Abstract

Purpose of Review

This review was designed to summarize our current understanding of optimal respiratory-swallowing coordination and to highlight a novel intervention to improve coordination in patients with dysphagia consequent to head and neck cancer and treatment. Additional consideration was given to the challenges of recording respiratory movements for clinical and research purposes surrounding respiratory-swallowing coordination.

Recent Findings

Our recent findings in normal humans reveal that the respiratory pause to accommodate swallowing interrupts quiet breathing in a restricted range of lung volumes from mid to low tidal volume. We have hypothesized that this “optimal” range imparts significant airway protective and physiological swallowing benefits. Systematic respiratory-swallow training in patients treated for head and neck cancer with refractory dysphagia and less than optimal patterning not only improved respiratory-swallowing coordination but also diminished aspiration and improved key components of swallowing physiology.

Summary

These data suggest that respiratory-swallow training may be an important treatment tool to re-establish respiratory-swallowing coordination and could be used in conjunction with other swallowing treatments to improve swallowing outcomes in susceptible patients. Future research is needed to explore mechanisms of change and to refine the treatment methodology to further improve swallowing outcomes.

Respir Physiol Neurobiol. 2016;234:89–96. This paper provides a very detailed assessment of normal respiratory-swallowing coordination. The restricted range of lung volumes observed in these subjects confirmed our earlier data suggesting that swallowing optimally occurs from mid to low quiet breathing expiratory lung volumes. It provided the training target, therefore, for the clinical trial used to improve coordination in head and neck cancer patients.
