This course gives anesthesia providers a practical, ventilator-focused approach to understanding and managing dead space in the OR. You’ll clarify the difference between anatomical and physiological dead space, learn how to use volumetric capnography and VD/VT to fine-tune ventilation, and explore how inhalational agents like isoflurane alter dead space through bronchodilation—so you can prevent CO₂ retention and optimize gas exchange, especially in high-risk and mechanically ventilated patients.
