1. Minimal sedation (anxiolysis) |
a. Drug-induced sedation b. Patient responds normally to verbal commands c. Cognitive and motor function may be impaired d. Ventilatory and cardiovascular functions maintained normally |
2. Moderate sedation/analgesia (conscious sedation) |
a. Drug-induced sedation b. Patient responds purposefully to verbal commands either alone or with light tactile stimulation c. Patient maintains a patent airway and spontaneous ventilation d. Cardiovascular function maintained |
3. Deep sedation/analgesia |
a. Drug-induced sedation b. Patient cannot be easily aroused but can respond purposefully to repeated or painful stimulation c. Ventilatory function may be impaired, requiring assistance in maintaining a patent airway, and spontaneous ventilation may be inadequate d. Cardiovascular function is usually maintained |
4. General anesthesia |
a. Drug-induced loss of consciousness b. Patients are not aroused by painful stimulation c. Ventilatory function is often impaired; patient may require assistance in maintaining a patent airway d. Spontaneous ventilation may be impaired, as well as neuromuscular functioning e. Positive pressure ventilation is often required f. Cardiovascular function may be impaired |
