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

Figure 5 Boxplot of arterial partial pressure of oxygen/ fraction of inspired oxygen ratio 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 the supine and right lateral decubitus position after one-lung flooding, PaO₂/FiO₂ ratio during superimposed high-frequency jet ventilation was significantly lower than during PCV. 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; PaO₂/FiO₂: Arterial partial pressure of oxygen/fraction of inspired oxygen (Horowitz index).
