally safe and reliable device.
