Hypoxic pulmonary vasoconstriction in reptiles: a comparative study of four species with different lung structures and pulmonary blood pressures
(Amer Physiological Soc, 2005-11-01)
Low O-2 levels in the lungs of birds and mammals cause constriction of the pulmonary vasculature that elevates resistance to pulmonary blood flow and increases pulmonary blood pressure. This hypoxic pulmonary vasoconstriction ...

Echocardiographic Doppler estimation of pulmonary artery pressure in critically ill patients with severe hypoxemia
(2008-01-01)
BACKGROUND: In spontaneously breathing cardiac patients, pulmonary artery pressure (PAP) can be accurately estimated from the transthoracic Doppler study of pulmonary artery and tricuspid regurgitation blood flows. In ...

Pressure support ventilation and biphasic positive airway pressure improve oxygenation by redistribution of pulmonary blood flow

Age and Method-dependent Variability of Predicted Oxygen Consumption in Congenital Heart Disease
(WILEY PERIODICALS, INC, 2009)
Background and Purpose. There has been a lot of debate about the use of predicted oxygen consumption to calculate pulmonary vascular resistance using the Fick principle. We therefore comparatively analyzed predicted oxygen ...
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 ...
Vagal tone regulates cardiac shunts during activity and at low temperatures in the South American rattlesnake, Crotalus durissus
(2016-12-01)
The undivided ventricle of non-crocodilian reptiles allows for intracardiac admixture of oxygen-poor and oxygen-rich blood returning via the atria from the systemic circuit and the lungs. The distribution of blood flow ...
