Blood Pressure Cuffs

We are currently using the Omicron automatic blood pressure cuffs. It a nice device, but I think that the readings are only accurate half of the time. I think the problems occurs with the cuff not being a soft cuff and the way it fits around the arm. In two occassions, I had to take my patient to oral surgery to get their blood pressure read. If the cuff was more accurate we would be able to save alot of time, and perhaps finish the appointment. I guess we are in the phase of trial and error. Hopefully we can purchase new soft cuffs for our machines.
