How long can a person survive asthma attack?

An asthma attack can range in severity from mild to life-threatening. In most cases, asthma attacks can be treated with quick-relief medication and do not last more than a few minutes. However, more severe asthma attacks can require emergency medical treatment and may last for hours or even days. In rare cases, a severe asthma attack can be fatal. If you or someone you know is experiencing severe asthma symptoms, it is important to seek immediate medical attention.
