@grrranny I had just responded to your other post about hubby in the recliner. Since you mentioned he has pulmonary fibrosis, it would be good to consult his doctor about physical therapy. A PT can help a lot with issues of muscle tightness that restricts breathing. I just finished working with a PT and doing myofascial release for this because my ribs were not expanding enough. It can make a big difference. If I can’t move my lungs enough, it starts to trap phlegm which then turns into a chest infection. My allergies and asthma contribute to that. Tight muscles in the chest and neck and abdomen below the rib cage can impede full expansion of the rib cage and that is needed to create the negative pressure or “suction “ that inflates the lungs when you breathe. Does this make sense?
