The effects of atelectasis on pulmonary gas exchange were studied in eight supine, clinically lung-healthy patients. Atelectasis was studied by computerized tomography (CT), and gas exchange by blood gas analysis. The distribution of ventilation/perfusion ratios was assessed by a multiple inert gas elimination technique. No patient had any signs of atelectasis in the awake state, and gas exchange was normal. During ketamine anaesthesia and spontaneous breathing, lung ventilation and perfusion… CONTINUE READING
