Emergency airway management: common ventilation techniques.

Maintaining a patient's airway and facilitating breathing are the main priorities during any emergency situation in which breathing is compromised. The key to safe management of an airway is thorough assessment, primarily to ensure the airway is patent. In an emergency situation, a bag-valve-mask may be the most effective way to assist ventilation. If ventilation is required for prolonged periods in an emergency situation, then endotracheal intubation should be performed. This involves the placement of a cuffed, endotracheal tube in the trachea, through which ventilation is maintained. Each tracheal intubation event should be anticipated as a potentially difficult intubation. Longer term ventilatory support may be achieved by the use of mechanical ventilators, which are designed to assist the movement of gases (air) into and out of a patient's lungs, while minimising the work and effort of breathing. This article provides nurses with an overview of the techniques and equipment that is most often used within emergency and intensive care units to maintain the patency of a patient's airway and provide ventilatory support.
