An endotracheal tube alarm apparatus includes an inner cannula having an outer mating surface, the outer mating surface having a seated first electrical conductor, and a ventilator tube having an inner mating surface slidably coupled to the outer mating surface of the inner cannula, the inner mating surface having seated second and third electrical conductors extending circumferentially about the inner mating surface and each in complementary opposition to the first electrical conductor so that the third electrical conductor is in electrical communication with the second electrical conductor through the first electrical conductor.
