Table 4.1: Ti Max Setting Guide - ResMed Elisee 150 Clinical Manual

Maximum inspiratory time
The maximum time for which the device will maintain inspiratory pressure before cycling to
expiration. It gives the patient a window of inspiratory time in which to spontaneously cycle into
the expiratory phase. Ti Max is available in spontaneous mode only (see "Spontaneous ventilation
(PS.SV (PS) and PS.VT)" on page 56).
The following table enables you to select the Ti Max value which best fits the patient's
spontaneous respiratory rate.
