Q: The plateau pressure (Pplat) on the ventilator should be measured with a pause at? (select one)
Pplat is the reflection of static compliance of the whole respiratory system taking into account of lung parenchyma, chest wall, as well as an abdominal effect on respiratory mechanics, so the Pplat is measured while there is no airflow.
Knowing that Pplat should be measured at pause and at end-inspiration.
