Many patients admitted to the postoperative ICU require ventilator ventilation. Still, inappropriate PEEP (Positive End-Expiratory Pressure) settings are known to cause dorsal atelectasis and ventral hyperinflation, resulting in inhomogeneous ventilation distribution. EIT (Electrical Impedance Tomography) is a bedside device that noninvasively monitors ventilation distribution over time without x-ray exposure. Our studies using EIT have shown that patients at high risk for postoperative pulmonary complications exhibit phenotype 1 (ventral dominance), phenotype 2 (uniform ventilation distribution), and phenotype 3 (dorsal dominance) ventilation patterns. Furthermore, in the PEEP setting based on clinical judgment, approximately 60% of patients had heterogeneous ventilation distribution (phenotype 1, phenotype 3), and there was an association between heterogeneous ventilation distribution and increased postoperative pulmonary complications and prolonged ventilation. Therefore, ventilator management with a more uniform distribution ventilation may improve prognosis compared to conventional PEEP/FiO2 table. This study aimed to determine whether EIT-based PEEP settings are effective in achieving uniform ventilation distribution in patients at high risk for postoperative pulmonary complications who present with heterogeneous ventilation distribution.
