Answer

Answer

Standard pulse oximeter probes may be placed on fingers or earlobes of ambulatory patients. Some oximeters use reflectance probes that can be placed on the forehead. Fingernail polish should be removed and peripheral circulation should be maximized by warming or by applying vasodilating cream, if necessary.
