A Low-Cost, Force-Sensing Laryngoscope to Monitor Dental Force During Intubation Training

Effective airway management is crucial for patient safety, yet novice providers have not mastered the optimal technique to minimize the risks of complications such as dental injury. Training mannequins with force-feedback are slowly becoming available but are cost-prohibitive. We developed a low-cost, Arduino-based force-sensing laryngoscope that provides real-time auditory and visual feedback on dental force application. Among 28 learners, 89% found force-feedback beneficial for improving intubation technique. This system facilitates independent practice and remote supervision, offering a scalable alternative to high-cost mannequins. Future studies should evaluate its impact on skill retention and patient outcomes, optimizing laryngoscopy training in resource-limited settings.
