PY - 2005 T2 - Principles of Critical Care, 3e AB - Many patients with ventilatory failure can be successfully managed with noninvasive positive pressure ventilation (NIPPV).NIPPV improves gas exchange, reduces the work of breathing, and relieves dyspnea.Patients most likely to benefit include those with acute hypercapnic exacerbations of chronic obstructive pulmonary disease (COPD) or hypercapnic forms of acute cardiogenic pulmonary edema.In selected patients with acute hypoxemic nonhypercapnic respiratory failure, NIPPV may obviate the need for endotracheal intubation. Selection may require exclusion of patients with hemodynamic instability, central neurologic dysfunction, or an inability to protect the upper airway.In severely hypoxemic patients, undiscerning use of NIPPV may inappropriately delay intubation. In these patients, the decision to switch to endotracheal intubation should be made early.The use of NIPPV to treat postextubation respiratory distress has not been found to be superior to conventional management.The first hour on NIPPV is crucial in predicting the outcome and requires that experienced physicians, nurses, or respiratory therapists spend considerable time at the bedside.A favorable response to NIPPV is usually apparent within the first hour. Absence of improvements in dyspnea, respiratory rate, and gas exchange within 1 hour strongly suggests a need for endotracheal intubation.Typical settings in a patient with COPD include pressure support of 10 cm H2O above a positive end-expiratory pressure (PEEP) of 5 cm H2O.In appropriately selected patients, NIPPV produces better outcomes than does endotracheal mechanical ventilation.
