I also find manual chest PT far more effective than the vest. Here's why:
1. Manual Chest PT forces me to stop every two minutes and cough. I find it is way to easy to go through a vest treatment without making myself cough.
2. The positions of manual CPT target specific lobes of my lungs, and use gravity to drain them. Sitting up straight in a chair for the vest does not help lower lobes drain at all.
3. My physical therapist can hit me much harder than the vest can, and all of the force is directed specifically, instead of diffused around my entire torso.
4. In terms of patient compliance, my PT shows up and removes any question of when or how long I'll do airway clearance. I've never had compliance problems, but it makes it easier for me to keep my routine if I have someone showing up every day. The vest doesn't do that.
In addition, as Melissa stated, you have to be able to find the vest setting that is most effective for you.... however, I have never met a CF dr., PT, or even Hilrom representative who could give me useful advice about how to do this. It is fine to tell an adult who knows their body well enough to figure out their "setting" but I do not see how this is possible when dealing with young children and asking them to figure out which setting is best for them.
Obviously, the vest is way more convenient than CPT, but I sincerely question any "research" showing that vest is more effective. I've read the "studies" conducted by the vest manufacturer, and have never seen a large, long term study. Most studies I've seen involve very small numbers of patients for a very short time period. The measures they use are questionable, and do not look at broader measures of patient health and outcomes.
I think it is funny when I hear things like "the vest works better except when I have an exacerbation" If CPT is better than the vest at dealing with exacerbations and getting you back to baseline, isn't it most likely that CPT is better at preventing exacerbations???
I know the vest is easier, and that its nice to be able sit at the computer while doing it, and its certainly easier for parents who would otherwise have to do CPT. However, for me personally, CPT is the most effective airways clearance tool I have.
One last point... a lot of people say they like the vest because it makes them more independent. In my view, independence comes from having the highest lung function possible... whether or not I need another person to help me get there is secondary. Everyone needs someone.
