An evaluation of the Takeda UA751 automatic sphygmomanometer.

The Takeda UA751, a simple automatic blood pressure measuring device, was compared with standard osciltatory measurement. There was little or no systematic difference in pressure determined by the automatic or manual method and the correlation between the two devices for both systolic and distolic pressure was satisfactory. This suggests that the Takeda UA751 is an appropriate device for patient self monitoring of blood pressure or as a measure of pressure in group outcome trials. The results essential replicate an evaluation by Steptoe and Molineux (Behav. Res. Ther. 24 223-226, 1986) of an earlier version of the Takeda (the Copal UA251) that used a different method for determining blood pressure.
