All of the following statements are important ATS instrument specifications except: A) Back pressure and resistance must be less than 1.5 cm H₂O/L/sec up to an air flow of 14 L/sec. B) Spirometer must be capable of measuring volumes of at least 8 L (BTPS)with flows between zero and 14 L/sec. C) The paper must move at a chart speed of at least 32 mm/sec. D) Spirometer must be capable of measuring expired volumes for at least 15 seconds.

Question

Quizplus · Accepted Answer

The specification about the paper moving at a chart speed of at least 32 mm/sec is not directly related to the core functionality or accuracy of an ATS (American Thoracic Society) instrument for lung function testing. The other options (A, B, D) are directly related to the instrument's ability to accurately measure lung volumes and flows, which are critical for pulmonary function tests.
