A method for holding an endotracheal (“ET”) tube on a patient which securely holds the ET tube and enables a healthcare provider to quickly and easily move the ET tube laterally at various positions. The ET tube can be secured to a carriage that slides laterally and can optionally be stopped at one or more predetermined locations, which predetermined locations can optionally be noted with unique identifiers which enable the healthcare provider to accurately document the position of the ET tube. A foam layer is preferably provided to keep rigid plastic components from applying directly contacting and directly applying pressure to the patient’s skin.
