Operation
Using nintrinsic PEEP<1 measurement manoeuvre
Intrinsic PEEP is the actual endexpiratory pressure in the
lung during ventilation with IPWKPPV.
Due to the dynamic effects of lung mechanics
(resistance, compliance, closing volume) and the
adjustment parameters of ventilation, the intrinsic PEEP
differs from the PEEP in the upper airways.
This procedure measures the 'happed' volume which
results from different PEEP values in the lung and which
is not part of gas exchange.
Measurement can only be carried out in the IPPV or
IPPWassist ventilation modes, though preparation for
measurement can be done in other ventilation modes.
