Figure 1From: Continuous negative extrathoracic pressure combined with high-frequency oscillation improves oxygenation with less impact on blood pressure than high-frequency oscillation alone in a rabbit model of surfactant depletion Changes in oxygen index (OI) in experiments. (Diamond) Group 1: CNEP (-10 cmH2O) with low-MAP (10 cmH2O) HFO. (Circle) Group 2: Low-MAP (10 cmH2O) HFO. (Square) Group 3: High-MAP (15 cmH2O) HFO. *p < 0.05 Groups 1, 3 vs. Group 2.Back to article page
