Measurements of vital capacity and total lung capacity were made on healthy men of heights up to 206 cm. (81 inches), extending previous measurements on boys and men of average height. In the range… Expand
Graded Pulmonary Vascular Changes and Hemodynamic Findings in Cases of Atrial and Ventricular Septal Defect and Patent Ductus Arteriosus
With use of a previously described system of grading, a study was made of the relation between each of the grades of hypertensive pulmonary vascular disease and the hemodynamic findings in the lesser… Expand
Effect of Acetylcholine on Pulmonary Vascular Resistance in a Patient with Idiopathic Pulmonary Hypertension
Necropsy studies in cases of pulmonary hypertension of unknown cause show structural changes in the pulmonary vessels that are called irreversible. Acetylcholine chloride was infused at a rate of 2… Expand
