Pressures in the pial arterial microcirculation of the cat during changes in systemic arterial blood pressure.
Dynamic arterial blood pressures were recorded by micropuncture of 99 cortical surface arteries and arterioles in cats anesthetized with pentobarbital or chloralose and urediane, using the Wiederhielm servocontrolled micropipette pressure system incorporating pipette tips less than 0.5/A in diameter. During these measurements, systemic blood pressure was varied by supplemental intravenous admin...

متن کاملRegulation of choroidal blood flow during combined changes in intraocular pressure and arterial blood pressure.
PURPOSE To test the hypothesis that human choroidal blood flow (ChBF) may depend, not only on ocular perfusion pressure (OPP), but also on absolute mean arterial pressure (MAP) and intraocular pressure (IOP). METHODS There were two study days in an open design. On the first day, OPP was varied by elevating IOP during a squatting-induced increase in MAP (28 subjects). On the second day, only t...
متن کاملTHE EFFECT OF ARTERIAL O2 SATURATION AND HE ART RATE ON BLOOD PRESSURE DURING HYPOXIA
A periodic increase in blood pressure (BP) occurs during apneic episodes in patients with obstructive sleep apnea (OSA). Several factors including hypoxemia and an increase in heart rate (HR) were reported to be responsible for this increased BP. To examine the contribution of these two factors in increasing BP, 35 healthy male subjects (mean age±SD= 23.64±3.80) were studied in three experi...
متن کاملEstimation of changes in instantaneous aortic blood flow by the analysis of arterial blood pressure.
The purpose of this study was to introduce and validate a new algorithm to estimate instantaneous aortic blood flow (ABF) by mathematical analysis of arterial blood pressure (ABP) waveforms. The algorithm is based on an autoregressive with exogenous input (ARX) model. We applied this algorithm to diastolic ABP waveforms to estimate the autoregressive model coefficients by requiring the estimate...
