A method for endotracheal intubation allows resuscitation of the patient to continue during intubation. A curved guide having a mask and a ventilation port is inserted into the patient's mouth and upper airway. The patient is initially resuscitated by supplying a flow of air / oxygen through the mask and simultaneously applying cardiac chest compressions. An endotracheal tube is inserted over the distal end of a fiber optic probe. Resuscitation continues without interruption while the fiber optic probe and endotracheal tube are advanced along the guide into the patient's airway, thereby allowing the physician to carefully guide the fiber optic probe and endotracheal tube to a position past the larynx while resuscitation continues.
