This course breaks down how to think about the ventilator as an anesthetic tool rather than an ICU life-support device. You’ll compare VCV, PCV, SIMV, PSVPro, and ACV in the OR context, learn when each mode shines (and when it can hurt your patient), and see how positioning, pneumoperitoneum, and one-lung ventilation change your approach. Practical, case-focused guidance on tidal volume selection, PEEP, recruitment maneuvers, and pressure limits will help you apply true lung-protective strategies intraoperatively—reducing postoperative pulmonary complications while keeping gas exchange rock solid throughout the case.
