Analysis Parameters for the Evaluative Interpretation of Pulse Oximetry in Swallowing

Abstract

Introduction: To contribute conceptually to the use of pulse oximetry as a complement to the assessment process, we sought to determine the analytical parameters that support the evaluative interpretation of pulse oximetry as an indicator of swallowing. Methods: This research aims to explicitly present the analytical parameters that support the evaluative interpretation of pulse oximetry as an indicator of swallowing. It is framed within a qualitative-quantitative experimental design executed through data collection, seeking to establish the time it takes for the pulse oximeter to desaturate during a period of apnea. This collection was performed on a university population affiliated with the Faculty of Health of the University of Pamplona. Results: One hundred normotypical subjects participated in this research; at the time of data collection, 18 participants were excluded from the test because they did not meet the inclusion criteria. Finally, 73 participants actively participated, and the average age of the study population was 22 years. Analysis: This study allowed us to establish parameters to be taken into account when using them during the swallowing assessment process, providing a measure that makes the diagnostic procedure more objective. Conclusions: For speech-language pathology assessment, indicators that quantitatively show functional parameters are important. These indicators do not base their diagnosis on the subjectivity of the protocol, but rather, through clinical evidence, indicate something beyond what is clinically observable.
