Fig. 6.6: Patient monitor.
The displayed parameters are immediate measured or calculated values. A column
scale is used to display the measured pressures in the airways within the range of -30 and 130
cmH
2
O. Two LED diodes, “trigger” and “pause”, inform the staff about each activation of the
patient’s trigger, or eventually in case there is an inspiratory pause “plateau“. The time the
LED diodes are lightened corresponds to the actual duration of the plateau. The plateau is
identified in case the measured decrease of pressure in time does not exceed 1 cmH
2
O/s.
Patient’s immediate ventilation parameters - These parameters may be measured
during each breath and subsequently displayed numerically.
Information on pressure:
P
peak
- peak pressure achieved during the entire breathing cycle is evaluated as of the
beginning of the next inspirium. Often labelled as PIP (Peak Inspiratory Pressure) in
literature.
P
mean
- shows the mean pressure of the previous eight breaths and is re-evaluated after
each breath.
P
pause
- final inspiratory pressure of the plateau is evaluated in case there is a real
plateau.
