Comparing Mechanical Power in Different Inspiratory Times

Başakşehir Çam & Sakura City Hospital30 enrolled

Overview

We aimed to compare mechanical power and energy values using geometric methods at varying inspiratory rise times.

In this study, the researchers aim to compare the mechanical power and energy values calculated using the geometric method in Volume-Controlled Ventilation (VCV) and Pressure-Controlled Ventilation (PCV) modes at different inspiratory rise times.

Interventions

Mechanical ventilator adjustment for PCVPROCEDURE

In pressure control ventilation (PCV) mode, patients will be ventilated for 5 minutes at a Tslope of 5% and another 5 minutes at 15% for both 1:1 and 1:2 I:E ratios. After each adjustment, screenshots of the mechanical ventilator (P-V loop screenshots) will be obtained . A total of 20 P-V loop screenshots will be captured over a 20-minute period (10 for the 1:2 ratio and 10 for the 1:1 ratio), which will be stored in the ventilators memory. The stored data will then be transferred from the ventilators memory to a computer via a flash drive.
