Establishment of a Predictive System for Perioperative Risk Assessment and Electronic Flowcharting Response Strategies in Thoracic Surgery

ARDS definition was based on the new global definition of ARDS10. Briefly, intubated ARDS was defined as an oxygenation index of less than 300 under a positive end-expiratory pressure (PEEP) of at least 5 cmH2O, and non-intubated ARDS was defined as patients receiving high-flow nasal oxygen (HFNO) ≥ 30 L/min or noninvasive ventilation/continuous positive airway pressure (NIV/CPAP) with a PEEP of at least 5 cmH2O and meeting PaO2:FiO2 ≤ 300 mm Hg or SpO2:FiO2 ≤ 315 (if SpO2 ≤ 97%).

refers to the number or percentage of patients who die while being treated in a hospital.

Length of hospital stay(days): refers to the total number of days a patient spends in the hospital from the time of admission to the time of discharge.

Length of ICU stay(hours): refers to the total duration of time a patient spends in the Intensive Care Unit (ICU) during a single admission.

Length of postoperative stay(days): refers to the duration of time a patient remains in the hospital or medical facility after undergoing surgery.

Duration of mechanical ventilation(hours): refers to the length of time a patient requires assistance from a mechanical ventilator to maintain adequate breathing.

Duration of HFNC(hours): refers to the length of time that a patient is treated with High-Flow Nasal Cannula (HFNC) therapy.
