Are interfacility ground transports of patients utilizing intra-aortic balloon pumps safe?
Although a few adverse events occurred, interfacility ground transport of patients with intra-aortic balloon pumps was not associated with morbidity or mortality in this study.
After pulmonary artery occlusion or lung collapse, adenine nucleotides are preserved if ventilation is continued. The increased permeability of rabbit lungs after 24 h of left pulmonary artery occlusion alone cannot be explained on the basis of depletion of high-energy phosphates. In the absence of ventilation due to lung collapse, pulmonary artery occlusion results in decreased adenosine triphosphate concentrations, demonstrating that the residual circulations (bronchial and pulmonary venous flow) are inadequate to support normal lung aerobic metabolism.
