It is demonstrated on theoretical grounds that the pressure dependence of resistance makes it unjustified to relate the slope of the pressure—flow relation to coronary resistance without taking the pressure dependence of resistance into account. The mechanisms impeding coronary flow and related to heart...
However, despite the fact that events occurring in the pulmonary capillary bed are also likely contributors to the overall shaping of the pressure/flow relation in the lung, the details of these contributions are not clear cut. For example, throughout the microcirculation, a number of closely ...

Mean detrusor pressure at maximum flow decreased from 64.7 to 39.1 cm. water, urethral resistance factor from 41.8 to 23.5 cm. water and linear passive urethral resistance relation from 3.0 to 1.4. Analysis of subgroups showed better results in patients with greater degrees of obstruction. ...
The measured pressure drop is monitored as a function of the imposed flow rate. For a given pressure drop, the corresponding flow rate in a deforming ... T Gervais,J El-Ali,A Günther,... - 《Lab on A Chip》 被引量: 413发表: 2006年 Flow rate-pressure drop relation for deformable ...
Long diastolic pauses, sufficient to allow coronary flow to reach zero, were produced by the cessation of electrical pacing.4. In the autoregulated coronary bed, Pf=0, 47 mmHg (s.e.m. = 9), exceeded subepicardial pressure at zero flow, 23 mmHg (s.e.m. =2; P < 0.001). During ...

The utility of combined oesophageal pressure–impedance recording has been enhanced by automation of data analysis. To understand how oesophageal function as measured by automated impedance manometry (AIM) pressure-flow analysis varies with bolus characteristics and subjective perception of bolus passage. Oe...
(a) when in the relation between flow and pressure measurement of the related pressure is expressed in units of flow (inferential), and (b) a vane or piston meter (absolute). For application in data-acquisition systems it is relevant to raise the question of analogue versus digital data-...
