Threshold PEP

Threshold PEP is used for airway clearance, bronchial hygiene, or as an alternative to chest physical therapy. Threshold PEP incorporates a flow-independent one-way valve to ensure consistent resistance with adjustable specific pressure settings (in cm H2O) which are set by the healthcare professional. When patients exhale through Threshold PEP, the resistive load creates positive pressure that helps open the airways and allows mucus to be expelled during “huff” coughing (forced expiratory technique).
