Tracheal intubation is the standard medical act to conduct airway management for artificial respiration. A laryngoscope and a tracheal tube are always used in that medical act. The way to prevent a complication while using a laryngoscope is only compassionate treatment from effectors. There are no objective guidelines of that medical act. When tracheal tube is inserted into the trachea to send air, it happens to be inserted into the esophagus by mistake. The incorrect intubation is very dangerous. In this paper, force sensor and two-axis gyroscope sensor are attached to the laryngoscope for making objective evaluations, and alarm buzzers beep to warn wrong laryngoscope actions. A field test was performed by using a training model, and the result was analyzed by principle component analysis to evaluate the degree of achievement and a personal characteristic. In addition, acoustic signals from a tracheal tube were examined as to whether insertion was correct or incorrect. Adaptive filter was used to reduce noises in the signals for enhancing estimated precision.
