[|Human|] Hi, my dad is a heavy smoker. He is 69 years old. When he has a coughing fit, he isnt able to take a breath in. So hell bang on his chest until he can. Yesterday, he had another coughing fit, only this time he started to shake, or little jerks. Mom said his name, but he didnt respond, so she yelled it, and then he responded. I should also tell you that he is obese as well.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Chronic smokers are more prone for bronchitis (inflammation of airways). Bronchitis causes bronchospasm and this in turn causes cough, chest tightness breathlessness etc. So consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).PFT will not only diagnose bronchitis, but it will also tell you about severity of the disease and treatment is based on severity only. He will need inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). He should quit smoking as soon as possible. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
