WebJan 28, 2024 · VE = Respiratory Rate x Tidal Volume. Alveolar Minute Ventilation (VA) VA = Respiratory Rate x (Tidal Volume – Deadspace) Airway Resistance (Raw) Raw = (PIP – Plateau pressure) / Flow. Mean Airway Pressure (Paw) Paw = ( (Inspiratory Time x Frequency) / 60) x (PIP – PEEP) + PEEP. Work of Breathing (WOB) WOB = Change in … WebDec 14, 2024 · Another way to look at this is to calculate the dead space fraction (V D /V T) for each breath. In the first case, it is 150/700 = 0.21. After changing the settings, it would be 150/300 = 0.5. Hence, for the same minute ventilation, a rapid shallow breathing pattern increases anatomical dead space fraction.
