OBJECTIVE To evaluate the agreement of blood pressure measurements and hypertension scores obtained by use of 3 indirect arterial blood pressure measurement devices in hospitalized dogs. Design-Diagnostic test evaluation. ANIMALS 29 client-owned dogs. PROCEDURES 5 to 7 consecutive blood pressure readings were obtained from each dog on each of 3 occasions with a Doppler ultrasonic flow detec...

In the most common version of an oscillometric blood pressure monitor, the output from the pressure transducer, Y(t), is split into two parts, and used for separate determinations of the pressure inside the pneumatic cuff and its fluctuating part; the latter is derived by sending Y(t) to a high-pass filter (HPF) and amplifying the filtered part to obtain the oscillometric signal O(t). Using a t...

In this paper oscillometric method is used to develop an adaptive non-invasive blood pressure measurement system. To overcome the drawback of conventional oscillometric method an algorithm is developed. During the time of deflation and inflation process the step size of pressure pumped and released using pump and valve respectively is varied adaptively by continuously monitoring the feedback wh...

Relatively little is known on how the Doppler method compares with oscillometric measurement using a conventional automatic blood pressure device to determine the ankle-brachial index, when determinations are performed by physicians with little experience. To assess the diagnostic efficacy of both methods in this professional group, we calculated their sensitivity, specificity, and positive and...

OBJECTIVE To define the range and variability of ambulatory blood pressure in normal schoolchildren. DESIGN Prospective study. METHODS Resting blood pressure of 1121 schoolchildren from Newcastle upon Tyne was recorded. An ambulatory blood pressure device, which uses both auscultatory (Korotkoff) and oscillometric methods of blood pressure measurement, was then put in place for 24 hours. ...

OBJECTIVE To compare blood pressure readings obtained with two commonly used oscillometric monitors: Omron HEM 711 AC (OM) and Welch-Allyn 52000 series NIBP/oximeter (WA) with mercury sphygmomanometers (Merc) in subjects with atrial fibrillation. METHODS We recruited 51 hemodynamically stable subjects with atrial fibrillation. Fifty four subjects in normal sinus rhythm served as controls. Sup...
