Figure 2From: 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 mean arterial pressure. (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 Group 1 vs. Group 3.Back to article page
