Helo.
Please read the whole thing. I need help
I am an 18 years old asmathic boy. 3 days ago i had serious asthma attack. I couldnt breath, so i started to breath improperly, with straining my shoulder muscles . Anyways i called anbulance and i was hospitalised. My PLUERA broke from heavy straining. So now my lungs have old gases in them. If they dont get out with breathing, and get replaced with new air i will need to have chest surgery which could be fatal.
Now the part where i need your help. I need breathing exercise that will help get that old air out, and get the new air in. Exercise should not include any body part movment, and should not include deep breathing.
Also if you know any type of food that helps tell me.
Ty in advance
