Which of the following statements about ARDS in adults is NOT correct
Responda
Bilateral opacities consistent with pulmonary edema on chest radiography Or computed tomography scan that are not fully explained by pleural effusions, lobar/lung collapse, pulmonary nodules or heart failure are required for the diagnosis
Several conditions can lead to the development of ARDS, including aspiration of gastric contents, pneumonia, sepsis (most common cause), trauma, transfusion of blood products (particularly plasma-rich products), pancreatitis, fat emboli, and drowning
Most patients with ARDS require intubation and mechanical ventilation with low tidal volumes (6 mL/kg predicted weight) and targeted plateau pressures of equal to or less than 30 cm H20
Moderate to severe impairment of oxygenation is defined by the ratio of arterial oxygen tension to fraction of inspired oxygen (PaO2/FiO2). In Severe ARDS PaO2/FiO2 is between 200 and 300 mmHg on PEEP >5 cm H2O
