Dry powder inhalers (DPIs) require a rapid and deep inhalation by the patient and cannot be effectively used in-line with PEP devices, which are designed for controlled, positive pressure exhalation. Metered dose inhalers (MDIs) and small volume nebulizers, however, can be adapted for use with PEP devices, allowing for the simultaneous delivery of bronchodilator medication and PEP therapy.
