If you're with someone who's having an asthma attack, the best thing for you to do is to stay calm and to help them out. Have them sit down. Sitting is the best position for them, rather than lying down. Find their inhaler. Often times they will have it on their person, or nearby. Give it to them to administer their own medication. It's easier for them to do. They're used to doing it, they know how to do it, they know when to breathe in to get the medicine into their lungs. Sometimes people will try to help and they'll just spray, spray, spray, and it's not in time with breathing. Don't be alarmed by how many puffs the person is taking. It may be more or less than you're used to seeing them take. Just let them do it and stay with them, reassure them, keep them safe. If their breathing does not return to normal, or if they're having increased difficulty in breathing, call 911 and get help right away.
