Study summary

The purpose is to investigate how the adsorptive capacity of the active carbon filter to carbon dioxide in an anaesthetic gas reflector (AnaConDa) is affected by adding inhaled anaesthetic agent.

The hypothesis is that addition of inhaled anaesthetic agent will affect the amount of adsorption of carbon dioxide to the active carbon and thereby affect rebreathing of carbon dioxide.

What researchers measure

Primary outcomes

  1. Volume of carbon dioxide rebreathing from an anesthetic gas reflector

    Tidal carbon dioxide volume rebreathed from an anesthetic gas reflector correlated to concentration of delivered anesthetic gas.

    Time frame: 2 hours

Secondary outcomes

  1. Quantification of ventilatory requirements to maintain isocapnia with the use of an anesthetic gas reflector.

    Changes of tidal volume required to maintain constant alveolar ventilation will be assessed by continuous measurement of exhaled tidal carbon dioxide volume, the latter to be maintained at a constant value.

    Time frame: 2 hours
