My father suffered from severe bronchitis and pneumonia. He is now back home after 10 weeks of hospitalization. What type of therapy would he have?
He could benefit from using a flutter valve or also called as Acapella device to mobilize his pulmonary secretions. This a handheld non-electrical, or battery operated equipment. It purely is patient effort. If he's still short of breath, he can use nebulizer treatments as needed. You would need prescription for the above from your pulmonologist or primary physician.
I hope this helps you.
