Implantable accelerometer for determination of blood pressure
2013 Transducers & Eurosensors XXVII: The 17th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS & EUROSENSORS XXVII), 2013We present a new method to continuously monitor blood pressure using an acceleration sensor which is implanted on an artery using minimally invasive techniques, and which does not limit the mobility of a patient in everyday life. It is demonstrated by in vivo experiments that the reflected wave transit time (RWTT) can be reliably determined from ...

Implantable acceleration plethysmography for blood pressure determination
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013This paper presents an implantable accelerometer which detects plethysmograms directly at an artery. The sensor provides a new method for continuous blood pressure monitoring. In vivo measurements indicate that the accelerometer is well suited for determining the Pulse Transit Time (PTT) and the Reflected Wave Transit Time (RWTT).

The Tecumseh Blood Pressure Study
Archives of Internal Medicine, 1990In Tecumseh, Mich, we obtained blood pressure (BP) self-determination data in 608 healthy adults (327 men, 281 women; average age, 32.6 +/- 3.5 years) representing a wide range of educational backgrounds. The average (+/- SD) home BP (average 12.7 readings over 1 week) was 120.7/74.8 +/- 10.4/8.6 mm Hg for men and 110.9/69.9 +/- 10.1/7.7 for women. One

Noninvasive determination of arterial elasticity and blood pressure. Part II
Blood Pressure Monitoring, 2013The oscillometric method is used in the medical practice for measurement of arterial blood pressure and, rarely, for estimation of arterial elasticity. In the previous paper of this series, the relations between arterial volume pulsations and volume-to-pressure curve (elastogram) were examined resolving the problem for evaluation of arterial volume ...

Prevalence and determinants of blood pressure screening in Pakistan
Journal of Hypertension, 2005We analysed data collected during a nationwide cross-sectional household survey to estimate the prevalence of, and to identify factors associated with, blood pressure screening in Pakistan.A population-based cross-sectional survey (National Health Survey of Pakistan 1990-1994).During 1990-1994, 18 135 people aged at least 6 months were surveyed across ...

Determinants and Consequences of the Diurnal Rhythm of Blood Pressure
American Journal of Hypertension, 1993The diurnal rhythm of blood pressure (BP) is influenced by both extrinsic and intrinsic factors, with the former usually being of greater significance. Non-dippers, in whom the normal nocturnal fall of pressure is diminished, have been reported to show more target organ damage (left ventricular hypertrophy (LVH)) than dippers, which may be explained by

Determinants of Rise in Blood Pressure in Normotensive Children
Journal of Hypertension, 1987Thirty-nine initially normotensive children (25 girls) with a large increase in systolic blood pressure (SBP) over a period of 7 years were compared with 78 children with a small increase, matched for age and gender. They were selected from a random sample of 596 Dutch children who were examined at an initial examination and 4 weeks later, and at ...

The Accuracy of Indirect Determination of Blood Pressure in Dogs
Research in Veterinary Science, 1973Summary A comparison has been made between direct and indirect measurements of systolic pressure in 50 dogs. Direct pressure was measured with a strain gauge transducer; indirect pressure was measured with an infant sphygmomanometer incorporating a xylol pulse indicator.
