Before recommending that this technique be used in research, several points deserve emphasis. First, the accepted standard device used3 for noninvasive BP measurement is the mercury sphygmomanometer. An AUD may be a convenient surrogate for self-measurement of BP for patients who have difficulty in achieving skill and accuracy with a mercury sphygmomanometer. Second, when choosing an AUD for clinical use or for research, preference should be given to devices that have been authorized by a regular validation procedure.4- 5 However, the accepted validation protocols are time consuming and expensive because a large number of subjects are tested across a wide range of BPs, which requires the employment of many well-trained observers.4- 5 At present, manufacturers have no obligation to have AUDs validated independently, even though there has been a call for such action.4 Third, the AUD needs to be periodically recalibrated during the course of prolonged studies.
