Sc. Tarrant et al., COMPARATIVE REVIEW OF TECHNIQUES FOR RECORDING RESPIRATORY EVENTS AT REST AND DURING DEGLUTITION, Dysphagia, 12(1), 1997, pp. 24-38
The coordination between swallowing and respiration is essential for s
afe feeding, and noninvasive feeding-respiratory instrumentation has b
een used in feeding and dysphagia assessment. Sometimes there are diff
erences of interpretation of the data produced by the various respirat
ory monitoring techniques, some of which may be inappropriate for obse
rving the rapid respiratory events associated with deglutition. Follow
ing a review of each of the main techniques employed for recording res
ting, pre-feeding, feeding, and post-feeding respiration on different
subject groups (infants, children, and adults), a critical comparison
of the methods is illustrated by simultaneous recordings from various
respiratory transducers. As a result, a minimal combination of instrum
ents is recommended which can provide the necessary respiratory inform
ation for routine feeding assessments in a clinical environment.
