PURPOSE: We determined instances of aspiration in adults with tracheostomies and investigated the effect of the Passy-Muir tracheostomy speaking valve on occurrences of aspiration. METHODS: Adults with tracheostomies scheduled for videofluoroscopic swallowing examinations who met inclusion criteria were enrolled. According to study protocol, 6 presentations of thin liquids were recorded, 3 with and 3 without the Passy-Muir tracheostomy speaking valve. If a cuffed tube was present, the cuff was deflated fully for all presentations. RESULTS: Seven of 15 subjects aspirated material on 1 or more presentations of thin liquid. Five subjects aspirated material only with the Passy-Muir tracheostomy speaking valve off, whereas 2 subjects aspirated material with and without the valve. No subject aspirated material while the valve was on exclusively. Aspiration was significantly less frequent with the Passy-Muir tracheostomy speaking valve on than with it off. CONCLUSIONS: Clinically unapparent aspiration occurs commonly in patients with tracheostomies. An expiratory occlusive valve can reduce, though not eliminate, occurrences of aspiration. CLINICAL IMPLICATION: The benefit of the Passy-Muir tracheostomy speaking valve should be evaluated in selected patients who aspirate liquid.
