presented by Deanna Britton
Pulmonary function and pulmonary defenses are highly relevant to dysphagia assessment in adults. This course, with Deanna Britton, introduces key concepts regarding the clinical relevance of pulmonary function for speech language pathologists during dysphagia assessment, and describes key anatomy, physiology, and pathophysiology of the respiratory system. Anatomy will be broken down at a high level, including the features of the thoracic region, and at a cellular level, including alveolar function and gas exchange. After establishing key anatomical features, the course concludes by describing the mechanisms of breathing and pathophysiological processes associated with aspiration pneumonia and other conditions.
Deanna Britton is an Assistant Professor in the Department of Speech & Hearing Sciences at Portland State University (PSU), and Adjunct Assistant Professor at the Northwest Center for Voice & Swallowing in the Department of Otolaryngology (NWCVS) – Head & Neck Surgery at Oregon Health & Sciences University (OHSU) in Portland, Oregon. She is Board Certified in Neurogenic Communication Disorders in Adults by the Academy of Neurological Communication Disorders and Sciences (ANCDS). Dr. Britton has published and presented on topics related to dysphagia, dysarthria, augmentative and alternative communication, respiratory support for speech and swallowing, motor neuron disease, and spinal cord injury. Her research interests include respiratory support for swallowing and cough effectiveness.
In the first chapter of this course, Deanna Britton explains the importance of assessing pulmonary function within the context of dysphagia assessment by speech language pathologists.
In this chapter, Deanna Britton takes the student on a detailed tour of the thoracic region, including musculature and structures essential for pulmonary function. Key physiological processes essential for normal pulmonary function are also discussed.
In the final chapter of this course, Deanna Britton describes scenarios in which normal pulmonary function can be compromised, including aspiration pneumonia, pneumonitis, and other conditions related to injury or disease processes.
