    1 expansion
    metered-dose inhalers
  39. these devices are available to be used w/ MDI devices and attach directly to the MDL. they increase delivery of the drug to the lungs and decrease deposition of the drug on oropharyngeal mucosa. some of these devices contain one-way valves that activate upon inhalation, so a person needs good hand-lung coordination. some of the devices have alarms that'll sound when inhalation is too rapid
