5 Measurements
During the NIF operation, the patient circuit is blocked, and the low pressure generated by the patient
with respect to PEEP is measured. NIF is the patient’s maximum inspiratory effort. When the pressure
drop is less than -30 cmH2O, the probability of a successful extubation is higher.
The measurement result is written in the monitoring panel and in the trends, as well as a window
present during measurement.
The pressure curve is displayed on the upper part and the scale is changed so that it displays the neg-
ative pressures.
To activate the function, press the
[Measurements]
key and then press and hold the
[NIF]
key.
The LED lights up, and measurement begins, indicating the following message in the alarm panel: ‘NIF
measurement in progress’.
Note:
As long as the key is pressed, the procedure takes place, the circuit is blocked, and the
pressure drop generated by the patient is measured.
When the key is released, ventilation is resumed.
Note:
The maximum measurement duration is 30 s.
Note:
NIF measurement is accessible in all ventilation modes except CPAP, Duo-Levels and
APRV. It is not available in non-invasive ventilation, where the risk of leaks does not guarantee
reliable measurement.
Note:
The procedure may be interrupted by the raising of alarms such as Ppeak.
5.6 Manual Cycle
When the patient is in expiratory phase, an inspiratory cycle can be triggered manually (manual cycle).
To activate this function, press the
[Measurements]
key and then select
[Cycle.M]
when the patient is
in expiratory phase. The LED lights up and an inspiratory cycle is automatically launched, indicating the
following message in the alarm panel: ‘Manual cycle in progress’.
Note:
If the
[Cycle.M]
key is still pressed at the end of the inspiratory cycle, an inspiratory
plateau is then automatically applied.
