I:E Ratio Made Easy

Respiratory HQ

IE ratio is explained using an analogy of taking a trip. The respiratory rate determines the trip time, the tidal volume is the length of the train, and the flow is the speed of driving. Increasing tidal volume increases inspiratory time and decreases expiratory time. Increasing flow decreases inspiratory time and increases expiratory time.
