Accuracy of the OMRON M4 automatic sphygmomanometer

Clarke, Andrew AJ, Gosling, Cameron and Cameron, Melanie (2004) Accuracy of the OMRON M4 automatic sphygmomanometer. Coursework Master thesis, Victoria University.


The Omron M4 (AS) is an upper arm automatic sphygmomanometer that has not been conclusively validated in clinical trials. The aim of this research was to determine whether the Omron M4 was accurate enough for clinical use. Sixty-two young, apparently healthy participants were recruited. Participants had their blood pressure (BP) taken once with the AS and once with a mercury sphygmomanometer (MS) in random order. Results were compared against the British Hypertension Society (BHS), and the Association for the Advancement of Medical Instrumentation (AAMI) protocols for evaluation of automatic sphygmomanometers. We concluded that the Omron M4 is questionable rating according to previously stated guidelines. This minor thesis was written by a post-graduate student as part of the requirements of the Master of Health Science (Osteopathy) program.
