Shawn's girlfriend drove him to the emergency room when his wheezing was unresponsive to his fluticasone/salmeterol (Advair) inhaler. Shawn was unable to lie down and began to use accessory muscles to breathe. Shawn is immediately started on 4 L oxygen by nasal cannula and intravenous (IV) D5W at 75 mL/hr.
