Use of pulse pressure method for estimating total arterial compliance in vivo.
We determined total arterial compliance from pressure and flow in the ascending aorta of seven anesthetized dogs using the pulse pressure method (PPM) and the decay time method (DTM). Compliance was determined under control and during occlusion of the aorta at four different locations (iliac, renal, diaphragm, and proximal descending thoracic aorta). Compliance of PPM gave consistently lower va...
متن کاملSurrogate Measures for Providing High Frequency Estimates of Total Suspended Solids and Total Phosphorus Concentrations
Surrogate measures like turbidity, which can be observed with high frequency in situ, have potential for generating high frequency estimates of total suspended solids (TSS) and total phosphorus (TP) concentrations. In the semiarid, snowmelt-driven, and irrigation-regulated Little Bear River watershed of northern Utah, high frequency in situ water quality measurements were recorded in conjunctio...
متن کاملAge-related abnormalities in arterial compliance identified by pressure pulse contour analysis: aging and arterial compliance.
The objective of this study was to evaluate age-related changes in pulsatile arterial function. Aging alters arterial pulsatile function and produces consistent changes in the pressure pulse contour. A reduced systemic arterial compliance that can be derived from analysis of the pulse contour is regarded as the best clinical index of impaired pulsatile arterial function and may mark the presenc...
متن کاملTotal arterial compliance estimated by stroke volume-to-aortic pulse pressure ratio in humans.
On the basis of the windkessel model, the stroke volume-to-aortic pulse pressure ratio (SV/PP) has been proposed as an estimate of total arterial compliance, but recent studies have questioned this approximation. Aortic pressure was obtained at rest in 31 adults undergoing cardiac catheterization (47 ± 14 yr): controls ( n = 7), patients with dilated cardiomyopathy ( n = 10), and patients with ...
متن کاملArterial Blood Oxygen Saturation during Blood Pressure Cuff-induced Hypoperfusion
Pulse oximetry has been one of the most significant technological advances in clinical monitoring in the last two decades. Pulse oximetry is a non-invasive photometric technique that provides information about the arterial blood oxygen saturation (SpO2) and heart rate, and has widespread clinical applications. When peripheral perfusion is poor, as in states of hypovolaemia, hypothermia and vaso...
