About this Tool


This tool will help you calculate the respiratory rate (ƒ) needed to achieve the prescribed inspiratory time [T-high (TH)] and release time [T-low (TL)] values for Puritan Bennett™ ventilators.

This calculator is not a substitute for the exercise of professional judgment and is not intended to replace the Operator’s Manual, which should always be available while using the ventilator.
