Airway patency via mechanical splinting during expiration

Airway patency via mechanical splinting of airways during expiration" refers to a **physiological/mechanical process** rather than a discrete molecular target. This approach is most commonly achieved using devices such as **Continuous Positive Airway Pressure (CPAP)**, **Bilevel Positive Airway Pressure (BiPAP)**, and **Positive Expiratory Pressure (PEP) devices**. These interventions work by applying positive pressure within the airways during exhalation, which acts as a "splint," mechanically holding the upper and lower airways open and preventing their collapse—especially in conditions like obstructive sleep apnea or bronchiectasis[1][3][6]. The mechanism does not involve direct interaction with receptors, enzymes, ion channels, or other classical drug targets; instead it is an application of physical principles to maintain airflow. Because this entry describes a therapeutic *strategy* rather than a molecule/receptor/protein/gene/ion channel/transporter/etc., it should not be considered a canonical therapeutic target in the conventional sense. There are no specific drugs that interact directly with this "target"; instead, various medical devices achieve the desired physiological effect through mechanical means. If you are seeking structured information on actual molecular targets involved in regulating airway tone or collapsibility—such as muscarinic acetylcholine receptor M3 for bronchoconstriction/bronchodilation—those would be more appropriate entries for canonical drug targets.
