[Tests concerning aeration or ventilation modalities of voluminous emphysematous bullae (author's transl)]

The authors recommend the use of two functional tests to evaluate the aeration and ventilation modalities of large emphysematous bullae: diffusing capacity by apnea method and ventilation scintigraphs using Xenon 133. In 56 bullous emphysema cases studied, a favorable correlation was observed between the results provided by the two techniques.
