Nitrogen with CPAP - Which tank?

[WeJumpToFly]

What liter tank of nitrogen is necessary when using a CPAP?

• 10 Liter Tank
  Container: sylinder 10 l (1.5 m3​)
  Gassmasse: 1.8 kg
• 40 Liter Tank
  Container: sylinder 40 l (6.3 m3​)
  Gassmasse: 7.5 kg

and does someone have a picture of a integrated flow regulator for nitrogen -> my native language isn't English, so I want to make sure I get the correct equipment.

Thanks so much.

I don't think you should use a CPAP mask. They all have ventilation holes. Here's what another forum member said:

"Leaving the holes open would bring in the air -- thereby oxygen -- during inspiration; whereas, closing the holes by masking them would trap the CO2 during expiration resulting in hypercapnia. CPAP masks are designed so that CBT is impossible."
