At the beginning of 2020, a global alert emerged which saturated intensive care units dueto COVID-19 worldwide. This caused a need for mechanical ventilation due to atypicalpneumonias that had a rapid evolution and respiratory failure; therefore the consumptionof sedative agents in the intensive care units escalated. Suboptimal sedation in theintensive care unit, increases the adverse effects, costs, and morbidity. For the timebeing, they focus on the use of intravenous agents such as propofol or dexmedetomidine,which are associated with tolerance, withdrawal, delirium, and hemodynamic effects.Consequently, the need arises to maximize availability and effectiveness, which is whythe intervention of the ANACONDA conservation device is carried out, which works with aheat and humidity exchange filter capable of administering isoflurane or sevoflurane withan efficiency of 90%.
