Abstract

The purpose of this study is to compare changes in indirect calorimetry indices of PSV mode compared to SIMV mode in patients with postoperative mechanical ventilator discontinuation. 70 patients weaned from mechanical ventilation after surgery were divided into 2 groups: 35 patients with PSV mode and 35 patients with SIMV mode at the Department of Anesthesia Critical Care and Pain Management, Hanoi Medical University Hospital from December 2019 to July 2020. Changes in indirect calorimetry indices (VO2, VCO2, REE) from controlled ventilation to PSV and SIMV mode were recorded at 30 minutes, 60 minutes and 90 minutes. In the SIMV group, VO2, REE increased statistically significantly compared to the PSV group when switching from A/C mode to PSV or SIMV mode. Our study shows that the SIMV patients may require more respiratory effort than the PSV patients when mechanical ventilator was discontinued after surgery.
