 · Finally lower left figure the thermal heating in the reaction front indicative of CO 2 absorption effectiveness is fading out and the cooling of the canister from the surrounding cold water is beginning to win the tug of war between heat generation and conductive cooling At that point in time the canister is spent and essentially all of the exhaled CO 2 is passing right through the

CO2 Sensor AP Diving

The CO 2 canister duration within a rebreather varies with depth diver work rate temperature humidity and canister design An increase in depth or work rate can cause the CO 2 duration of a canister to shorten massively This doesn t matter greatly during the early phase of a dive on a fresh canister however if it occurs

Rebreather Wikipedia

A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user s exhaled breath to permit the rebreathing recycling of the substantially unused oxygen content and unused inert content when present of each breath Oxygen is added to replenish the amount metabolised by the user This differs from an open circuit breathing apparatus where the exhaled gas is discharged

The CO2 Scrubber in a Diver s Rebreather Shearwater Research

In fact CO 2 is the primary signal used by the body to control how much a person breathes the minute ventilation Similarly to the pO 2 in your rebreather it is the partial pressure of CO 2 pCO 2 that matters not the percentage fraction of CO 2 The average expired pCO 2 for a diver varies from some 2 5 to 4 kPa 25 to 40 mbar

Carbon dioxide scrubber Wikipedia

A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide CO 2 It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft submersible craft or airtight chambers Carbon dioxide scrubbers are also used in controlled atmosphere CA storage They have also been researched for carbon capture and
