We still have an old Life Sciences PVR machine along with a three year old Parks Flo-Lab. Our protocol has always been to start with a wide thigh cuff (17cm) and then when abnormal to switch to double thigh cuffs (12 cm) to further differentiate disease. Now the newer techs are telling me they never use the wide thigh cuff, but instead use one 12 cm extra long cuff in the thigh and then duplex to further differentiate disease. We never seemed to have a problem with the old Life Sciences or with our protocol. I was told no one ever uses the wide thigh cuff. Should I change the protocol? Do you duplex all your abnormals or do you have a cutoff. Don't you need an additional Dr.'s order for a duplex if they have ordered only a PVR??
