Vetland EX3000, Operator'S Manual

Page: 41 / 88

Operation 5-3
Using the Oxygen Flush Button
If the patient should require high concentrations of oxygen instantaneously, the operator can activate the
oxygen flush button. Once activated, the flow meter and anesthetic vaporizer are bypassed and oxygen is
administered to the patient without anesthetics. As soon as the oxygen flush button is released, the preset
anesthesia mixture will again be administered.
Note: The oxygen flush is always available to the patient as long as there is 50 psi of oxygen supply
pressure. Should the system lose power or become unable to provide fresh gas mixtures, the
O
2
flush can be utilized to oxygenate the patient. Use caution to avoid over pressurizing the
anesthesia system/patient.
Post-anesthesia Procedure
Once the anesthesia procedure is completed, perform the following steps in order:
1. Touch the STOP button on the system touch screen for two seconds to stop all flows and halt the
case clock. The case clock automatically resets with the start of the next case (when oxygen flow
starts).
2. Press the oxygen flush button for two to three seconds and squeeze the breathing bag to purge the
system of anesthetic gases and carbon dioxide.
3. Open the pop-off valve by turning it counter-clockwise. This will assure that, while breathing
spontaneously, the next patient can exhale freely and with no resistance.
4. Check the absorbent in the CO
2
absorber canister. If the color has turned blue or after
approximately 8 to 10 hours of surgery, change the absorbent as described in Section 4 – System
Setup . The blue dyes in the absorbent are activated when CO
2
can no longer be absorbed.
Note: Expired absorbent can change back to white overnight, unless you are utilizing Litholyme
TM
absorbent available from Vetland which retains its color change indefinitely.
TIP To make sure the CO
2
absorbent is fresh, change the absorbent each time anesthetic agent
is added.
