• automated blood pressure monitors;
  • sphygmomanometer

The application of automated devices in measuring patients' blood pressure has been widely adopted in nursing practice. This study compared blood pressure recordings of two automated blood pressure monitors which were commonly used in clinical settings in Hong Kong. Single-arm recordings were obtained from 31 subjects with both devices. Ten blood pressure recordings were obtained for each subject, with half of the subjects taking five measurements from one device first and five measurements from the other device second, and vice versa. A total of 155 sets of measurements were available for analysis. The results indicated that there was no significant difference in the variation of systolic, diastolic, mean arterial pressure and heart rate between these two devices. Implications for future research and development of an improved automated blood pressure device are made.
