Hello I have a male friend who is 40 and smokes who suffered a asthma attck on last friday and is still in the hospital.  On last sunday he was put in a medically induced coma and i just wanted to know what your thoughts on the reason they put him in that state? He is to be relieved from it tomorrow.
Hi, Welcome to Chat Doctor, Thanks for the query, Asthma is a chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction and bronchospasm, mostly episodes comes in the nighttime. The chronic inflammation is associated with airway hyper-responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing particularly at night or in the early morning. Here, it could happen that your friend had an asthma attack, and he got severe breathlessness and did not get emergency treatment on time and went to deep hypoxia which may lead to temporary unconsciousness. This kind of coma like state is completely reversible with non-invasive ventilation or BiPAP for 2 days for which he must have given some temporary anesthesia. Hope this will help you.
