Note The airway module sampling flow is paused during the checkout
when an airway module is installed within the system. If an airway
module is installed on an external monitor outside of the system,
disconnect the gas sampling line from the patient circuit and close
the sample port before performing the checkout.
The Ventilator Leak test checks the ventilator, bellows, gas
supplies, and breathing circuit for gas leaks in the mechanical
ventilation mode.
To run this test, follow the on-screen instructions. When the test
passes, the next test starts.
The Vaporizer Leak test checks for leaks in the vaporizers. The
patient circuit compliance is also measured during this test.
To run this test, follow the on-screen instructions. When the test
passes, the next test starts.
The Gas Controls test checks the flow control valves and gas flows.
To run this test, follow the on-screen instructions. When the test
passes, the next test starts.
The Link-25 system does not replace an O2 monitor.
Sufficient O2 in the fresh gas may not prevent hypoxic
mixtures in the breathing circuit.
• Nitrous oxide (N2O), if available, flows through the
system during this test. Use a safe and approved
procedure to collect and remove the N2O.
• Incorrect gas mixtures can cause patient injury. If the
Link-25 system does not supply O2 and N2O in the
correct proportions, do not use the system.
The Circuit Leak test checks the Bag/Vent switch, proper gas supply
pressures, airway pressure measurement transducer, APL valve,
and manual circuit leak.
