A facemask to abolish “difficult mask ventilation” in unconscious patients by viewing the wind pipe while delivering oxygen and incorporating channels on the facemask is described. The facemask makes it possible to oxygenate/ventilate an unconscious patient while securing a definitive airway by endotracheal intubation. The anesthetic facemask incorporates channels through which an ‘airway-slider’ fitted with a camera is inserted inside the patient's mouth, when the patient is unconscious. The airway-slider simplifies maneuvering the endotracheal tube into the patient's windpipe thus achieving a definitive clear airway with the use of just one device as opposed to the practice of needing multiple devices for the same in current anesthetic practice.
