That’s why we use the regular cannulas, cratzer. The pressure transducer is so sensitive that we’re seeing some slight deflection even with most mouth-breathers. And the backup thermistor catches the mouthbreathers that don’t leave a pressure trace. It’s not any more invasive than the Nasal / Oral cannula. If your lab is progressive enough to go with the nasal / oral canns despite the increased cost, good for you. I guess my boss is Ol’ scrooge himself 😉
