This 1-hour live online course explores the clinical value of Ventilator Loops in mechanical ventilation. Participants will learn how pressure–volume and flow–volume loops reveal important information about lung mechanics, patient effort, and ventilator performance. Through guided interpretation and real-world examples, learners will develop the ability to recognize abnormal loop patterns and apply this knowledge to optimize patient–ventilator synchrony. As the fourth class in the Riding the Wave series, this session builds on scalar graphs and deepens the learner’s ability to use ventilator graphics to improve patient care.
