Various techniques have been used to detect apnoeas /hypopnoeas, including analysis of the pressure generated in the anterior nares through standard nasal cannulae, detection of differences between maximal inspiratory and expiratory flow and the use of pneumotachographs (26,27).
In the present study, measurements were conducted over a period of > 1 year using heated pneumotachographs. Instruments were carefully volume-calibrated at frequent intervals in both studies, but we cannot completely exclude that some drift over the long study period may have occurred within the calibration limits that may have obscured exposure-related differences in lung function, because it was logistically impossible to study the schoolchildren in random order.
In general, pneumotachographs have much faster frequency responses and are either disposable or very easy to clean.
Spirometers can be divided into volume displacement devices and pneumotachograph devices.
