Understanding the Chaos of Dysphagia and Aspiration

 Wednesday, March 6 ,2019

10:00-11:30 a.m.

In this session, the attendee will understand how different types of aspiration mechanisms exist with relevance to pathophysiology and management implications. When is aspiration a normal fact and when abnormal will be discussed. (each presentation is 20 minutes)


Bonnie Martin-Harris, PhD, CCC-SLP, BCS-S


Natural History of Patients who Aspirate: Is It Time to Develop Better Predictors?

Jonathan Bock, MD

This presentation will offer a discussion into the diagnosis of aspiration using VFSS, PAS scale, natural history and predictors of outcomes

After this presentation, attendees will be able to:

  • Understand the predictive ability of swallow studies to determine aspiration risk.
  • Evaluate mortality over time in patients with aspiration.
  • Discuss effects of diet modification on aspiration.


Feeding Through the Diagnosis of Aspiration: When to Feed and When to Pause?

James Coyle, PhD, CCC-SLP, BCS-S

Aspiration can be silent and deadly. This presentation will describe when to make the right decisions to feed or not to feed. A discussion into critical observations at evaluations will be undertaken as well as the consequences of silent aspiration.

After this presentation, attendees will be able to:

  • Understand and navigate the uncertainty surrounding potential risks of dysphagia.
  • Identify surrogates for silent aspiration and signs that indicate different risk levels.


Integration and Cross-Talk Between Deglutition and Respiratory Function

David McFarland, PhD

This presentation will discuss the synchrony between swallowing phases and breathing is a critical function to maintain feeding normalcy in health or disease. A discussion into pharyngo-esophageal phases of swallowing and relationship with respiratory functions in normal and dysphagia will also be undertaken.

After this presentation, attendees will be able to: 

  • Identify optimal respiratory (and masticatory) swallowing coordination.
  • Discuss the physiological advantages this coordination provides.
  • Understand problems in coordination and how to improve optimal patterning. 


Physiology and Pathophysiology of Aspiration Prevention Mechanisms: Are We Failing to Recognize Them? 

Reza Shaker, MD

Aspiration happens, but along with it, integration of neuro-aero-digestive-pulmonary mechanisms exists. An in-depth understanding of the physiology and pathophysiology of these reflexes will be undertaken during this presentation.
