title: Comparison of two automated sphygmomanometers for use in the office setting.
abstract: OBJECTIVE
  To compare readings obtained using two automated blood pressure (BP) recording devices, BpTRU and Omron 907, in a clinical setting.
  
  
  METHODS
  Two series of 50 patients attending a hypertension unit for 24-h ambulatory BP monitoring had BP recorded either every 1 or every 2 min using BpTRU and Omron 907 devices with the order of the measurements being randomized.
  
  
  RESULTS
  No significant differences for systolic BP between the mean readings taken using the BpTRU or Omron 907 recorders at either 1 or 2 min were observed. Diastolic BP readings were similar using the 1-min interval setting but were 5.0 mmHg lower for the Omron 907 (P<0.001) when readings were taken at 2-min intervals.
  
  
  CONCLUSIONS
  BP measurements can be made in the clinical setting using either the BpTRU or Omron 907 automated sphygmomanometers.
