This 1-hour live online course introduces healthcare providers to the essential skill of interpreting scalar graphs in mechanical ventilation. Participants will learn how pressure, flow, and volume scalars reflect patient–ventilator interactions, identify normal versus abnormal waveforms, and recognize how changes in scalars guide clinical decision-making. Designed as the first step in the Riding the Wave series, this interactive session builds a strong foundation for understanding ventilator graphics and applying them to improve patient care.
