ASA Class I refers to a normal healthy patient who has no organic, physiological, biochemical, or psychiatric disturbances. This classification indicates that the patient is at the lowest risk for anesthesia-related complications, making them ideal candidates for elective surgery without additional perioperative considerations. Proper preoperative assessment confirms the absence of systemic disease, ensuring minimal impact on anesthetic management and surgical outcomes. This designation helps prioritize anesthesia care and risk stratification.
