Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will discuss about the classification of asthma without any investigative tools in this video. He will explain that we can diagnose the severity of asthma patient on phone by asking him to speak. If the patient can speak the whole sentence, then it’s a mild asthma. If the patient breaks his sentence into two or three, then it’s a moderate asthma. And if the patient breaks a sentence in every word, then it’s a severe asthma.
