Noninvasive ventilation (NIV) relies on the creation of consistent positive airway pressure that results in increased laminar flow, stenting open airways and eliminating dead space. This improves lung filling and directly increases minute ventilation by increasing functional residual capacity and tidal volume.
NIV is not a definitive airway, but can often be used to optimize a patient’s respiratory condition without intubation. This is especially useful in patients with do-not-intubate orders.
