Traditional oxygenation indices require arterial blood gas analysis and do not fully reflect the mechanical stress applied to the lungs.\n\nThis prospective observational study aims to evaluate the correlation between oxygenation indices and oxygen saturation indices during one-lung ventilation in adult patients undergoing elective thoracic surgery. Modified indices incorporating driving pressure and mechanical power will also be assessed.\n\nNo intervention beyond standard clinical care will be applied.
