“…To test our hypothesis, we performed an experimental work to measure actual TV delivered to the patient using 3 different ventilation modes: PRVCV, PCV, and VCV. lung simulator, enabling control of the simulated airway resistance using a valvular system [14]. An Ohmeda 5410 volume monitor (BOC Health Care, Englewood CO) was connected to the entrance of the lung simulator to measure the volume of gas that actually entered the simulator (ie, the volume that would actually reach the endotracheal tube).…”
