So I'm going to use a half-faced gas mask (shown below) to inhale inert gas while lying on the bed. The mask is connected to a 4mm inner diameter oxygen tube, which will be connected to a gas-regulator set for 25 LPM and 0.2Mpa. But since I'm unsure if the tube can handle 25 LPM, I came up with another plan.
Here, I put a hole in a filter and ran a tube through it. This time the tube is a 10mm inner diameter, which should be more than enough to pass 25 LPM. These gray things are putty I used to seal the filter's air intakes. This solved the previous potential problem, but at the cost of reliability (like airtightness) since I made a lot of modifications.
Which do you think is better? Are there any issues with these setups?
I'm going to test both anyway, but I'd like to hear what others have to say about them. Thanks.
