PY - 2017 T2 - Hung's Difficult and Failed Airway Management, 3e AB - Providing effective ventilation and oxygenation using a bag mask is probably the single most important component of airway management. Bag-mask-ventilation (BMV) 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 face-mask interface. Examples of non-valved bag-mask devices include Mapleson E (Jackson Rees Modification of Ayres T-piece) and other t-piece occlude systems. Manual noninvasive ventilation also accurately describes the use of a BMV device to provide positive pressure ventilation (PPV). This should be differentiated from mechanical noninvasive ventilation, which also uses a face-mask interface but provides respiratory effort assistance (PPV) delivered by specialized ventilator.
