Abstract
The ventilator mode refers to the way the ventilator interacts with the patient. Assist control (AC) is one of the most commonly used modes of ventilation, set to either target a desired pressure or volume. Pressure support ventilation is a partially supported, or spontaneous, pressure-controlled mode of ventilation with no set respiratory rate or tidal volume. The peak inspiratory pressure (PIP) represents pressures in the entire airway system and is a measure of both the resistance and compliance. The plateau pressure (Pplat), which is measured during an inspiratory hold, is the reflection of the pressure delivered to the alveoli and the compliance of the system. When air is trapped in the alveoli at the end of exhalation, it exerts a pressure above and beyond the set PEEP. This pressure can actually be quantified on the ventilator by pressing the expiratory pause button and is known as AutoPEEP or intrinsic PEEP (iPEEP).
