Webexpressed in litres at BTPS. Equipment Requirements The spirometer must be capable of accumulating volume for o15 s (longer times are recommended) and measuring volumes of o8 L (BTPS) with an accuracy of at least ¡3% of reading or ¡0.050 L, whichever is greater, with flows between 0 and 14 L?s-1. The total resistance to airflow at 14.0 L?s-1 must WebAs such, a fixed volume of gas contains a different number of gas molecules, varying with temperature and pressure. To uniquely define a specific gas flow, which is a measure of a volume of gas per unit of time, it is ... (often equal to BTPS). In the absence of a humidifier, the lung would bring the gas to BTPS conditions and cause the gas to ...
