ASA 1级 无器官、生理、生化或精神系统紊乱。
举例：无。

ASA 2级 伴有系统性疾病，尚无功能受限。
举例：控制良好的高血压；非复杂性糖尿病。

ASA 3级 伴有严重系统性疾病，已出现功能不全。
举例：糖尿病伴血管系统并发症；既往心肌梗塞史。

ASA 4级 伴有严重系统性疾病，经常威胁着生命。
举例：充血性心力衰竭；不稳定型心绞痛。

ASA 5级 濒死病人，无论手术与否，不抱挽回生命的希望。
举例：主动脉破裂；颅内出血伴颅内高压。

ASA 6级 确证为脑死亡，其器官拟用于器官移植手术。
举例：ASA 1E病人脑死亡；又如健康病人急诊阑尾手术脑死亡

E 需要急诊手术的病例（在相应的ASA 级数之后加“E”字）。
