My Dad's Lung Condition

My dad has a serious lung condition. His lungs produce and trap an excessive amount of mucus. The trapped amount is huge and keeps his lungs from working correctly. Last week it was that time of the month when he couldn't breathe. I called an ambulance and he was brought to the closest hospital. Pretty normal for me because this happened at least ten times in the last six months. After I threatened them with calling the police and having a huge knife in my hand, they left.
