We describe a new method of measuring respiratory system compliance (Crs) that appears to detect whether respiratory muscles are relaxed. A pulse airflow, 0.3/s, is blown into the mouth through a pneumotachograph. Mouth pressure is recorded on the abscissa of an oscilloscope. Inflated volume, integrated from the flow signal, is recorded on the ordinate. After an initial step shift of pressure related to the flow resistance of the subject, pressure increases linearly at a rate inversely… CONTINUE READING
