This research study is investigating the efficacy and implementation of expiratory muscle strength training (EMST), standard of care dysphagia treatment, and intensive dysphagia treatment in critically ill adults in the acute care setting. Currently, no targeted, effective, and feasible dysphagia treatment approaches currently exist for use in critically ill adults in the acute care setting. The current study will investigate the impact of EMST, standard of care dysphagia treatment, and intensive dysphagia treatment on pulmonary function, cough function, swallow function, frailty, patient-reported swallow function, and health outcomes in critically ill adults. This study will also examine patient perceptions and clinical speech-language pathologists' perceptions of the acceptability, appropriateness, and feasibility of these interventions.

Critically ill adults will: undergo tests of breathing, cough, and swallow function, complete questionnaires about the treatment, and their swallow function, and complete their respective treatment as prescribed.

Clinical speech-language pathologists will complete questionnaires about the interventions.

A subset of critically ill adults and clinical speech-language pathologists will also have the opportunity to participate in focus groups.
