The expiratory phase of airway pressure release ventilation (APRV) may provide physiologic information about lung volume based on the expiratory flow-time slope, angle, and time to approach a no-flow state (expiratory time [T_E]). We hypothesized that expiratory flow would correlate with estimated lung volume (ELV) as measured using a modified nitrogen washout/washin technique in a large-animal lung injury model.</p><p><strong>Methods: </strong>Eight pigs (35.2 ± 1.0 kg) were mechanically ventilated using an Engström Carescape R860 on the APRV mode. All settings were held constant except the expiratory duration, which was adjusted based on the expiratory flow curve. Abdominal pressure was increased to 15 mm Hg in normal and injured lungs to replicate a combination of pulmonary and extrapulmonary lung injury. ELV was estimated using the Carescape FRC INview tool. The expiratory flow-time slope and T_E were measured from the expiratory flow profile.</p><p><strong>Results: </strong>Lung elastance increased with induced lung injury from 29.3 ± 7.3 cm H₂O/L to 39.9 ± 15.1cm H₂O/L, and chest wall elastance increased with increasing intra-abdominal pressures (IAPs) from 15.3 ± 4.1 cm H₂O/L to 25.7 ± 10.0 cm H₂O/L in the normal lung and 15.8 ± 6.0 cm H₂O/L to 33.0 ± 6.2 cm H₂O/L in the injured lung (<i>P</i> = .39). ELV decreased from 1.90 ± 0.83 L in the injured lung to 0.67 ± 0.10 L by increasing IAP to 15 mm Hg. This had a significant correlation with a T_E decrease from 2.3 ± 0.8 s to 1.0 ± 0.1 s in the injured group with increasing insufflation pressures (ρ = 0.95) and with the expiratory flow-time slope, which increased from 0.29 ± 0.06 L/s² to 0.63 ± 0.05 L/s² (ρ = 0.78).</p><p><strong>Conclusions: </strong>Changes in ELV over time, and the T_E and flow-time slope, could be used to demonstrate evolving lung injury during APRV.
