Pulmonary Arterial Hypertension.
New England Journal of Medicine, 2021Copyright © 2021 Massachusetts Medical Society. Pulmonary hypertension is a syndrome characterized by marked remodeling of the pulmonary vasculature and a progressive rise in the pulmonary vascular load, leading to hypertrophy and remodeling of the right

Physical Therapy, 1983
To the Editor: Jeffrey Falkel's review of the factors associated with amputation in patients with diabetes mellitus (Phys Ther 63:960–964,1983) was both thorough and well directed, particularly in its emphasis on atherosclerosis as the primary cause of blood flow obstruction. Like most reviews, however, Dr.

The pulmonary arterial pressure
American Heart Journal, 1949Abstract Measurements of the systemic and pulmonary arterial pressure in a reptile (turtle), mammal (dog), and bird (chicken) were used as a basis for a study of the comparative physiology of the lesser circuit. Data on the ventral aortic (pulmonary) pressure in the fish were available in the literature.

Optimal arterial blood pressure
Journal of Theoretical Biology, 1991Based on the principle of minimum power, a mathematical model of the functional state of the circulatory system is presented. The optimization model minimizes the power expenditure of the heart, bone marrow and the power expended in carrying blood.

Monitoring Pulmonary Artery Pressure
Critical Care Nurse, 1999cialist at UCLA Medical Center and assistant clinical professor at the UCLA School of Nursing in Los Angeles, Calif. A variety of backrest positions may be used that do not compromise the accuracy of measurements of pulmonary artery pressure. Backrest elevations of 0°, 30°, 45°, and 60° with the patient supine (back flat against bed surface) do not ...

Validation of brachial artery pressure reconstruction from finger arterial pressure
Journal of Hypertension, 2008Measurement of finger artery pressure with Finapres offers noninvasive continuous blood pressure, which, however, differs from brachial artery pressure. Generalized waveform filtering and level correction may convert the finger artery pressure waveform to a brachial waveform.

Nursing, 2019
The most common presentations of peripheral arterial disease are intermittent claudication and abdominal aortic aneurysm. In patients under 50 years of age the cause of disease is most likely to be genetic, congenital, immunological, infectious, or ...

Pulmonary Artery Pressure Monitoring
AACN Advanced Critical Care, 1993Critical care nurses often care for critically ill patients who require pulmonary artery catheterization. Nurses need an extensive knowledge base to understand the various technical and physiologic factors that may affect the accuracy of pressure measurements.

RR–arterial pressure variability relationships
Autonomic Neuroscience, 2001Methodological aspects of a causal black-box model of heart period/arterial pressure interaction, arterial pressure closed-loop regulation and respiration effects on both heart period and arterial pressure are revisited in the "time" (more exactly heart beat count) domain.

Pulmonary artery occlusion pressure
Intensive Care Medicine, 2003The bedside estimation of left ventricular (LV) performance of critically ill patients is an important aspect of the diagnosis and management of these patients. Ever since the introduction of the balloon flotation pulmonary catheterization, health care providers have used measurements of pulmonary artery occlusion pressure (Ppao) to estimate both ...
