Why can you see deviations in compliance values on the SmartLung 2000?

The SmartLung 2000 enables various compliance values to be set (simulation of lung stiffness). The smallest (at the same time also the hardest) compliance setting is 25 mL/mbar at a volume of 1000 mL.

The silicone bag of the SmartLung 2000 has a production tolerance which can lead to the bag popping out a little at the side at a volume of 1000 mL. This can lead to the compliance value deviating from 25 mL/mbar and becoming larger.

Use a smaller volume of approx. 500 - 600 mL to achieve a compliance of 25 mL/mbar.
