A device and method for performing cardiopulmonary resuscitation (CPR) on a patient. The device is an extendable airway bridge which is initially in a collapsed or storage configuration. Upon use, the airway bridge is unfolded and then fixed into an operating configuration by locking at least one incline portion and at least one vertical portion into a static position. The structural strength of the airway bridge is then increased by manipulating a support disposed on the incline portion so that it is engaged with a slot or aperture defined within a base of the airway bridge. Once in the operating configuration, the patient is laid onto the airway bridge which holds the patient in a position so as to prevent occlusion of the patient's oral airway. CPR may then be performed on the patient.
