1. The plethysmograph revealed decreased lung capacity.

2. Get more blood, a chest CT and a body plethysmograph.

3. The cathode-ray-tube display of a body plethysmograph is enhanced by a composite switching circuit, which displays an electronically generated angle cursor and plethysmograph parameters simultaneously on an accurate single beam oscilloscope.

4. The accuracy of the water and strain-gauge plethysmograph is identical, and the two instruments closely follow random variations in blood flow.

5. 17 Therefore photoelectric blood stream plethysmograph provide a modern technological platform for color-diagnostics of TCM, and deserve to popularize and apply.
