- Values are presented as pooled means of studies weighted by number of patients.
- aOR per 0.01 unit change. FiO2 = fraction of inspired oxygen; MAP, mean airway pressure (cmH2O); OI, oxygenation index; OR, odds ratio; PaCO2, pressure of arterial carbon dioxide (mmHg); PAF, pressure of arterial oxygen (mmHg)/fraction of inspired oxygen; PEEP, peak end-expiratory pressure (cmH2O); PIP, peak inspiratory pressure (cmH2O); TimeCV, time on conventional mechanical ventilation (CV) prior to high frequency oscillatory ventilation (days).
