The purpose of this study was to ascertain the normal relation of swallowing apnea (SA) onset relative to lingual bolus propulsion along with factors that may alter this relation. Forty adults, composed of 10 men and 10 women in each of 2 age groups (i.e., 20–30 and 63–79 years) participated. SA onset was assessed during 5- and 20-ml bolus volumes of water and apple juice across 3 trials. The effects of age, gender, bolus volume, bolus viscosity, and gustation on SA onset relative to lingual bolus propulsion were examined. A significant interaction of Age × Gender × Volume was found. In general, older adults initiated SA onset earlier than young adults, and large boluses elicited an earlier SA onset than small boluses regardless of group. Young men demonstrated significantly later SA onset than the older men for large volumes; this difference was not observed for small volumes, nor was it found between young and older women. SA onset also was assessed during 5-ml bolus volumes of thin apple juice, thick apple juice, and applesauce across three trials. A significant main effect of viscosity was found revealing that SA onset was initiated later as bolus viscosity increased. Thus, the results of this investigation provided data on the relation of SA onset relative to lingual bolus propulsion in individuals with normal swallowing and how this relation changes as a function of age, gender, bolus volume, bolus viscosity, and gustation.

The coordination of swallowing and respiration, as measured by nasal airflow, and the effect of changes in the volume of the swallow bolus (0-20 ml) were investigated in 12 normal subjects. Both nonbolus and bolus swallows were usually preceded and followed by expiratory airflow. Swallows followed by inspiratory airflow accounted for 20% of nonbolus swallows but decreased further in frequency in the presence of a bolus. Swallowing was associated with an apneic period lasting 1.90 +/- 0.26 s for nonbolus swallows. Based on the apneic period response to bolus volume, the subjects were divided into two groups. The apneic period decreased by 60% in seven of the subjects regardless of bolus volume. The remaining five subjects gradually increased swallow apnea as bolus volume was increased. At larger bolus volumes, the latter group also exhibited an earlier onset of the swallow apnea and an increase in the number of swallows preceded by inspiration. The duration of the swallow-associated respiratory cycle was similarly prolonged by an increase in bolus volume in both groups. The results indicate that the respiratory pattern associated with swallowing is modulated by the volume of the swallow bolus. Within the normal population, at least two different patterns of response to bolus volume are identified.

Effects Of Aging

The effects of aging, tachypnea, bolus volume, and chronic obstructive pulmonary disease on the coordination of swallowing with the phases of respiration were studied by concurrent respirography and submental surface electromyography. Study findings showed that in young healthy volunteers, during rest, there is preferential coupling of subconscious swallowing with the expiratory phase of continuous respiration. This preferential coupling of swallowing with expiration was found to increase relative to other phases of respiration during water swallows and tachypnea (P < 0.05). Respiratory phase occurrence of swallowing and postdeglutitive resumption of respiration during exacerbation of chronic obstructive pulmonary disease was found to be significantly different compared with the basal state (P < 0.05). Respiratory phase occurrence of subconscious swallowing in the elderly was found to be different from the young (P < 0.05). Position had no significant effect on the coordination of swallowing and phases of respiration. We concluded that in resting young volunteers the majority of deglutitions are coupled with the expiratory phase of swallowing. This coupling is increased in frequency by the presence of a liquid bolus and tachypnea. And finally, age and chronic obstructive pulmonary disease alter this coordination significantly.

Swallowing Apnea

Objectives: The relationship between breathing and swallowing is very dynamic during swallowing and these are highly temporally coordinated to protect the airway. The ability to protect airways during swallowing deteriorates with aging. In this study, we attempted to compare the breathing-swallowing pattern and temporal change in the respiration and swallowing coordination between young and elderly adults in Korea.Methods: A total of 80 normal people, including 40 young and 40 elderly people participated in this study. For measurement of breathing and swallowing coordination, Digital Swallowing Workstation<sup>TM</sup> was used during a 5 mL water swallowing task. Temporal parameters related to breathing-swallowing including AS (acoustic start), AP (acoustic peak), AD (acoustic duration), SAS (swallowing apnea or respiration pause start), SAD (swallowing apena duration), sES (submental sEMG start), sEP (submental sEMG peak), sED (submental sEMG duration). Additionally, DHI (Dysphagia Handicap Index) was evaluated for self-assessment of the degree of difficulty swallowing.Results: Older adults displayed delayed swallowing-related acoustic signal measurements, swallowing apnea measurements, surface EMG measurements, and delayed sequential coordination time of swallowing-related structures during swallowing. There were no significant differences according to gender. Furthermore, a significant positive correlation was observed between the total K-DHI scores and as well as swallowing apnea duration in the elderly.Conclusion: In the older population, the different breathing-swallowing pattern from that of young adults may increase the risk of dysphagia. In addition, swallowing delays due to aging can be an indicator of elderly swallowing disorders. Moreover, an increase in apnea time during swallowing may be a phenomenon that appears as a mechanism for airway protection in the elderly. However, the high correlation between apnea time and K-DHI score in the elderly may make it difficult to maintain respiration for a long time during swallowing as the respiratory function decreases due to aging, which may increase the risk of experiencing symptoms such as choking and affect the degree of subjective swallowing disorder. This suggests that even if classified as a normal elderly person without a pathological swallowing disorder, swallowing training is needed to prevent swallowing disorders and to enhance swallowing ability for older people with degraded swallowing-related abilities.
