As a side note you should have a safety line tied to a fall harness you are wearing so if you do collapse then the buddy can haul you out, otherwise
if they come in to get you they'll die too or if they go get help you'll be dead before it arrives. Lastly even if a monitor shows now problems with
the air you breathing could depleate the oxygen or moving through liquid could release H2S or other toxins.
