AMSORB® PLUS

Key Details

AMSORB® Plus absorbs carbon dioxide from cellular respiration during anaesthesia.

Why change to AMSORB® Plus

AMSORB® Plus is the world’s first CO₂ absorbent to be free of strong alkali. It offers significant clinical, cost and environmental advantage.

AMSORB® Plus is easier to use

AMSORB® Plus retains its desiccated colour change. Available in prefill cartridges compatible with most common anaesthesia machine brands.

AMSORB® Plus is safer

Unlike other absorbents, AMSORB® Plus is incapable of anaesthetic degradation and does not produce harmful by-products.

AMSORB® Plus is better for the environment

AMSORB® Plus is free of strong-base chemicals, therefore, the material is non-hazardous, safe to handle during handling and disposal, and is suitable for landfill.

AMSORB® Plus is cost effective

AMSORB® Plus demonstrates the least potential to delay inhalational induction at any flow rates. Ahmed et al. 2011 demonstrated 25.7% annual anaesthetic gas savings.

AMSORB® Plus is designed for low flow anaesthesia

AMSORB® Plus is safe for use at low and minimal flow rates. It will not adsorb anaesthetic agent and is not capable of agent degradation.

AMSORB® Plus - Supporting Sustainable Anaesthesia

FREE OF STRONG ALKALI

AMSORB® Plus can contribute to your hospital’s sustainable anaesthesia strategy

Reduced Anaesthetic Gas Consumption

With no strong alkali present, AMSORB® Plus enables safe, low and minimal flow anaesthesia, with reduced adsorption of anaesthetic vapour.

Reduced Absorbent Waste

The permanent colour change of AMSORB® Plus is an accurate visual indicator of granule exhaustion giving confidence to use AMSORB® Plus until FiCO2 reaches 0.5mmHg maximising length of use and reducing waste.

Prefilled canisters are autofilled to ensure reduced intergranular space, maximising absorbent weight per canister and optimising gas flow with improved absorption efficiency.

Prefilled canisters can be easily replaced mid procedure utilising absorption capacity until breakthrough and reducing waste associated with pre-emptive change.

Non-Hazardous Waste

As AMSORB® Plus is non caustic, it may be disposed of in domestic waste (in accordance with local waste management policy).

Desiccated Sodalime >pH12.5
Desiccated AMSORB® Plus <pH12.5 

 

The Enviromental Impact of Anaesthesia

Inhalation anaesthetic gases contribute to climate change – accounting for 5% of NHS CO2 emissions. 2% (590,000 ton) of all UK industrial and commercial waste is generated by the NHS.1
Each UK operating room generates between 52-78kg of hazardous soda lime waste per year – equivalent to 166-249 ton in the UK.2

Single Site Manufacturing

Reduced carbon footprint from single site manufacturing.

When to exchange?

AMSORB® Plus is NOT the same as Sodalime

No production of CO or Compound A (even when desiccated). Low flow and closed-circuit techniques are safer, even with sevoflurane.

Discard as non-hazardous waste. AMSORB® Plus exhausted pH <12.5, is safe for landfill and breaks down to harmless inorganic compounds.

How AMSORB® Plus works

The primary reaction is between CO₂ and calcium hydroxide (Ca(OH)₂) and water. These form calcium carbonate (CaCO3) and water. Exothermic heat is a by-product of absorption. During absorption, Ca(OH)₂ is continually re-moistened until converted to CaCO3. Lesser chemicals, calcium chloride (CaCl₂) and calcium sulphate (CaSO4) prolong the life of Ca(OH)₂ and increase the speed of absorption reaction by maintaining granule strength and optimising hydration.

Chemical Reaction of Absorption
Ca(OH)₂ + CO₂ >>>>> CaCO3 + H₂O
Slightly soluble  >>>>> Insoluble

Ca(OH)₂ is an ionic compound which is soluble in water at 0.5g/L at 20°C:

  • The ions are Ca++ and OH-OH-
  • CO₂ is soluble in water at 1 vol : 1 vol at 20°C
  • CaCO3 is an insoluble ionic compound Ca++ and CO3- –

Reactions take place in solution when particles are mobile and react on collision
A colour indicator is present, changing from WHITE (fresh) to VIOLET upon exhaustion or desiccation.

The indicator reacts to changes in granule hydration as absorption progresses; eventually remaining violet-coloured, once absorption is complete. Colouration also results from contact with ambient air or oxygen, if exposed to these.
