The sensor on this unit has the advantage that it has a selective gas-permeable membrane that separates the detection electrode from the sample solution.
The nictitating membranes were retracted with phenylephrine hydrochloride, and the pupils were dilated with atropine sulfate, followed by application of gas-permeable contact lenses to protect the corneas.
Since the tube is highly gas-permeable, it guarantees optimal diffusion of gases between culture medium and internal atmosphere of the gas exchange module.
Membrane oxygenators introduce a gas-permeable membrane between blood and oxygen that decreases the blood trauma of direct-contact oxygenators.
For example, vessels lined with a highly gas-permeable material such as palladium (which is a high-capacity hydrogen sponge) create special outgassing problems.
Use of gas-permeable membranes may help in this regard as this allows increased exchange of water vapor and other gasses such as ethylene with the surrounding environment.
