Asthma attacks can vary in severity and can range from a tense situation into an urgent one, or even a full on emergency. Like any emergency, the first thing to do is to remain calm and assess the situation. If the reason for the asthma attack is obvious, such as a smoky room, try to remove the person having the attack, or if possible, the trigger. Your next course of action will depend on the severity of the attack. Additionally, if there has been a series of attacks in close procession, you may need to seek immediate medical care.
