Start by explaining the procedure to the patient, and obtaining consent to do it if available from the patient or family, and then positioning the bed to 0°, and sedating the patient, if the environment and equipment permits. Now tilt back the patients head, and using a laryngoscope visualize the vocal box, and insert the tube into the airway, guiding it with the laryngoscope, towards the vocal box, but not at it. Now attach a Endotracheal Tube Cuff to the end of the tube, and attach means of ventilation to it, such as Manual bag valve ventilation, or automatic, machine assisted ventilation
