| breathe out
just try this as an experiment, fully exale , now time yourself to when you need to breathe again , this is the time you need to find your buddy and get his AAS or bolt for the surface , or you reach for your pony reg take a deep breathe and thank the day you invested in a redundant air supply. at the end of the day you can weigh up the pros and cons and make a choice
