Restoring speech in persons who are tracheostomy and ventilator dependent, through the use of a Passy-Muir Speaking Valve (PMSV), requires specific training. Methods of training interprofessional team members to assess in-line PMSVs are unclear. This study used a pretest/ post-test design to compare effects of online training and online training plus simulation training on knowledge acquisition, skills performance, and comfort levels when working with persons who are tracheostomy and ventilator dependent. Twenty-six students studying either respiratory therapy (N=13) or speech-language pathology (N=13) were assigned to the control group or experimental group. Results revealed that online training proved beneficial for increasing tracheostomy and ventilator knowledge. Participants who underwent simulation training reported greater levels of comfort and demonstrated more efficient skills performance during simulation post-testing. Simulation training is efficacious to train interprofessional teams how to properly assess this population for use of in-line PMSVs.
