A nonadhesive sensor is best for latex allergy, and the earlobe site is the best choice for this patient with peripheral vascular disease and edema. Select forehead, ear or bridge of nose if an adult patient has a history of peripheral vascular disease. Do not attach probe to finger, ear, forehead, or bridge of nose if area is edematous or skin integrity is compromised. Do not use disposable adhesive probes if the patient has latex allergy. Do not attach probe to fingers that are hypothermic. Do not place the sensor on the same extremity as the electronic blood pressure cuff because blood flow to the finger will be temporarily interrupted when the cuff inflates.
