Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cardiothoracic surgical patients

Subjects will undergo one simultaneous instrumental examination of swallowing and concurrent monitoring of metrics of respiratory-swallow physiology. Research exam will be performed at bedside within Cardiac \& Thoracic Intensive Care Units during their early postoperative recovery.
