Mechanical Power During Different Ventilation Modes in Laparoscopic Surgery

Sponsor: Dr Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital

Summary

This study investigates how different breathing machine (ventilator) settings affect the energy delivered to the lungs during surgery. Mechanical power is a measure of this energy, and high levels can sometimes lead to lung irritation. In clinical practice, a mode called Pressure-Regulated Volume Control (PRVC) is often used because it lowers the "peak" pressure in the airways, which is generally thought to be safer. However, doctors have noticed that even though the peak pressure goes down in PRVC mode, the total mechanical power displayed on the monitor might actually increase compared to the standard Volume-Controlled Ventilation (VCV) mode. In this study, patients undergoing gallbladder surgery will be monitored using both ventilation modes in a random order. The researchers will compare the machine-calculated mechanical power for both modes to see if the perceived benefit of lower peak pressure in PRVC actually results in lower overall energy transfer to the lungs.
