Inert gas with Helmet-Based Ventilator Assembly.

Helmet-Based Ventilator Assembly was a frequently used equipment for oxygen treatment during the pandemic. ( Basically it's a better version of nylon bag on one's head. ) I wonder if it could be used with inert gas as a cheaper and more portable alternative to Sarco.

The EEBD hood is pretty similar to that.
