I agree with swmn, you need to check the o2 levels, seek a Pulmonary Doctor for this, plus sleep study will probably come into the picture, also. A neurologist familiar with
ALS will probably refer you to the Pulmonary Doctor for a work up on the levels.
Breathing issues with
ALS are very important, as the oxygen levels change when we go to sleep and your husband may need adjustment with a Bi-Pap machine.
You are in our thoughts and prayers, but seek help.
