PC-CMV Relationship of Delivered Minute Ventilation & Set Frequency



Mathematical Review of Pressure Preset Ventilation

Minute ventilation as a function of set frequency with no airflow obstruction. Minute ventilation rises toward a final plateau determined by I-time & resistance. However, compliance determines the rate of the rise of the curves.

Relationship of frequency to tidal volume during PC-CMV




Review of Mathematical Principles of Pressure Preset Mechanical Ventilation

This video demonstrates the relationship between set frequency to delivered tidal volume during Pressure control ventilation. Reductions in compliance or increases in frequency decrease delivered VT.
