PEEPfinder manoeuvre
With the PEEPfinder, the device offers a respiratory mechanics manoeuvre during
which a quasi-static P/V graph (pressure/volume) is recorded at the bedside and
which assists in determining a secure window for the ventilation settings. The
PEEPfinder can optionally be used as a recruitment tool.
Remark
The extent of the manoeuvre (only inspiratory measurement, only
expiratory measurement, or inspiratory and expiratory measure -
ment) can be set on the configuration level.
A pre-oxygenation function with an adjustable oxygen concentration can be acti -
vated to prevent inadequate oxygen supply during the manoeuvre.
Depending on the configuration, the manoeuvre covers only the inspiratory por -
tion, only the expiratory portion, or the entire breath.
The measured data may prove very useful for the clinical diagnosis as well as for
optimizing the ventilation settings.
A 2.6.1
Prerequisites
Conditions for using PEEPfinders are:
• The patient must be intubated or tracheotomized and ventilated.
• The device passed the system test successfully (including measurement of the
breathing circuit).
• Only mandatory ventilation is applied, the patient is not breathing spontane-
ously. In spontaneous breathing modes, during HFOT or non-invasive ventila-
tion, the PEEPfinder function is deactivated.
• The overall leakage is low.
A 2.6.2
Contraindications
Possible contraindications for using PEEPfinder:
• Patients breathing spontaneously or with phases of spontaneous respiration
• Patients whose cardiovascular condition is unstable
• Hypovolaemic patients
• Patients with suspected or confirmed intracranial pressure problems
• Patients unable to tolerate elevated intrapulmonary pressures for other rea -
sons
• Patients unable to tolerate extended ventilation pauses
• Patients susceptible to barotrauma or volutrauma
• Patients with an inadequate depth of sedation and level of relaxation
