Objectives: 1) To evaluate the prognostic roles of quantitative CT and pulmonary function tests and 2) to assess the association of dynamic strain and ventilation heterogeneity during unassisted spontaneous breathing with 90-day survival in patients with paraquat poisoning. Design: Prospective study. Setting: A university hospital ICU. Patients: One-hundred spontaneously breathing patients with paraquat poisoning without mechanical ventilation. Interventions: A standardized treatment protocol. Measurements and Main Results: Blood samples were collected to measure the plasma paraquat concentration upon arrival. CT scans at suspended inspiration and pulmonary function tests were performed at day 5. The weight of the poorly aerated lung compartment as a percentage of total lung weight (%Wpoor) was exponentially transformed, generating a new variable, Exp(%Wpoor/15). The functional residual capacity that was determined by helium dilution was used to calculate the dynamic strain (tidal volume/functional residual capacity by helium dilution method). Respiratory system reactance at 5 Hz was used as a marker of ventilation heterogeneity. Exp(%Wpoor/15) (adjusted hazard ratio, 2.58; 95% CI, 2.021–3.296; p
