Effects of unilateral superimposed high-frequency jet ventilation on porcine hemodynamics and gas exchange during one-lung flooding

Figure 6 Boxplot of shunt fraction for controls, pressure-controlled ventilation and superimposed high-frequency jet ventilation at baseline, one-lung flooding/one-lung ventilation in different animal positions and after one-lung flooding. In all positions after one-lung flooding, Qs/Qt during superimposed high-frequency jet ventilation was significantly higher than during pressure-controlled ventilation. SHFJV: Superimposed high-frequency jet ventilation; PCV: Pressure-controlled ventilation; OLF: One-lung flooding; OLV: One-lung ventilation; TLV: Two-lung ventilation; LLP: Left lateral position; SP: Supine position; RLP: Right lateral position; Qs/Qt: Right-to-left shunt fraction.
