Which levels of sedation are within the scope of procedural sedation?

• A. Minimal and Moderate
• B. Minimal and Deep
• C. Moderate and Deep
• D. Deep and Anesthesia

Answer: (C)

Procedural sedation covers the levels where the clinician can safely provide sedation and still manage the airway if needed. The levels within this scope are moderate (conscious) sedation and deep sedation.

In moderate sedation, the patient is not easily aroused but responds to verbal or light tactile stimulation and maintains airway reflexes and adequate breathing, with the clinician able to monitor and adjust sedation and provide analgesia as needed. In deep sedation, the patient is more depressed and may not respond except to repeated or painful stimulation; airway support and ventilation may become necessary, so the provider must be trained in airway management and ready to rescue from deeper levels in an appropriate setting.

Minimal sedation is simple anxiolysis with minimal impact on respiration, often considered outside the procedural-sedation scope, while anesthesia involves general or advanced airway management that typically requires separate anesthesia services. Therefore, moderate and deep sedation are the levels usually encompassed by procedural sedation.
