A Pulse Oximeter is a handy tool to have. Besides giving a responder an idea of the patients pulse (which should also be verified manually by palpation) the Pulse Oximeter will also give you an idea of the Patients oxygen saturation (aka SpO2) in their blood.
Normal ranges for SpO2 are 94-99%. 100% can indicate Carbon Monoxide Poisoning. Supplemental oxygen should be considered for patients whose SpO2 is below 90%.
Pulse Oximeters can be ordered fro online outlets for less then 20$ and prove to be a useful tool for evaluating patients
