This paper, which summarizes the conclusions of a WHO Expert meeting, is aimed at proposing indications to develop technical specifications for an accurate and affordable blood pressure measuring device for office/ clinic use in low resource settings. Blood pressure measuring devices to be used in low resource settings should be accurate,...

Objective: To evaluate three methods aimed at the reconstruction of brachial pressure from non-invasive finger arterial pressure measurements as implemented in the Finometer™, (FMS, Finapres Measurement Systems, Arnhem, Netherlands), the successor to the Finapres™ (TNO Siomedical Instrumentation, Amsterdam, Netherlands). Methods: Finger arterial...

Background: Continuous beat-to-beat noninvasive blood pressure (BP) measurement is possible with Portapres®. It constructs finger arterial waveforms beat-to-beat. Dedicated software is used to analyze the arterial waveforms. A new technique has been developed to reconstruct brachial intraarterial pressure that uses return to flow (RTF). This...

Oscillometric blood pressure devices tend to overestimate systolic blood pressure and underestimate diastolic blood pressure compared with sphygmomanometers. Recent studies indicate that discrepancies in performance between these devices may differ between healthy and diabetic subjects. Arterial stiffness in diabetics could be the underlying...

The relationship between aortic flow and pressure is described by a three-element model of the arterial input impedance, including continuous correction for variations in the diameter and the compliance of the aorta (Modelflow). We computed the aortic flow from arterial pressure by this model, and evaluated whether, under orthostatic stress,...

Objective. Arterial pressure waveforms distort between brachial and finger arteries, causing differences mainly in systolic pressure. Distortion, reportedly, can be removed by applying a waveform filter to the finger pressure. Design. We analysed the data from two studies that detected discrepancies in systolic tracking between Finapres and...

1. The aims of this study were to determine the clinical feasibility of continuous, non-invasive Finapres recordings as a replacement for intrabrachial pressure during a 30 min head-up tilt, and the reliability of continuous cardiac output computation by pulse contour analysis from the finger arterial versus the brachial waveform. 2. In eight...

Om een indruk te krijgen van de wijze van bloeddrukmeting en de criteria voor het stellen van de diagnose hypertensie in de praktijk van de jeugdgezondheidszorg werd in 1989 een schriftelijke enquête gehouden onder een aselecte steekproef van 100 schoolartsen. De respons bedroeg 62. De resultaten lieten grote verschillen in zowel methoden van...

The clinical utility for autonomic research purposes of the Finapres<sup>TM</sup>, a device for measuring finger arterial pressure continuously and noninvasively, was assessed by estimating its accuracy, precision and within-subject variability in 48 subjects, aged 18-65 years, in comparison with intraarterial brachial blood pressure. At...

Pressure-volume (p-V) relationships of a segment of the forearm circulation have been measured in nine male healthy subjects. Forearm volume was measured using electrical impedance plethysmography, arterial transmural pressure by subtracting mean arterial pressure measured contralaterally in a finger from the pressure in a cuff placed over the...
