Devices, systems, and/or methods for immobilizing a patient's head and simultaneously providing emergency respiration for the patient includes, in some embodiments, a head immobilizer, a bag valve mask (BVM), an endotracheal tube (ET) bracket, and/or an oxygen face mask. In some embodiments where head immobilization is not needed, a cardiopulmonary resuscitation (CPR) board may be used in lieu of the head immobilizer. Each such embodiment is configured to require reduced manual intervention by a caregiver without reducing the effectiveness of each medical device and/or system. An adjustable BVM holder integrated into the head immobilizer secures the BVM on the patient. In embodiments with a BVM, only a single hand is necessary to provide emergency respiration, freeing the caregiver's other hand for other caregiving tasks. Such a head immobilizer may secure an ET bracket and/or face mask to a patient, allowing for hands-free operation during patient treatment, movement, and transportation.
