Running the Pre-Use Test
The V*Home Pre-Use Test calculates the resistance and leak of the Ventec One-Circuit. Based on these calculations,
V*Home veries the integrity of the Ventec One-Circuit, and also improves the accuracy of therapy delivered during
ventilation.
To ensure therapy is delivered accurately, you must perform a Pre-Use Test whenever prompted, the patient circuit is
changed, or the device is powered on.
WARNING: Ventilation therapy is paused during the Pre-Use Test. If Ventilation therapy is critical to patient care,
provide backup ventilation for the duration of the test. To ensure patient safety, always verify Ventilation therapy is
resumed when the Pre-Use Test is complete.
NOTE: Though accuracy may be reduced, V*Home may still be used to provide ventilation therapy when the Pre‑Use
Test fails. If time constraints make running the test inadvisable, press the EXIT button to immediately initiate Ventilation
therapy.
NOTE: To calculate resistance correctly, the Pre‑Use Test must be performed without an HME connected to the Ventec
One-Circuit.
Some control changes cause V*Home to prompt you to run a Pre-Use Test. You may also press
the Menu tab and then the PRE-USE TEST button to begin a Pre-Use Test at any time.
To run a Pre-Use Test, carefully follow the on-screen instructions. When instructed, use a clean,
gloved hand to obstruct the circuit completely, as follows:
• If you are using a Passive, or Valveless Ventec One-Circuit, disconnect the patient interface
and block the circuit at its end.
• If you are using a Mouthpiece patient circuit, leave the mouthpiece connected, and block the open end.
If the test completes successfully, reconnect the Ventec One-Circuit to the patient and resume Ventilation therapy. If the
test fails, inspect the Ventec One-Circuit conguration for leaks or improper setup. Resolve any issues with the Ventec
One-Circuit, and then press RESTART to run the Pre-Use Test again.
