A patient in respiratory arrest at the scene of a mass-casualty incident would typically be classified as a fourth priority black tag expectant patient unless?

unless there are immediate and effective interventions available that could restore their breathing. If advanced airway management or resuscitation efforts can be initiated promptly, the patient may be reclassified to a higher priority for treatment. However, if their condition is deemed non-salvageable based on the resources available and the severity of injuries, they would remain a black tag expectant patient. Triage decisions are guided by the likelihood of survival and the capacity to provide care effectively.
