Respiratory mechanics measured by a simple device.
A simple and inexpensive apparatus is described which permits the semi-automatic measurements of pulmonary dynamic compliance (Cdyn) and airway resistance (Raw) while rapid changes of these factors during the experimental induction of pneumopathies can be followed. A diaphragm is used as a pneumotachograph because it was found to be quite sensitive and pulmonary secretions did not disturb the measurements. Volume base line drift is prevented.
