What is arterial oxygensaturation?
In the blood, red blood cells sit that vouch for the transport of oxigen to the organs. Within in this red blood cells sit hemoglobine (Hb) that at the oxigen binds in the lungs and in the organs the oxigen release. The arterial oxygensaturation, is a degree meter for the quantity oxigen that at the hemoglobine in the red blood cells in the arteriën or blow veins bound is. The saturatie is expressed as a percentage and is with healthy persons more than> 95%. The arteriël oxygensaturation is expressed also as a SPO2.
How can we measure arterial oxygensaturation?]
The measuring of the arteriel oxygensaturation on 2 manners:
1) arterial bloodgas analyse: this method an arterial blood, purchase requires and is free expensive
2) the transcutane measurement with a pulse oxi meter: this method is quite simple and less
duration.
It being this saturation devices / pulse-oximeters that www.saturatiemeter.eu sells on this website.
How does a saturation device / pulsoximeter work?
When the hemoglobine bound is at oxigen molecules has one redder color then hemoglobine that no oxigen holds. This differ is observed in color by the pulsoximeter. This to measure steers the saturatiemeter infrared light wave through the skin and catches he the rebounded lift back on. From the difference in color between dispatched and rebounded light can one the saturation - the content at hemoglobine that at oxigen bound is - fixed.
What is desaturation?
One speaks is of desaturation as the arterial oxygensaturation is less then <90%. Desaturation want to say that the patient insufficient oxigen inhales whether the oxigen exchange between the lungs and the blood not works properly.
Causes of desaturation
Desaturation can causes become through respirations illnesses, as asthma and COPD. By heart problems, vague vochtophopingen in the lungs act, through which the oxigen exchanges take place can less good, and with desaturatie till consequence. (= Left decompensatie - overvulling) A vague occurring form of desaturatie is the nocturne desaturatie. This is a consequence of the disorder sleep-apneu, stop breathe by which men during the night different times with during tens seconds till even single minutes.
