Alison... very good to hear... although Lesa may have a point as far as strength of cough goes as far as effectiveness...maybe Chris has a stronger cough...or maybe it is more effective combined with ventilation..just guesses on my part...
Anyway...if Chris develops problems later you may wish to look into the cough assist..however if the vest is working for him at this point it may not be neccessary...
Lesa ..again very good to see you as well...How are things going for you guys ? ...
