Tóm tắt

   This clinical case report detailed a 60-year-old obese female (BMI 44 kg/m²) with severe ARDS. The patient underwent mechanical ventilation with PEEP 16 cmH₂O, but due to obesity and high PEEP, CT imaging was not feasible. Bedside Electrical Impedance Tomography (EIT) was employed for lung function monitoring.
   Continuous EIT assessed regional lung ventilation, analyzing impedance changes to evaluate lung homogeneity and regional ventilation delay. Initial findings revealed significant inhomogeneity and regional ventilation delay. However, with EIT monitoring and adjustments to ventilator settings, coupled with physical therapy, the patient's regional ventilation gradually improved. After 7 days, the patient was successfully weaned off mechanical ventilation.
   This case demonstrated the utility of bedside EIT in monitoring lung function in severe ARDS patients, especially those with obesity. Real-time, non-invasive assessment of regional lung ventilation facilitated optimized ventilator settings and improved outcomes.
