Purpose: To examine pulse oximetry (PO) levels in healthy adult subjects across the adult age span, and to examine the same in a sample of individuals with severe and very severe
chronic obstructive pulmonary disease (COPD), and to compare their results. Method: PO levels were recorded via the BIOPAC Systems, Inc. (Goleta, CA) computer based data acquisition unit in
conjunction with the Acqknowledge version 4.1 software. Subjects for this study were drawn from a sample of 60 healthy young men and women between the ages of 18 to 38 (30 males and 30
females) and a sample of 60 healthy older men and women (30 males and 30 females) aged 60 years and over. A clinical population of 11 COPD subjects (3 males, 8 females) with an age range of
43 to 82 also participated in the study. Each subject swallowed 10 ml of water three times, 10 ml of applesauce three times, and three small individual pieces of diced pears three times.
Results: In the healthy adult group, a 2 (age) x 2 (gender) repeated-measures ANOVA revealed no statistically significant main effects for within-subject factors of bolus type or the
interactions of bolus x gender, bolus x age or bolus x gender x age. For between-subject variables there was no main effect for gender but age was significant F(1, 116) = 36.94, p < .001
and the interaction of gender x age was significant F(1, 116) = 5.62, p = .019. For the COPD sample, a Friedman test did not reveal statistically significant differences across the bolus
types. For the comparison between the healthy adults and COPD groups a Mann Whitney U test revealed that there were statistically significant differences between the groups for all the of the
bolus types: U = 22, p = .011 for water, U = 26, p = .023 for applesauce, and U = 22, p = .011 for pears. Conclusions: Our study contributed information regarding the invariant nature of PO
levels in healthy adult swallows across a range of consistencies (for a typical bolus volume). The same pattern was true for individuals with COPD. These results suggest that fluctuations in
PO values might indicate respiratory compromise, though additional investigation is warranted to confirm this hypothesis. / A Dissertation submitted to the School of Communication Science and Disorders in partial fulfillment of the requirements for the degree of Doctor of
