English to Portuguese Medical Medical: Instruments Sistema respiratório para anestesia

No contexto de um sistema fechado anestésico:

"Should the soda lime be suspected to have dried out or if a sharp temperature
increase is observed during the washing-in phase, or an unusual delay in the increase in inspired anaesthetic
concentration is observed, the soda lime absorber should be replaced with a fresh unit. Water
should never be added to try to correct for low moisture as this will decrease the efficiency
of the absorber due to local flooding."
