BACKGROUND:: The difference between clinic and ambulatory blood pressure (BP) is a poor estimate of the true white-coat effect (WCE) measured with beat-to-beat recording. METHOD:: We investigated whether the difference between clinic and home BP (home WCE) was a better estimate of true WCE than ambulatory WCE. In 73 young ...

It is generally assumed that skin vascular resistance contributes only to a small extent to total peripheral resistance and hence to blood pressure (BP). However, little is known about the impact of skin blood flow (SBF) changes on the diurnal variations of BP under ambulatory conditions. The main aim of ...

Intra-vesical pressure measurement as the reference standard for assessing intra-abdominal pressures is mainly indirect and discontinuous. We therefore evaluated a motility capsule for continuous intra-abdominal pressure measurement in an animal model with a high probability for capillary leakage and intestinal edema. Motility capsules were inserted into the stomachs of 8 ...

OBJECTIVE:: Intra-abdominal hypertension is common in critically ill patients and is associated with increased morbidity and mortality. In a previous experimental study, positive end-expiratory pressures of up to 15 cm H2O did not prevent end-expiratory lung volume decline caused by intra-abdominal hypertension. Therefore, we examined the effect of matching positive ...

Aortic-brachial pulse pressure amplification (PPA) is a measure of arterial elasticity and it is also an independent cardiovascular risk factor. The PPA is mainly determined by age, height, central and peripheral pressure waveforms characteristics, including measures of arterial stiffness and wave reflection. In this study, however, we demonstrate that PPA ...

The external pumping action in CPR should generate sufficient flow and pressure, but the pump must also be 'primed' by ongoing venous return. Different additions to standard CPR are in use just for this purpose. Active decompression of the thorax (ACD-CPR) to 'suck in' venous blood has proven successful, but, ...

OBJECTIVE: Pressure recovery results in Doppler gradients greater than catheter gradients and is well established in association with bileaflet mechanical aortic valves. Because pressure recovery is influenced by orifice geometry, it might manifest differently with various valve prostheses. If true, then the reliability of Doppler echocardiography for the estimation of ...
