Options and Accessories

1.Touch either the I-Trigger or E-Trigger button in the Settings screen (Figure 13-70). The I- Trigger or E-Trigger window will appear as shown in Figure 13-73 or Figure 13-74.

2.Change the I-Trigger setting to Pressure or Flow, or change the E- Trigger setting to %Peak Flow. (When you change the I-Trigger setting to Pressure or Flow, the E- Trigger reverts to the most recently selected %Peak Flow value. Similarly, when you change the E-Trigger setting to %Peak Flow, the I-Trigger reverts to the most recently selected Pressure or Flow value.)

3.Touch the Accept button in the I-Trigger or E-Trigger window. The Settings screen will display the current I-Trigger and E-Trigger values as shown in Figure 13-70.

In order to determine triggering and cycling sensitivity thresholds for each breath, Auto-Trak applies multiple algorithms derived from flow, volume and pressure measurements throughout the breathing cycle.

Triggering

Auto-Trak monitors changes in pressure and flow patterns throughout exhalation, applies compensation for circuit leaks, and triggers an inspiration when the criterion for one of the triggering algorithms has been met. As a backup, Auto-Trak uses pressure triggering at a fixed level of 3 cm H2O.

Cycling

Auto-Trak automatically cycles breathing based on the pressure and flow patterns at the end of inspiration and beginning of expiration. The threshold used to cycle each breath changes with the patients breathing pattern and lung dynamics.

Patient leaks at the mask interface are a critical factor and are significant in determining triggering and cycling thresholds. With noninvasive ventilation, failure to compensate for these leaks can impact the patients work of breathing.

Patient leak is the average leak rate during a breath and is estimated as the delivered volume minus exhaled volume divided by the total breath time. This average estimated leak value is displayed in LPM as Pt Leak in the Patient Data section of the Settings screen. Pt Leak is updated with each breath.

Bias flow through the patient circuit is adjusted according to the estimated leak and is quantified as follows:
