The pulse oximeter is a valuable tool in the prehospital setting and is a important part of the vitals signs and overall patient assessment. These $600 machines measure the oxygen saturation levels in the circulating hemoglobin and will detect the pulse wave. A normal saturation level for a non smoking adult is around 95-100% on room air.
Now tell me why this Baby Annie doll apparently has a Sp02 of 65% and a pulse rate of 80bpm.
Now I understand people calling it a random number generator…
Remember folks, treat the patient, not the machine!
