Fingertip Pulse Oximeter is a clamp-like device used for measuring the oxygen saturation level throughout the body. It can detect even the iota of changes regarding the oxygen flow in every nook and cranny of our internal body parts.
The heart pumps oxygen in our body, which defines our overall body functionalities and healthiness, making it crucial to frequently check the blood oxygen level.
While performing a pulse oximetry reading, a clip-like device is placed on our finger, toe, or earlobe. Subsequently, small beams of light pass through the blood and measure the amount of oxygen in the blood. As per health specialists, 89% of blood carries oxygen in our body, which keeps our cells and body healthy.
The probe is supposed to be well-positioned on the finger to ensure the Fingertip Pulse Oximeter functions correctly, and you get accurate results ultimately.
A teeny-tiny fingertip device can provide you some valuable information about your health. Ain't that amazing. Yes, big time!
Fingerology
It may pop up in the back of your mind, whether for how long the clip should be kept on the finger and which finger gives the best results?
You may have overheard health specialists talking about placing the Fingertip Pulse Oximeter on the index finger. It has long been an axiom for health technicians to choose the index finger over the rest.
However, a recent study shows something contradictory to the long-standing index finger rule. The most accurate and highest reading came from the dominant hand's middle finger, followed by the thumb finger as per study findings.
For instance, if you are right-handed, you may use your right hand's middle finger for pulse oximetry. Left-handed people can use the middle finger of their left hand.
However, using the index finger is still acceptable since the difference is relatively minimal. Irrespective of the finger, misuse of Fingertip Pulse Oximeter can give birth to tissue injury.
As far as the time duration is concerned, some oximeters can provide the reading within 3 seconds. Most of the oximeters take an average of 8 to 15 seconds to measure the blood's oxygen level.
Factors Causing Inaccurate Reading
Various factors that are likely to cause an inaccurate reading comprises;
- Nail polish or pigment on the finger can interfere with oximetry measurement; hence it is recommended to remove the nail polish prior to performing the reading
- Bright light, be it sunlight or the operating light, both are supposed to interfere with the light detector and give a false reading
- Poor perfusion, a decreased arterial blood flow to the extremities is one of the primary reasons for erroneous oximetry measurement
- Patient movement is another factor that can translate into wrong readings
- If one is exposed to fire or smoke, it increases the probability of false reading since Fingertip Pulse Oximeter cannot detect the intermingling of Hb and CO, results will show an increased amount of SpO2
Key Take-Aways
Pulse oximetry is a non-invasive, quick, and completely painless test for monitoring SpO2 intermittently and continuously. Everyone is recommended to regularly check their blood oxygen level and consult with a doctor when find the readings go above or below certain levels.
Take good care of yourself and show some respect to your oximeter by cleaning it gently with a damp cloth or alcohol swab.
