Flow parameters are obtained from a volume-based spirometer by:
A) Multiplying by the STPD correction factor
B) Integrating flow by volume
C) Subtracting the BTPS correction factor
D) Measuring the volume displaced per second

Question

Quizplus · Accepted Answer

Flow parameters are measured by determining the volume displaced per second, which is done using a volume-based spirometer. Choice A is incorrect because STPD correction factor is used to convert volumes and pressures to standard temperature and pressure, and not for obtaining flow parameters. Choice B is incorrect because integration of volume by flow would give the total volume, not the flow parameters. Choice C is incorrect because BTPS correction factor is also used to convert volumes and pressures to body temperature and pressure.
