Summary of "Predictive validity of automated oscillometric blood pressure monitors for screening atrial fibrillation: a systematic review and meta-analysis."

This study was conducted to verify if automated oscillometric blood pressure monitors (AOBPMs) have sufficiently high predictive validity to screen patients with atrial fibrillation (AF).

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...

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...

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...

Comparison of routine and automated office blood pressure measurement.

From April to October 2018, we implemented a blood pressure measurement quality improvement project at our Hypertension Center. We aimed to compare blood pressure measured using routine, non-standardi...

Predictive validity of preschool screening tools for language and behavioural difficulties: A PRISMA systematic review.

Preschool screening for developmental difficulties is increasingly becoming part of routine health service provision and yet the scope and validity of tools used within these screening assessments is ...

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...

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...

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...

Blood Pressure Assessment in Atrial Fibrillation

This is a cross-sectional study including patients with permanent atrial fibrillation. Assessment will include: - clinic blood pressure measurements (mercury sphygmomanometer and autom...

Medical and Biotech [MESH] Definitions

In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.

Devices for continuously measuring and displaying the arterial blood pressure.

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.
