It is an additional info used at the factory level, and not require to perform in the field.
Pls bear in mind that in between the fresh gas outlet to the complete flowmeter assembly, we have the flowmeter knob to control the flow as well, which will in turn further reduce the pressure.
All machines also have the low pressure safety relief valve at 5.5psi before gases coming into breathing system, then route it to patient.
So as long as there is no occlusion, nothing in this case will happen?
