Parámetro acústico de la duración de la deglución en jóvenes universitarios en edades entre 20 a 25 años con el uso del sonar Doppler y el Software Deglutisom.

Abstract

INTRODUCTION: There are numerous methods for the exploration of swallowing alterations, some of the objective type and others of the subjective type. However, swallowing measuring devices have limitations in availability, poor safety and inconvenience as a result of quantitative testing. Doppler sonar has recently been suggested as a complementary method for clinical diagnosis that could constitute an early warning sys0074em for the identification of patients at high risk of aspiration and/or laryngeal penetration. It is based on the capture, storage and analysis of swallowing sounds during the pharyngeal phase. For the analysis, 3 acoustic parameters, intensity, frequency and time are taken into account. METHODS: Viscosity standardization was carried out, in addition the acoustic parameter of swallowing duration was analyzed in terms of gender, volume and viscosity. RESULTS: significant differences were evidenced in viscosities and volumes between genders, however, no significance was evidenced between viscosity and volumes by gender ANALYSIS AND DISCUSSION: The duration of the swallowing evaluated with Doppler sonar, depends on viscosity and fluidity, likewise its acoustic analysis has been performed with different software, which has provided different results in the last 20 years. CONCLUSIONS: The results found in this investigation differ from those reported in the literature possibly due to the size of the sample, the viscosities or the instruments used for the capture and analysis of the swallowing duration.
