because it allows reflection efficiency and has a small dead space, which allows use in ventilators even with small tidal volumes. The use of inhaled sedation has been shown to be useful as an alternative to deep intravenous sedation in a number of cases. Compared to conventional sedatives used in the Intensive Care Unit (propofol, midazolam, etc.), inhaled sedation provides safe sedation, which can be used for long periods of time, lacks accumulation, which allows faster awakenings with good hemodynamic safety. and with less association with the development of delirium, however, more studies are required on its use in critically ill patients.
