Natural size. This functional model makes it possible to learn how to intubate under lifelike conditions. In its design and construction, special attention is paid to natural dimensions and anatomical features to develop functional models. If excessive pressure is applied to the upper incisor through the laryngoscope during intubation, an acoustic signal will be heard. The position of the catheter inserted after the intubation is correct, which can be confirmed by hearing breath sounds through the stethoscope on the left and right walls of the chest cavity.
