The inspiratory pressure trigger is essential when assessing the twitch mouth pressure (Tw Pmo) for avoiding glottic closure. However, the difference in inspiratory pressure trigger threshold may influence the values of Tw Pmo. We sought to determine the trigger threshold for healthy subjects and COPD patients.
