Abstract

The study aimed to assess changes in circulatory, respiratory and lung mechanics indices of PSV mode compared to SIMV mode in patients postoperative mechanical ventilator discontinuation. 70 patients who are removed 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 circulatory, respiratory and lung mechanics indices (VT, MV, PIP) from controlled ventilation to PSV and SIMV mode were recorded at 30 minutes, 60 minutes and 90 minutes. In the SIMV group, heart rate, blood pressure, and respiratory rate increased statistically significantly compared to the PSV group when switching from A/C mode to PSV or SIMV mode and gradually decreasing the support pressure level. The PIP index was also higher than that of the PSV group. Our study shows that the SIMV mode may required more effort from patients  than the PSV mode when mechanical ventilator is discontinued after surgery.
