Pulse Oximetry Measurements to Monitor Oxygen Adequacy
Installation of Pulse Oximetry to Monitor Oxygen Adequacy
pulse oximetry measurements is used to monitor the amount of oxygen in patients. Pulse oximetry is performed in patients who experience respiratory disorders, fluctuating levels of consciousness, serious illness, and patients who have abnormal vital signs.
However, in patients with hypothermia, vasoconstriction, anemia, hypotension, or patients who have artificial or painted nails, the results of pulse oximetry monitoring may be impaired or become inaccurate.
Pulse oximetry can be placed on the fingers or toes, the auricle, the edge of the nose or by closing and uniting all the baby’s toes using pulse oximetry
There is one thing that must be considered when the pulse oximetry is installed, it can only detect the percentage of red blood cells without distinguishing other components or substances that enter the red blood cells. For example: in patients who experience carbon monoxide gas poisoning, the pulse oximetry measurement results will appear normal.
When this happens, then the patient must be examined for arterial blood gas samples (blood gas analysis) to determine the oxygen content in the arteries. Then the results of arterial blood gas examination are compared with the results of pulse oximetry measurements. If there is a difference then check the carbon monoxide level and do not use oximetry until the carbon monoxide level drops to near normal values.
