Which ESI Level requires high resource expectation and indicates an immediate threat to life?
Answer
Level 1
Level 1 in the Emergency Severity Index (ESI) algorithm is designated for patients requiring resuscitation due to an immediate threat to life. This level is strictly defined by its high resource expectation, specifically requiring immediate intervention to stabilize the patient. This contrasts with Level 2, which is also high risk but may require specialized attention quickly rather than immediate, life-saving procedural intervention, and Level 3, which requires physician evaluation but only a medium resource expectation.
