BACKGROUND Nowadays, an increasing number of dialysis machines lodge a blood pressure (BP) measuring device, whose accuracy has a clear implication for the patients' clinical management. METHODS An automated oscillometric sphygmomanometer (HD-BPM by Gambro Dasco) used during haemodialysis was submitted to both in vitro and in vivo tests, in order to evaluate some modifications aimed at improv...

The aim of this study was to evaluate the correspondence of blood pressure (BP) measured using the direct intra-arterial method and indirect oscillometric monitor method. Twenty-three newborns with radial arterial catheters inserted were enrolled in this study. The gestational age (GA) ranged from 25-40 weeks and birth weight (BW) ranged from 700-3,550 g. Direct BP was measured using radial art...

Oscillometric Blood Pressure (BP) monitors are omnipresent and used on a daily basis for personalized healthcare. Nevertheless, physicians generally approach these devices cautiously since the mercury Korotko sphygmomanometer remains the golden standard. Various reasons explain the hesitating attitude of the medical world towards automated BP monitors: (i) its principle is based on the pressure...

Measurement of the arterial blood pressure (BP) is a time-honored, vital piece of medical information whose accuracy is seldom questioned. This review identifies the unappreciated weakness of the early validation data that compared the cuff to intra-arterial BP's. Unfortunately, the inaccuracy of the auscultatory systolic (SBP) and diastolic (DBP) measurements are necessarily transmitted to the...

Blood pressure is an important vital sign that sometimes requires continuous measurement. The current methods include cuff measurements (manual auscultation and oscillometric techniques) for non-continuous measurement invasive arterial cannulation use of photoplethysmography as a cuffless, non-invasive, blood system investigated through the four neural networks. These predict systolic pressure,...

Although there are several indirect or noninvasive methods (i.e., oscillometric and Doppler) available, it is sometimes impossible to obtain a reading on exotic patients. The Doppler method is more versatile than the oscillometric method, and is the method used by the author for all exotic patients. The ultrasonic Doppler flow detector (Parks Medical Electronics Inc., Aloha, OR) uses ultrasonic...

The Vasotrac monitor provides non-invasive near-continuous blood pressure monitoring and is designed to be an alternative to direct intra-arterial blood pressure (BP) measurement. As compared to radial artery invasive BP and upper arm non-invasive BP, Vasotrac readings have been found to have a good agreement with them. However, discrepancies have been reported when rapid changes in BP exist. I...

In occidental countries, peripheral arterial disease (PAD) is an important health issue; however, most subjects are asymptomatic (~50%) and therefore undiagnosed and untreated. Current guidelines recommend screening for PAD in primary care setting using ankle brachial index (ABI) in all patients with cardiovascular risks. This is, however, not performed strictly because the standard Doppler met...
