Hi Linda, as I’m becoming more familiar with both MAC and bronchiectasis, I’m wondering if those who deal with either/both of these conditions find any benefit from using an incentive spirometer (used while inhaling) as well as using an Aeribika/Acapella device (OPEP) which exercises the lungs when exhaling. Seems like both devices may help with making it easier to cough up excess mucus/fluids from lungs, in addition to nebulizing hypertrophic saline. Although many hospitals provide patients with a spirometer to help them clear their lungs from fluids after surgery (since they likely have low oxygen levels and using a spirometer can help restore a normal oxygen level) it also seems that using an incentive spirometer can help prevent lung infections by expanding your lungs, strengthening your lungs, keeping your lungs inflated and clearing mucus and other secretions from your lungs. Just wondering if you/others here have tried and/or discovered any benefit from using a spirometer as an ongoing lung therapy device beyond just using a few days after surgical procedures? I’m trying to encourage my dad to use it since the hospital let him keep it after being discharged. They instructed him to take slow, deep breaths in, hold for 3-5 seconds then exhale normally. They said to do this 10x every hour and that it’s ok to take a break and breathe normally without the device in between the 10x if he wants. In other words, he doesn’t have to do 10x in a row since this may cause him to get light headed. Thank you in advance to you/others for any thoughts/experiences that you’d care to share here regarding spirometer treatment! Cheers, Scott
