I know many of us wish that there was one way to do airway clearance. Unfortunately, there is not. Even when it comes to different breathing techniques including active cycle breathing and autogenic breathing, there are many varieties. What’s most important is to perhaps learn one of them and get comfortable with it. And then see if overtime see if it gets the job done. If not, switch to a variation on it or a different technique. And then of course, there’s combining different modalities in one session such as nebulizing, using an opep device like an Aerobika and let’s not forget postural drainage 🙂 I guess I’m saying the bottom line is airway clearance is as much an art form as it is a science. I hope this is helpful and not confusing, Linda Esposito
