How to maintain a healthy atmosphere inside a hyperbaric chamber

Hyperbaric chambers are sealed pressure vessels. This means that the atmosphere inside the hyperbaric chamber quickly becomes polluted with CO2 from exhaled air. High concentrations of CO2 can be poisonous and must be removed from the chamber atmosphere.

The innovative IHC Hytech CO2 scrubber has been specially designed to remove CO2 from the atmosphere of hyperbaric chambers. The scrubber is equipped with an induced flow fan which pulls the polluted air through a canister filled with soda lime to adsorb the CO2.

Refillable canister
The scrubber comes with a refillable canister which can hold approximately 7.5 kg of CO2 adsorbent. This canister is connected to the motor by a bayonet locking mechanism allowing for easy replacement. One canister is enough for eight people for up to six hours in a chamber with adequate gas circulation.


Contamination canister
Optionally, a contamination canister can be used to remove other contamination caused by humans. The contamination canister contains a special blend of carbon molecular sieves which eliminate the following chemical components:

  • Urea (NH2)2CO from urine
  • Carbon monoxide (CO) from endogenous production
  • Acetone (GH3 COCH3) from metabolic and organic waste
  • Hydrogen chloride (HCL) from vomit
  • Hydrogen sulphide (H2S) from feces/intestinal gas
  • Carbonyl sulphide (OCS) from intestinal gas
  • Hydrogen (H) from intestinal gas
  • Methane (CH4) from intestinal gas
  • Carbon disulphide (CS2) from intestinal gas
  • Butyric acid (C3H1COOH) from intestinal gas
