CAUTION
Do not overturn the Patient Circuit Calibration as this may cause damage to the device. When it is nearing its
adjustment limit, it will reach a mechanical stop.
CAUTION
8. Perform the Ventilator Performance Check “Off Patient Only” section. (These instructions
are also located on a label on the top of the Control Package).
a. Insert stopper in Patient Circuit “Y” and turn on both gas sources.
b. Set BlAS FLOW for 30 LPM.
c. Set Max Pa Alarm to 35 cmH2O.
d. Rotate Mean pressure “ADJUST” knob to 12 o’clock position.
e. Pressurize system by pressing and holding RESET, and ADJUST for a mean Pressure
of 29-31 cmH2O.
f. Set FREQUENCY to 6, % I-Time to 33, and press START/STOP to start the oscillator.
g. Set POWER to 6.0.
h. When a stable ∆P reading is obtained, verify that the ∆P and Pa readings are within
the range specified for your corresponding altitude (see Figure 7.1).
9. Depress the START/STOP button to stop the oscillator.
10. With Mean Pressure Adjust and/or Bias Flow adjustment, achieve a mean airway
pressure within 2 cmH2O of the desired level. Ensure that the Bias Flow is sufficient (see
Chapter 9, Clinical Guidelines).
11. Verify the function of the thumb-wheel switches for “Set Max Pa” and “Set Min Pa”
alarms by setting the Max thumb wheel just below the established Mean pressure, and
by setting the Min thumb wheel just above the established Mean pressure.
12. Set these thumb-wheel alarm switches to their desired settings. This is generally 2–5
cmH20 above (Max thumb-wheel) and below (Min thumb wheel) the established Mean
pressure.
13. With fingers and thumb(s), squeeze closed the 1/8" clear Pressure Sense tubing on the
patient circuit to verify operation of the “Pa > 60 cmH2O” alarm.
14. Depress the RESET button until the “Pa < 5 cmH2O” LED is extinguished to
reestablish the mean airway pressure.
15. Again, squeeze the pressure sense tubing on the patient circuit and observe the
pressure at which the Mean Pressure display limits.
16. Position the ventilator for connection to the patient. Loosen the Position Lock control and
adjust the angle of the Control Package for the best view and access relative to the
patient. Retighten the Position Lock.
17. Set the desired % oxygen, Mean Pressure, and ∆P for the patient. ∆P will affect the Pa
depending on ratio of Flow Rate/Pa. The lower the ratio, the stronger the effect.
Fractional concentration of inspired oxygen should be verified with an oxygen monitor. Administration of excessive
oxygen to a patient may be harmful. It is imperative that the prescribed gas mixture is delivered by the blending
system.
