Alternatives to the mercury sphygmomanometer.
The mercury sphygmomanometer was introduced over 100 years ago. Mercury, however, is a potent human neurotoxin. An international effort has developed to eliminate health-care sources of mercury--the thermometer and sphygmomanometer--and replace them with less toxic alternatives. There is concern regarding the accuracy of these alternative devices. We conducted a literature review of articles pu...
متن کاملExperience with the random-zero sphygmomanometer.
SOURCES of variation and bias in the measurement of blood pressure with a sphygmomanometer have been identified in the observer, the subject, and the instrument (Rose, Holland, Crowley, 1964). Systematic and non-systematic variation in measurement, which clinicians may be content to ignore, can attain importance in research by vitiating between-group comparisons through variable bias or necessi...
متن کاملClinical experience with use of ultrasound sphygmomanometer.
The performance of an ultrasound sphygmomanometer (Arteriosonde 1217) has been compared with that of the London School of Hygiene and Tropical Medicine and Hawksley sphygmomanometers. The Arteriosonde gave closely similar values of systolic blood pressure of the other instruments but diastolic blood pressure lay midway between phase 4 and phase 5 of the Korotkoff sounds. Observers using the Art...
متن کاملPotential problems with the random-zero sphygmomanometer.
The random-zero sphygmomanometer is frequently used in epidemiologic and clinical research to increase the reliability and validity of blood pressure readings. However, recent reports have suggested that there is a correlation between the zero values of a random-zero sphygmomanometer and the zero-corrected blood pressure readings obtained. The design of the random-zero sphygmomanometer would su...
متن کاملProperties of the random zero sphygmomanometer.
The random zero sphygmomanometer is widely used in studies involving blood pressure measurement because it is believed to eliminate digit preference and reduce measurement error. We performed blood pressure measurements sequentially using random zero and standard sphygmomanometers in random order in 1,356 participants in the Cardiovascular Health Study. Despite adherence to the manufacturer's i...
