Desenvolvimento e avaliação de um sistema experimental para treinamento no uso do laringoscópio

Abstract

This study presents the development of an experimental system based on a strain gauge integrated into the hook of a laryngoscope, aimed at monitoring electrical signal variations associated with force application during simulated orotracheal intubation. The project addresses the need for tools that provide objective feedback in medical training, supporting technical improvement and procedural safety. The methodology involved the selection and integration of electronic components, data acquisition via microcontroller, and statistical analysis using linear regression. Tests conducted with known weights revealed a strong linear correlation between the applied load and the system’s electrical response, demonstrating stable and reproducible measurements. The results indicate that the developed prototype is technically viable for use in simulated training scenarios, offering quantitative support for assessing performance in laryngoscopy
