Summary

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

Detailed description

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.

Conditions

• Ventilator-Induced Lung Injury
• Acute Respiratory Distress Syndrome

Interventions

Type	Name	Description
PROCEDURE	Mechanical ventilator adjustment for PCV	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.
