Pulmonary Artery Pressure Studies Does Over-Distension of the Lung Cause Hypertension?

ARTHUR F. REIMANN M.D., F.C.C.P.1; EDWIN TUTTLONG M.D.1; WILLIAM B. ADAMS M.D., F.C.C.P.1; ANGELO K. OZOA M.D.1; and SALVATORE NIGRO M.D.1

Fifteen mongrel dogs were subjected to resections of 50 to 85 per cent of total pulmonary tissue. In the closed postoperative chest, pulmonary artery pressure was measured with the remaining lung in "normal" distension and over-distension.

The results obtained demonstrated that over-distension of residual normal lung does not aggravate any pulmonary hypertension produced by large pulmonary resections.

From the standpoint of pulmonary hypertension this experiment would indicate that collapse procedures to prevent over-distension of normal lung are unwarranted.
