FIGURE 3-9: SELECTION OF PERTURBATIONS TO BE CALIBRATED
Closed Preparation
Be sure to block the end of the cannula tightly, and then click Next . If the cannula is
not completely blocked, the calibration may need to be repeated.
Closed Calibration
While the cannula is blocked, the flexiVent executes each perturbation that you
selected. Do not unblock the cannula until all perturbations are complete.
Open Preparation
Unblock the cannula and click Next .
Open Calibration
While the cannula is open to atmosphere, the flexiVent executes each perturbation
again. Do not reposition or remove the cannula until all perturbations are complete.
Calibration Results
The tube calibration results contain important information that can help you
validate your setup. Verify that the Rl (leak resistance) value associated with your
Deep Inflation perturbation is within acceptable range using the results as shown
in Figure 3-10 and the calibration guide in Table 3-1. In addition, examine the Rt
(tube resistance) value associated with the SnapShot perturbation. This value
reflects the resistance of your tracheal cannula or intubation tube and as such, it
should be lower than a typical baseline resistance for the species you are studying.
