Uneven distribution of exogenous surfactant contributes to a poor clinical response in animal models of respiratory distress syndrome. Alveolar recruitment at the time of surfactant administration may ...

A pulmonary gas sample is collected in a 50-ml. to 100-ml. Lucite chamber (Fig. 1 and 2) fitted with a sturdy, light anaeroid vacuum gauge and with thin, unidirectional "J" valves set in parallel at ...
