Comparability of oscillometric to simultaneous auscultatory blood pressure measurement in children.

Uncertainty exists regarding the accuracy of automated blood pressure (BP) measurement in children. We recorded oscillometric waveforms in children, derived oscillometric BPs using two standard algori...

Real-Time Blood Pressure Estimation from Force-Measured Ultrasound.

Our objective is to create a blood pressure measurement device which may provide a way to easily acquire frequent measurements. Common techniques to measure blood pressure include an arterial catheter...

Continuous Non-Invasive Blood Pressure Measurement Using Pulse Transit Time in Children and Adolescents.

As an alternative to ambulatory 24-h blood pressure monitors, the continuous, non-invasive blood pressure recording using pulse transit time (PTT) was compared with both oscillometric and intra-arteri...

Accuracy of oscillometric blood pressure algorithms in healthy adults and in adults with cardiovascular risk factors.

Fixed-ratio and slope-based algorithms are used to derive oscillometric blood pressure (BP). However, a paucity of published data exists assessing the accuracy of these methods. Our objective was to d...

Screening for hypertension: an elevated office blood pressure measurement is valuable, adding an automated one is even better.

Previous studies have examined the relevance of hypertension (HTN) screening in walk-in clinics. So far, no valid algorithm has been proposed on how to integrate HTN screening in this context. The aim...

Clinical Trials [10607 Associated Clinical Trials listed on BioPortfolio]

Zero to Five Automated Oscillometric Office Blood Pressure (AOBP) Measurement

The Hypertension Canada Clinical Practice Guidelines for blood pressure measurement using AOBP recommend against any wait time prior to commencing the measurement. The recent AHA guideline...

Accuracy of Non-invasive Non-oscillometric Blood Pressure Wristband

The primary objective of the present investigation is to determine the accuracy of a non-invasive non-oscillometric blood pressure wristband device when compared to invasive intra-arterial...

Comparison of the Ankle-Brachial Index Measurement Using a Specific Oscillometric Device vs. the Doppler Method

Several methods are available to measure ankle brachial index (ABI) non-invasively. A recent scientific statement of the AHA considers the Doppler method as the reference. However because ...

Invasive Validation of Non-invasive Central Blood Pressure Measurements Using Oscillometric Pulse Wave Analysis

There is growing evidence that central blood pressure is a better predictor of hypertensive end-organ damage and cardiovascular outcome than routine brachial readings. We aimed to evaluat...

Non-invasive Validation of Non-invasive Central Blood Pressure Measurements Using Oscillometric Pulse Wave Analysis

There is growing evidence that central blood pressure is a better predictor of hypertensive end-organ damage and cardiovascular outcome than routine brachial readings. The investigators a...

Medical and Biotech [MESH] Definitions

The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine.

Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.

Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

A response by the BARORECEPTORS to increased BLOOD PRESSURE. Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.

Measurement of the blood pressure of the retinal vessels. It is used also for the determination of the near point of convergence (CONVERGENCE, OCULAR). (From Cline, et al., Dictionary of Visual Science, 4th ed)
