Pulse Oximeter

The human body in full fitness, sound health and a myriad of activities is a beauty and a wonder to behold. Think of the sporting activities and other endeavors that require physical activity for them to be accomplished and you can’t help but wonder at what the body can do.
Sadly, not everyone can be said to be in good physical and health condition. Fact is that a lot of people are very limited in what they can engage in because of one condition or the other, or even as in some cases, a combination of health issues.
However, if the body condition can be monitored, it can help manage or even treat the ailment. One such instrument for monitoring the body’s system is the pulse oximeters.
What Are They? 
They are instruments used to monitor the rate of the oxygen content in the body system, also known as oxygenation or oxygen saturation. It is a noninvasive procedure (this means that it is a procedure that doesn’t involve breaking through your skin) that is totally safe and is solely for the good of the patient.
It should be understood though that pulse oximetry is primarily the work of health care professionals, and is further explained here. The oximeter is merely the tool used for testing.
The procedure can simply be described thus: the clip like-part of the device is placed on either the ear lobe or fingertip. This device, known as a probe, measures the oxygen level in the blood using light and can at the moment, depending on the emergency, be used to determine if an individual needs extra oxygen.
Through this procedure, health care providers are able to detect health conditions that are usually the cause of respiratory dysfunction. One of such health challenge or condition is Hypoxemia which in most cases is the root cause of respiratory dysfunction or deterioration.
Why And When Is It Necessary?
Pulse oximeters have time and time again proven to be life savers because, the primary information it offers would normally determine how best to approach a health crisis. Below are some examples of the uses it can be put to:
  1. It is used to assess whether an individual needs help breathing.
  2. It is used when procedures that will require that the patient be sedated e.g. surgeries, are to be performed. It is usually done during or after the procedure has been performed.
  3. Sometimes, there are crucial moments when an oxygen ventilator is given to a person. In such situations, there may arise the need to use it to measure how effective the ventilator that has been given to the individual is.
  4. It is also used to ascertain whether an individual will be able to cope with increased physical activity.
  5. It can also be used to evaluate how effective a new medication has been in the treatment of lung problems in an individual.
  6. Generally, people with cardiovascular conditions or respiratory problems will require it.
  7. It is put on infants, especially those in the intensive care unit to keep watch on their oxygen saturation and also to alert staff if the oxygen saturation works. 
This list is not necessarily exhaustive of the uses of the device, you can go to https://www.medicalnewstoday.com/articles/318489.php#What-to-expect-from-pulse-oximetry to get more clarity. There might be many other scenarios that may ordinarily not be envisaged until the occasion calls for its use.
Does It Have Any Side Effects?

From the study so far, there are no side effects arising from its use. It is therefore perfectly safe. The only potential risk during its use is the danger of a false reading. This can occur when it is not properly fitted on the person to be checked or when there is an abrupt change in the positioning of the wearer e.g. when they roll over while asleep.

These however are not frequent occurrences, and therefore no reason to panic. It just means that care should be taken during its use.

Other Things To Note

Generally, it is simply wise that for anyone using or about to get one should properly discuss with and get a doctor’s advice. They should also keep record of its readings over time and constantly report same to the doctor.

They should also be able to read about pulse oximeters for themselves so as to know what it is they are about to get for themselves. Furthermore, it should also only be purchased from properly licensed and recommended manufacturers or health stores.


Certain health challenges require constant monitoring and evaluation. This is to ensure that any emergencies which might, if left unchecked, result in serious health complications are spotted and handled before they get out of hand.

Therefore, if you have certain respiratory challenges, dizziness or difficulty breathing, endeavor to get good medical help and if you can, get a pulse oximeter.
