High-frequency ventilation HFV (optional)
High-frequency ventilation around the PEEP/CPAP level,
which acts as the mean pressure.
The high-frequency pulses are superimposed at the selected
frequency around the mean pressure.
Suitable for patients with a body weight of up to about 2 kg,
for ventilating with reduced stress on the lungs.
Press the keys »Vent. Mode«, »CPAP« and »On«.
Press the key »Vent. Option«.
Press the key »HFV« and
move the cursor to the line »Frequ.« with the key »
«.
Adjust the frequency of the HF oscillations with the
keys »
« or »
«.
Move the cursor to the line »Ampl.« with the key »
«.
Adjust the amplitude with the keys »
« or »
«.
Press the key »On«.
Adjust the mean airway pressure with the rotary knob
»PEEP/CPAP«. This must be at least 3 mbar.
Observe the tidal volume VThf and/or the diffusion
coefficient DCO
and, if necessary, correct the amplitude
2
and frequency.
