Alveolar Gas Exchanges and Atelectasis

Physiology Requirements of Gas Exchanges Solubility, Diffusion and Osmosis Solubility Coefficient Diffusion Pressure Osmotic Pressure The Dissociation Curve of Hemoglobin in Relation to Respiration The Regulation of Respiration and Circulation Composition of the Alveolar Air Venous Blood Experimental Technic Intrabronchial Cannulas Closed Chest Experiment Open Chest Experiment Material and Purpose of Investigation Problems Investigated Fate of Alveolar Air Entrapped in a Pulmonary Lobe After Complete Occlusion of Corresponding Bronchus Changes Produced in Entrapped Alveolar Air as Indicated by Successive Gas Analysis Is Entrapped Air Absorbed and at What Rate? Speed of Absorption of Gases of Alveolar Air Introduced Individually in Atelectatic Lung of Living Animal and Gas Exchange That Takes Place Thereafter Results Following Introduction of Neutral Gases Separately Into Atelec tatic Lung Behavior of Respiratory Membrane Toward Anesthetic Gases or Vapors Changes, if Any, in Intrapulmonary Pressure in Occluded Lung During Process of Absorption Absorption of Various Gases by
