In this study, the investigators are testing the accuracy of a wrist-worn measurement device by comparing its blood pressure measurement to arterial line (A-line) blood pressure monitors. ...
The JADE wRAP™, a wrist worn cuff to measure blood pressure and its supporting software platform is currently at the final alpha prototype stage of development and is not intended for sa...
A wristband device intended for use as a standalone device, designed for the measurement of intermittent blood pressure, as well as other physiological signals. The device is intended to b...
The aim of the present study is to evaluate the accuracy of measuring beat-by-beat diastolic blood pressure from a non-invasive, cuffless and non-obtrusive watch-like optical device worn a...
We are developing Blood Pressure Imager (BPI), which is a new technology that does not require cuffs or expensive equipment, and can be used by untrained individuals in underserved, low-re...
If blood pressure (BP) measurement is important to monitor blood hypertension and other cardiac diseases, and can be taken using a wrist device, learned societies recommend to take it in specific cond...
Blood pressure measurement in severe obesity may be technically challenging as the cuff of the device may not fit adequately around the upper arm. The aim of the study was to assess the agreement betw...
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...
<b>Objective:</b> Evaluate a method for the estimation of the nocturnal systolic blood pressure (SBP) dip from 24-hour blood pressure (BP) trends using a wrist-worn photoplethysmography (P...
This study proposes an algorithm for the detection of atrial fibrillation (AF), designed to operate on extended photoplethysmographic (PPG) signals recorded using a wrist-worn device of own design. ...
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)
