[Evaluation of the diaphragm in patients with COPD (emphysema dominant type) by abdominal ultrasonography].

Unlabelled: The aim of this study was to clarify whether the diaphragm in patients with COPD (emphysema dominant type) can be evaluated by abdominal ultrasonography. We therefore established a method for diaphragm scanning: The dome of the right hemidiaphragm was detected by epigastric right oblique scan passing through the right edge of the inferior vena cava and the zone of apposition. Diaphragmatic flattening, correlation between the flattening and %FEV1.
