Hi thomason, just saw your post. I turn age 80 this year, have had asthma since age 2. My “peak” on a peak flow meter (range 0 to 800) has never, ever gone higher than 300. I use a really cool battery power pocket inhaler/nebulizer containing a vial of Albuterol abt 4 times per day. It has a 3” spacer. But I only take ONE puff though doc said to use full vial. I also take one puff of Symbicort morning and evening. I find that using a full vial of Albuterol speeds me up too much. I also take a puff abt 2:30 AM when I have take my dogs out. I am a choral singer and am learning “belly breathing” which pulls the diaphragm down, bringing in more air. Belly breathing involves sucking in as much air as possible, even if you think you’ll bust (!) and holding it in as long as possible! Apparently I’ve been shallow breathing for all my life. Belly breathing definitely helps to get more oxygen which makes me feel a lot better. As for mucus, I buy a store brand (Walmart) mucus relief liquid (green label) and take an swig morning and evening. I also wear a Medic Alert wrist band that details my allergies, etc. I also have PMR. Hope my info is helpful to you. Cheers!
