Frequently
asked questions
How long did it take you to build the first prototype?
One of the questions we get asked most often is this one.
For the definition of an IBD prototype it took 5 weeks to build.
What do I do if Biorespira returns error E1?
Turn off and restart.
If the problem persists, contact technical support.
What do I do if Biorespira returns error E2?
- Check that the oxygen in the O2 cylinder has not finished;
- Check that the cylinder/wall outlet O2 valve is open;
- Check that the oxygen tube is not bent;
- Check the connection of the oxygen cylinder and tube;
- Check that the oxygen system which Biorespira is connected to delivers at least 0.7 bar;
- Check that the Flow and % of Oxygen are set correctly. 100% Oxygen can be set with a maximum of 50 litres per minute. Check the Oxygen and Flow setting modes in the manual;
- Press the RESET and then START buttons to return to therapy.
If the problem persists, contact technical support.
What do I do if Biorespira returns error E3?
Was the error given within the first 5 minutes of therapy?
NO: contact technical support on the freephone number indicated in the footer of the website.
YES:
- Check that the oxygen in the O2 cylinder has not finished;
- Check that the cylinder/wall outlet O2 valve is open;
- Check that the oxygen tube is not bent;
- Check the connection of the oxygen cylinder and tube;
- Check that the oxygen system which Biorespira is connected to delivers at least 0.7 bar;
- Check that the Flow and % of Oxygen are set correctly. 100% Oxygen can be set with a maximum of 50 litres per minute. Check the Oxygen and Flow setting modes in the manual;
- Press the RESET and then START buttons to return to therapy.

What do I do if Biorespira returns error E4?
Check that the air inlet on the inlet filter side is not blocked.
If the problem persists, contact technical support.
What do I do if Biorespira returns error E5?
- Start therapy with the lowest PEEP and then increase it to the tolerated value;
- Check that the Biorespira air outlet tube is not bent;
- Check that the Biorespira air outlet tube is not blocked;
- Press the RESET and then START buttons to return to therapy.
If the problem persists, contact technical support.

- Do not disconnect the helmet tube and/or PEEP tube while treatment is in progress;
- Check that the helmet/other interfaces are of the correct size;
- Make sure the patient is cooperative and there is no change in the state of consciousness;

Turn off and restart.
If the problem persists, contact technical support.
What do I do if Biorespira returns error E9?
- Check the electrical connection of the device;

- Verify that there has not been a temporary power outage;
- Resume the therapy and set the parameters again.
If the problem persists, contact technical support.
What do I do if Biorespira returns error E10?
The battery may have discharged excessively. Keep the device on in alarm mode for 30 minutes to allow the battery to recharge, and try again.
If the problem persists, contact technical support.
What do I do if Biorespira returns error E11?
Turn off and restart.
If the problem persists, contact technical support.
What do I do if Biorespira returns error E12?
- Make sure that neither the outlet filter nor the respiratory circuit are connected and that the dust filter is inserted correctly;
- Make sure that the inlet filter is in place and inserted correctly;
- Make sure that the Biorespira air inlet is not blocked;
- Make sure that the Biorespira air outlet is not blocked;
- Turn off and restart.
If the problem persists, contact technical support.
What do I do if Biorespira returns error E13?
- Turn off the device and make sure that the PEEP pressure tube is not connected at start-up.
- Turn off and restart.
If the problem persists, contact technical support.
What do I do if I cannot turn on Biorespira?
- Check that the power supply socket is connected properly to the wall;
- Connect the power supply to another socket/check that the socket supplies power by connecting another electronic device;
- Check that the power supply on Biorespira is connected correctly;
- Replace the power supply;
- Turn off and restart.
PLEASE NOTE: The green light on the power supply must be ON to indicate proper operation.
If the problem persists, contact technical support.
What do I do if Biorespira starts up but freezes on the logo screen?
Turn off and restart.
If the problem persists, contact technical support.
What do I do if Biorespira starts up correctly but the screen does not hear the commands?
- Clean the screen and try again;
- Turn off and restart.
If the problem persists, contact technical support.
