Summary of "Respiratory Phase and Lung Volume Patterns During Swallowing in Healthy Adults: A Systematic Review and Meta-Analysis."

Purpose The coordination of respiration with swallowing is critical for facilitation of airway protection and the efficiency of movements that propel ingested material through the upper aerodigestive tract. Confirmation of a predominant pattern in healthy adults provides a platform for comparison to aberrant patterns observed in the population with swallowing impairment (dysphagia). Method A comprehensive search of published research in MEDLINE via PubMed 1946-2018, Embase 1947-2018, and Proquest Dissertations & Theses Global 1861-2018 was completed. Results Thirty-seven articles meeting inclusion criteria were selected for data extraction, and the findings were reviewed. In addition, a meta-analysis of the data was completed. A significantly higher occurrence ( p < .001) of expiration prior to and following the swallow was found when compared to 3 other patterns. The predominance of the pattern was influenced by increases in bolus volume when controlling for participant sample size. Conclusion Determination of this predominant pattern provides a normative framework for evaluating respiratory-swallow coordination in adults across the age span and highlights the relevance for assessing and incorporating respiratory swallowing coordination during assessment and interventions.

Sequential liquid swallowing is a common daily occurrence during which coordination of deglutition and breathing would be highly regulated to avoid pulmonary aspiration and to maintain hematosis. We s...

Brain signatures associated with swallowing efficiency in older people.

Swallowing is a complex movement consisting of the sequential and orderly activation of the swallowing muscles. Neuroimaging evidence has revealed a complex cortical and subcortical representation of ...

Assessment of the influence of lung inflation state on the quantitative parameters derived from hyperpolarized gas lung ventilation MRI in healthy volunteers.

Medical and Biotech [MESH] Definitions

The physical or mechanical action of the LUNGS; DIAPHRAGM; RIBS; and CHEST WALL during respiration. It includes airflow, lung volume, neural and reflex controls, mechanoreceptors, breathing patterns, etc.

A respiratory function test that includes the maximal inspiratory pressure and maximal expiratory pressure. It is determined by SPIROMETRY that measures the patient's RESIDUAL VOLUME and TOTAL LUNG CAPACITY and assesses the strength of RESPIRATORY MUSCLES.

The lung volume at which the dependent lung zones cease to ventilate presumably as a result of airway closure.

Measurement of the amount of air that the lungs may contain at various points in the respiratory cycle.

The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung. (From Best & Taylor's Physiological Basis of Medical Practice, 12th ed, p562)
