Ventilator can control only one variable at a time. Equation of Motion: Pvent = v̇xR + VxE + PEEP where Pvent is peak pressure, E is Elastance, V is volume, R is resistance and v̇ is flow. Elastance is also the inverse of compliance. Memorize this …
Webb12 jan. 2012 · A decelerating pattern offers the highest level of flow at the start of a breath, when patient flow demand is often greatest. 1 This flow pattern, when used in a pressure-regulated mode of ventilation, may lead to improved patient/ventilator synchrony and provide benefits to those patients who demand high inspiratory flow rates.
