Oxygen therapy is essential, with hypoxia being the leading cause of death in children with asthma. Oxygen therapy can be administered via a nasal canula or mask, although patients with dyspnea often do not like masks. With the advent of pulse oximetry, oxygen therapy can be easily titrated to maintain the patient's oxygen saturation above 92% (>95% in pregnant patients or those with cardiac disease).

In the event of significant hypoxemia, non-rebreathing masks may be used to deliver as much as 98% oxygen. Tracheal intubation and mechanical ventilation are indicated for respiratory failure.
