Comparing Mechanical Power in Different Inspiratory Times

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.
