Maintenance of an unobstructed airway and administra tion of controlled ventilation by face mask can save the life of the patient unable to sustain adequate spontane ous ventilation. Techniques for obtaining an unob structed airway are reviewed, as are methods of posi tioning and holding the face mask. Breathing bag systems used to deliver supplemental oxygen and posi tive-pressure ventilation to the nonintubated patient are discussed.
