Lyrics
Why does that little finger clip glow red?
Let's find out!
Put your index finger in the little plastic clip
Going on a light beam scientific trip
Look inside the sensor, see that ruby light
Shining through your fingernails, super duper bright
There are two different lights dancing through your skin
One is cherry red and one is hit within
Infrared is invisible to human eyes
Working as a team to take home the prize
Red light, 660 nanometers
Infrared, 940 nanometers Passing through your blood cells,
checking on the scene
Drawing little pulses on the monitor screen
Red light on your finger, telling you the score
Measuring the oxygen from 95 to 4 98%,
99
Showing where the fresh air through the body went
Hemoglobin holding oxygen so tight
Absorbing all the colors of the dancing light
Biomed sensor, shiny and sweet
Count your pulse along with the beat
Every time your heart beats, blood rushes in
More light is absorbed underneath the skin
The photo deal catches what comes out the other other side
Doing super fast math on a photon ride
We test the finger clip on an artificial thumb
Making sure the accurate results always come
Red light on your finger telling you the score
Measuring the oxygen from 95 to 4 98%,
99
Showing where the fresh air through the body went
Helioglobin holding oxygen so tight
Absorbing all the colors of the dancing light
Biomed sensors, shiny and sweet
Count your pulse along with the beat
Take a deep breath
Fill up your lungs
Exhale Send that oxygen through every vein
Now watch that number light up again
100
Yeah!
Red light on your finger, telling you the score
Measuring the oxygen from 95 to 4 98%,
99
Showing where the fresh air through the body went
Hemoglobin holding oxygen so tight
Absorbing all the colors of the dancing light
Biomed sensors, shiny and sweet
Count your pulse along with the beat
Pipip 99
Full of oxygen
Full of energy
