Y1 - 2024 N1 - T2 - Hung’s Management of the Difficult and Failed Airway, 4th Edition AB - Providing effective oxygenation and ventilation using a facemask is probably the single most important component of airway management. The ability to oxygenate and ventilate immediately, in almost any environment and potentially stabilize a critically ill patient makes face-mask ventilation (FMV) one of the cornerstone interventions with which all practitioners in the operating room, emergency department (ED), and prehospital environment must be proficient. FMV refers to the use of a bag-mask unit, most of which but not all have valves (in which case they are referred to as Bag-Valve-Mask units or BVMs) system/device to deliver gas rich in oxygen either passively or actively by manually ventilating the patient using a facemask interface. Examples of non-valved bag-mask devices include Mapleson E (Jackson Rees Modification of Ayres T-piece) and other t-piece occluding systems. Manual noninvasive ventilation also accurately describes the use of an FMV device to provide positive pressure ventilation (PPV). This should be differentiated from mechanical noninvasive ventilation, which also uses a facemask interface but provides respiratory effort assistance (PPV) delivered by specialized ventilator.
