The use of a threshold device to induce intraluminal airway pressure splinting has the potential advantage of generating an intraluminal pressure that is a function of the device, which means that intraluminal pressure is maintained at the set threshold pressure throughout the expiratory cycle, generating higher airway expiratory pressures, reducing airway collapse and DH, and thus possibly reducing dyspnea.
