Brief summary
Dysphagia (swallowing impairment) is a common complication of cardiothoracic surgery (CS). Although alterations in respiratory-swallow coordination is a known underlying pathophysiologic mechanism of dysphagia in multiple patient populations, no group has examined respiratory-swallow physiology in CS patients. The proposed study will examine respiratory-swallow physiology in CS patients and determine its association with unsafe swallowing and inferior health-related outcomes.
Detailed description
The proposed study will examine respiratory-swallow physiology in cardiothoracic surgical patients and determine its association with unsafe swallowing and inferior health-related outcomes. Participation will involve a single postoperative research exam of approximately 60-90 minute duration. Participants will be seated upright and positioned for simultaneous instrumental imaging of swallow physiology, nasal airflow monitoring, and respiratory inductance plethysmography testing.
Interventions
DIAGNOSTIC_TESTVideofluoroscopic swallow exam with concurrent monitoring of respiratory-swallow coordination
Participants will undergo simultaneous videofluoroscopy, nasal airflow and respiratory inductance plethysmography testing.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Penetration Aspiration Scale | Up to 1 year | This scale is a validated measure used by trained blinded clinicians to assign ratings of safety to swallowing bolus trials. The development and use of an 8-point, equal-appearing interval scale (8 being best; 1 being worst) to describe penetration and aspiration events are described. Scores are determined primarily by the depth to which material passes in the airway and by whether or not material entering the airway is expelled. |
