If, for example, a system has a defined leak, resulting in a continuous discharge of 3 L/min air, those 3 L/min are not included in the inspiratory volume. By entering • Base flow: 3.0 L/min the volume calculation could be corrected in our example. IMT Analytics AG...
This leads to false triggering! Here the flow must not be used as a trigger! The pressure curve must be used instead (8.5.3 Pressure curve upstream of the Y-piece). IMT Analytics AG...
Measuring errors due to the system as a whole occur both in the ventilator and in FlowAnalyser. However, the values indicated can vary because what was measured and compared may not be exactly the same. IMT Analytics AG...
