This book discusses the interpretation mechanical ventilator waveforms. Each page shows a screenshot from a real patient and explains one or two messages. It starts with basic information about the waveforms and goes on to address passive and spontaneous ventilation, non-invasive ventilation and specific measurements such as pressure-volume curves and esophageal pressure. Step by step, readers learn about advanced monitoring of patient-ventilator synchronisation. This unique teaching approach has been adapted to this topic.
