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.

Pulmonary artery pressure and signs of right ventricular (dys)function are loosely related and should be independently evaluated. Systolic pulmonary artery pressure is best evaluated by peak velocity of tricuspid regurgitation. Acceleration of pulmonary artery flow and its morphology are useful to detect patients with pulmonary hypertension.

Pulmonary Perfusion Patterns and Pulmonary Arterial Pressure
Radiology, 2002To use artificial intelligence methods to determine whether quantitative parameters describing the perfusion image can be synthesized to make a reasonable estimate of the pulmonary arterial (PA) pressure measured at angiography.Radionuclide perfusion images were obtained in 120 patients with normal chest radiographs who also underwent angiographic PA ...

Pulmonary Artery Catheters and Assessment of Pulmonary Artery Wedge Pressure
Critical Care Nurse, 2014alliances and professional education at Edwards Lifesciences in Irvine, California. In a recent publication, the major area of decline occurred in nonsurgical intensive care units. Continued PAC use tends to be in surgical patients, those taking vasopressors, and those receiving mechanical ventilation.

Pulmonary artery pressure-directed therapies in pulmonary arterial hypertension?
Vascular Pharmacology, 2022Pulmonary arterial hypertension is a rare dyspnea-fatigue syndrome defined by an increase in mean pulmonary artery pressure above 20 mmHg combined with an increase in pulmonary vascular resistance higher than 2 Wood units. The condition is of poor prognosis and still incurable in spite of progress achieved in recent decades.

Increase in Pulmonary Artery Pressures
2020Pulmonary hypertension (PH) is common in systemic sclerosis (SSc), it is often suspected on the basis of echocardiographic findings—but false positives and false negatives are frequent. Prognosis is adversely affected by all conditions causing PH, early identification of both PH and the underlying cause is the key to optimising quality of life and ...

Optimal Pulmonary Arterial Blood Pressure
Journal of Theoretical Biology, 1993Based on the principle of minimum power, a mathematical model of the functional state of the pulmonary circulatory and respiratory systems is presented. The optimization model minimizes the power expended by the right heart and respiratory muscles. The pulmonary diffusing capacity control mechanism is considered.

Clinical Radiology, 1988
The pulmonary arteries dilate in response to many factors, principally increased pressure and flow. In patients who have pulmonary arterial hypertension but no increase in flow, we have compared main pulmonary artery size at computed tomography with pulmonary haemodynamic data obtained during right heart catheterisation.

Estimation of pulmonary artery pressure from pulmonary vein wedge pressure
Catheterization and Cardiovascular Diagnosis, 1994AbstractCorrelations between pulmonary artery and pulmonary vein wedge pressures were investigated in 13 patients with atrial septal defect and 1 patient with Tetralogy of Fallot. Pulmonary vein wedge pressure wave form resembled that of pulmonary artery pressure, and the former lagged behind the latter by 70 to 110 msec (mean 88 ± 14) as observed by ...

REGULATION OF PULMONARY ARTERIAL BLOOD PRESSURE
Archives of Internal Medicine, 1948SINCE Hering's discovery, 1 about twenty years ago, that increased pressure in the carotid sinus reflexly produces bradycardia and arteral hypotension, a great deal of work has been done in the regulation of systemic arterial blood pressure. It has been proved, especially by the work of Heymans and his associates, 1a that the sinus and aortic regions ...
