    However, most MBW systems similarly incorporate main- and side-stream sensors with pre- and post-capillary compartments for N 2 MBW or sulfur hexafluoride MBW measurements [7, 20, 25], and are thus prone to similar leaks. Another limitation of our study was the difficulty of modelling leaks during inspiration.
