How Does the Activ8rlives Pulse Oximeter2 Work?
The Activ8rlives Pulse Oximeter2 is a non-invasive wireless method allowing the monitoring of
the saturation of haemoglobin in your blood.
A sensor is placed on a thin part of your body, usually a fingertip or earlobe (separate adapter
required).
Light of two wavelengths is passed through the finger (or earlobe) to a photodetector. The
changing absorbance at each of the two wavelengths (red 660nm and infrared 905nm) is
measured, allowing determination of the absorbances due to the pulsing arterial blood alone
(the blood flowing from the heart and lungs), and excludes venous blood (the blood returning
to the heart and lungs), skin, bone, muscle, fat, and finger nails.
A blood-oxygen monitor displays the percentage of arterial haemaglobin (Hb) in the
oxyhaemoglobin (HbO
2
) configuration. Acceptable normal ranges for patients without COPD
with a hypoxic drive problem are from 95-99 percent (%), in those with a hypoxic drive problem
would expect values between 88-94%. Values of 100% can indicate carbon monoxide
poisoning. For a patient breathing room air at sea level, an estimate of arterial oxygen
saturation levels (pO
2
) can be made from the blood-oxygen monitor SpO
2
reading.
The monitored signal fluctuates in time with the heart beat because the arterial blood vessels
expand and contract with each heart beat. By examining only the varying part of the
absorption spectrum (essentially subtracting minimum absorption from peak absorption), a
monitor can ignore other tissues or nail polish (though black nail polish tends to distort readings)
and discern only the absorption caused by arterial blood. Detecting a pulse is therefore
essential to the operation of the
Activ8rlives Pulse Oximeter2 and it will not function if there isn’t
one.
Your Activ8rlives Pulse Oximeter2 will give you two important pieces of information: your
oxygen saturation levels (SpO
2
) and your pulse rate in beats per minute (bpm).
If in doubt about your health, please consult your medical team first and follow their advice
closely.
