Vascular Response in Dog Lung Induced by Alterations in Pulmonary Arterial CO₂ Tension and by Acetylcholine

Effects of 2‐amino‐2‐hydroxymethyl‐1, 3‐propanediol on the Pulmonary Hypertension of Hypercapnic Acidosis

“…Hg (range 13 to 31). Pulmonary "capillary" pressure increased from 8 (range 4 to 9) to 16 (range 12 to 18 mm. Hg.…”

“…The effects of inhaling carbon dioxide mixtures on the pulmonary circulation have been investigated by some authors with inconsistent r e s~l t s .~J Bean el aZ., 8 on the basis of observations on isolated vascular segments, Binet and Bo~rliere,~ and Duke,Io on special animal preparation, have suggested that the breathing of air enriched with C02 may elicit vasoconstriction. The effects of inhaling 5 per cent carbon dioxide in air on the pulmonary circulation were studied in humans by Fishman et aZ."…”

Respiratory Burns with Special Reference to Pulmonary Edema and Congestion

“…Our present information on pulmonary blood volume is based on direct measurements in perfused lungs,24, 25 and on estimates by dye dilution26-28 and by vital capacity29 in man. The radioactive technic has offered an additional means of supplementing our understanding of the pulmonary circulation.…”
