FIGURE 3-6: RESULTS OF CALIBRATING THE CYLINDER PRESSURE CHANNEL
If your values are not within the expected range, the pressure applied with the
manometer may not have matched the value entered in the calibration dialogue. Note
that if you are using a U-shaped manometer, the amount of pressure applied is equal to
double the change in height on one of the columns. If you used a SCIREQ manometer,
the amount of pressure applied is equal to the level of fluid in the single column. Please
refer to the instructions provided with the SCIREQ manometer for further details. If
you have questions concerning the use of the SCIREQ manometer, contact Technical
Support.
Calibrate the airway opening pressure channel. Again, most templates require a two
point calibration in which the first point is 0 mmH
2
O (open to atmosphere) and the
second point is approximately 300 mmH
2
O (applied using a manometer) to cover the
range of expected pressures. Be sure to enter the actual pressure applied in Step 8
(see Figure
3-7).
