minimal sedation
what is this?
pt respond purposefully to verbal commands, either alone or accompanied by light tactile stimulation. no interventions are required to keep them breathing. cardiovascular function is usually maintained. Sometimes we see a drop in BP
moderate sedation
what is this?
pt cannot be easily around but respond purposefully following repeated or painful stimulation. May not be able to keep an open airway. pt may require assistance to breathe. cardiovascular function is usually maintained.
