Pulse Oximeter a life saver?

What is a Pulse Oximeter? A Pulse Oximeter is a healthcare device used to measure the oxygen level (oxygen saturation) of the blood. It is an easy, painless, and accurate measure of how much oxygen is being sent to the parts of our body furthest from our heart, such as arm to leg.

Why Pulse Oximeter? Simple! To find the oxygen saturation in our blood. This information is needed in situations like the following.

  • During or after surgery, treatments that use sedation.

  • To analyze how well our lung is functioning during the medication.

  • To check whether the person needs an external oxygen supply (ventilator).

  • To check if the person stops breathing during sleep (sleep apnea).

Pulse Oximeter can also be used to check health conditions that affect the blood oxygen level

  • Heart attack

  • Heart failure

  • Chronic obstructive pulmonary disease (COPD).

  • Anemia

  • Lung Cancer.

  • Asthma

  • Pneumonia

How to use Pulse Oximeter? Very simple steps to follow:

  • A clip-like device called a probe will be placed on our finger or earlobe. In hospitals, a probe with sticky adhesive may be placed on our forehead or finger.

  • The device shows measured values (readings)

Safe Values Normal Pulse Oximeter readings usually range between 95 to 100 percent. Readings under 90 percent are considered low and will require immediate medical attention.
