During the operation, to allow the surgeon to work more precisely, only one lung will receive air from the respirator. To improve visibility during surgery, a small amount of carbon dioxide is introduced into the space between the lung and the chest wall, a procedure called capnothorax. The aim of the research is to find the best way to set the patient's ventilation during the operation, ensuring adequate oxygenation and minimizing the risks to the lung. To do this, we will use a method of measuring the pressure inside the esophagus, which will allow us to better understand the status of the lungs and adjust ventilation accordingly. Esophageal pressure is an indirect measure of the pressure within the lung. By measuring this pressure, we can get important information about the status of the lungs and their ability to expand and contract. By measuring esophageal pressure, researchers will be able to set ventilation more precisely, optimizing the amount of air that is supplied to the lungs and the pressure inside the lungs themselves.
