Lucas, it's not uncommon to see questions like "what is the best ventilatory mode for a given situation?". Although this seem an evasive answer, I'd rather to say that there is no ideal ventilatory mode for a given situation. Explanation: Theoretically, for a patient with pulmonary fibrosis, a controlled pressure mode would be ideal, however, this can result in ventilation compromise due to a low tidal volume, so maybe this patient would be better with a volume controlled mode. The best mode is the one that best fits your patient, respecting the limits of peak pressure (typically 40 cm H2O), SpO2, Tidal Volume (no more than 8 ml / kg (ideal weight, not the actual)), etc ... It is with general anesthesia correct? I would first try an adaptation of PRVC mode (if your mechanical ventilator have it), then try VCV or PCV. Hope this helps

As one of my more experienced colleague once said '' ventilators are now build and programed to such a level to avoid trauma and to provide adequate ventilation condition so any mode you are most familiar with can be safely used for almost any type of general anaesthesia''. Of course, we must take into account the conditions of the patient and physiological impact on the patient by the procedure performed.

I usually use PCV in laparoscopic surgery, changing the parameters of the ventilator parameters to optimise the ventilatory status. But there were situations when I had to switch to VCV because I wasn't getting anywhere with PCV. So the best type of ventilatory mode is the one you are most comfortable and the one that suits your patient best as mentioned in the previous answer

PRVC or VCV can be used. In most of the ventilators in anesthesia machine, PRVC mode is not available so VCV is the most common option. RR (respiratory rate) should be adjusted (increased) accordingly to keep the ETCO2 within normal range. In Trendelenburg position, head is lowered and abdominal contents pushes the diaphragm upward so small tidal volume is preferred (6-8 ml/ Kg of ideal body wt.).
