MIP/MEP test
The MIP/MEP test measures the maximum inspiratory/expiratory pressure of the
patient. He/She breathes normally until the start of the test, perform a maximal
expiration/inspiration and then inspires/expires with the maximum force against a valve
which does not allow the air flow.
The measured parameters are:
MIP
Maximum inspiratory pressure
MEP Maximum expiratory pressure
How to perform the test
1. Disconnect the breathing valve from the front panel of the Quark
2. Connect the MIP/MEP valve to the breathing valve connector on the front panel of
the Quark and insert the flowmeter into the valve. Use a rubber mouthpiece
connected to the antibacterial filter and nose clip.
3. Select MIP/MEP from Test menu and wait for the green led is prompted on the
right side of the screen.
4. Breathe normally for some time.
5. Carry out a maximal expiration (for the MIP) or a maximal inspiration (for the
MEP).
6. Press F2 during the expiration/inspiration.
7. Inspire/Expire with the maximum force against the shutter until it opens
automatically.
8. Repeat the same procedure for the expiratory (inspiratory) maneuver. It is not
necessary to repeat the test since both MEP and MIP can be conducted during the
same acquisition.
9. Press F3 or wait the end of the test, so that the software displays the graphs, the
measured parameters, and the predicteds values.
