R
insp
- inspiratory resistance; this resistance represents the dynamic resistance of the
circuit, the endotracheal tube and the airways; this parameter is not evaluated in case
of selected sinusoidal and degressive flows and in spontaneous ventilation.
R
exp
- expiratory resistance; this resistance represents the dynamic expiratory decrease
of the pressure in the circuit, including the expiratory valve, the endotracheal tube and
the airways of the patient; this parameter is evaluated during spontaneous ventilation.
Information on trends:
All the parameters suitable for trends’ analysis may be stored and evaluated. These
parameters are labelled by the “T” symbol in the upper right corner of the button. They
are: lung compliance, spontaneous breathing activity, inspiratory resistance, expiratory
resistance and expired minute volume.
During standard use, the patient monitor evaluates immediate values breath by breath.
The trend is summoned by pushing the respective button and then selecting the 15 min
or 2 hour trend button. The trend is displayed within 10 s, and subsequently the
immediate values are displayed. When selecting a parameter that is not observed in
trends, the immediate value is always displayed.
