Rise Time adjustment
In S, ST and T modes, Rise Time sets the time taken for the device to reach IPAP. As rise time increases, the longer the device takes to increase pressure from EPAP to IPAP. Patients with high ventilatory requirements often prefer shorter rise times, while patients who are slow breathers often prefer longer rise times.
Note
A prolonged rise time inhibits fast pressurization; therefore, rise time should not be set longer than Ti Min or the patient's normal inspiratory time.
