Which ASA classifications are considered high risk?

Which ASA classifications are considered high risk?

• A. ASA I and II
• B. Unhealthy patients
• C. Low end doses
• D. ASA III-IV

Answer: (D)

Higher ASA physical status scores reflect greater risk from anesthesia because they indicate more severe systemic disease. ASA III represents severe systemic disease that limits activity, while ASA IV denotes severe systemic disease that is a constant threat to life. These categories identify patients who are at substantially higher risk during anesthesia and require careful preoperative optimization, tailored anesthetic planning, and enhanced intra- and postoperative monitoring. In contrast, ASA I and II describe healthy patients or those with only mild systemic disease, which correspond to lower anesthetic risk. The option combining ASA III and ASA IV best matches the high-risk range.
