A ventilator is a machine that delivers a flow of gas for a certain amount of time by increasing proximal airway pressure, which culminates in a delivered tidal volume. Because of the imprecise, inconsistent, and outdated terminology used to describe modern ventilators, many clinicians often misunderstand exactly how a ventilator functions. Understanding the exact instructions that a ventilator follows to deliver a breath for the various modes of ventilation is crucial for optimal ventilator management.
