Noninvasive ventilation in acute cardiogenic pulmonary edema
New England Journal of Medicine, 2008 · Multicenter randomized trial (n=1069) comparing standard oxygen, CPAP and bilevel noninvasive ventilation.
Clinical question
In severe acute cardiogenic pulmonary edema, does early noninvasive ventilation improve short-term mortality or intubation-related outcomes compared with standard oxygen therapy?
What the trial found
Early NIV improves symptoms and gas-exchange physiology rapidly in acute cardiogenic pulmonary edema, but 3CPO did not establish a mortality or intubation benefit.
Clinical interpretation
Supports symptom/physiology benefits of early NIV while preventing overstatement of 3CPO as a mortality or large intubation-reduction trial.
