A major weakness of asthma care is that many patients don’t know how to use inhalers to deliver life-saving medicine when they’re gasping for air. The fix may be as simple as taking more time to teach patients how the devices work, a U.S. study suggests.

Nearly all of the sickest asthma patients who wind up hospitalized when symptoms get out of control have no idea how to use inhalers to deliver what’s known as rescue therapy – fast-acting steroids that make it easier to breathe. The same is true of hospital patients with another common breathing disorder, chronic obstructive pulmonary disease (COPD).
