Doppler Echocardiographic Indices Are Specific But Not Sensitive to Predict Pulmonary Artery Occlusion Pressure in Critically Ill Patients Under Mechanical Ventilation
(2021)
OBJECTIVES: The objective of this study was to prospectively evaluate the ability of transthoracic echocardiography to assess pulmonary artery occlusion pressure in mechanically ventilated critically ill patients.
DESIGN: ...
Pressure-flow-volume relationships in the pulmonary circulation of normal highlanders : effects of unilateral pulmonary artery occlusion, exercise, and hypoxia
(Progress in Respiration Research, 1975)
Sumary
Pulmonary blood volume in NHL is comparable to that in sea level residents.
In resting NHL, pulmonary hypertension is best explained by, structural changes
in pulmonary vessels. In NHL, exercise elicits a pulmonary ...
Effect of saline infusion for the maintenance of blood volume on pulmonary gas exchange during temporary abdominal aortic occlusion
(Associação Brasileira de Divulgação Científica, 2007-03-01)
We analyzed the effects of saline infusion for the maintenance of blood volume on pulmonary gas exchange in ischemia-reperfusion syndrome during temporary abdominal aortic occlusion in dogs. We studied 20 adult mongrel ...
Outflow occlusion for circulatory arrest in dogs
(Colégio Brasileiro de Patologia Animal - CBPA, 2009)
The purpose of this study was to evaluate the possibility of producing circulatory arrest by occlusion of the pulmonary trunk as an alternative to the venous inflow occlusion through the left hemithorax. Eight healthy ...
Physiological and clinical effects of diurnal noninvasive ventilation in hypercapnic COPD
(EUROPEAN RESPIRATORY SOC JOURNALS LTD, 2005)
To assess the clinical impact of noninvasive mechanical ventilation (NIMV) on stable hypercapnic chronic obstructive pulmonary disease, changes in exercise capacity, dyspnoea and simple physiological parameters were ...
Coronary to Bronchial Artery Fistula: Are We Treating it Right?
(H M P COMMUNICATIONSMALVERN, 2013-08-02)
Fistulas between coronary artery and bronchial artery may be present from birth, with few hemodynamic consequences, and may remain closed due to similarity of the filling pressures at these 2 sites.(1) They can also be ...
Online monitoring of pulse pressure variation to guide fluid therapy after cardiac surgery
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
BACKGROUND: The arterial pulse pressure variation induced by mechanical ventilation (Delta PP) has been shown to be a predictor of fluid responsiveness. Until now, Delta PP has had to be calculated offline (from a computer ...
