Selecting Measurement Manoeuvre - Dräger Evita 2 Instructions For Use Manual

Operation
Selecting measurement manoeuvre
Evita 2 can measure
occlusion pressure P 0.1
and
intrinsic PEEP
programme-controlled.
Using *occlusion pressure* measurement
Occlusion pressure', P 0.1, indicates the negative
pressure during short-term occlusion at the start of
spontaneous inspiration.
It is a direct measure of the functioning of the neuro-
muscular breathing drive.
For people with healthy lungs breathing quietly. P 0.1 is
3 - 4 mbar.
Values greater than 4 mbar indicate a high level of
breathing drive, which can only be maintained for a
limited time.
Values over 6 mbar indicate a risk of exhaustion in a
chronically-obstructed patient.
Measurement can only be carried out in the AS6
spent. mode, though preparation for measurement
can be done in other operating modes.
