hypostatic pneumonia n.
Pulmonary congestion due to the stagnation of blood in the dependent portions of the lungs in old persons or in those who are ill and lie in the same position for long periods.
The fatal issue is often hastened by the onset of hypostatic pneumonia.
It may arise from inhalation, or may be due to the dorsal position (hypostatic pneumonia), or it may arise from infection.
The lung in hypostatic pneumonia, even when it is inflated, still feels firmer between the fingers than normal lung.
