What does a red arm band indicate in a healthcare setting?

In a healthcare setting, a red arm band typically indicates that the patient has an allergy. This visual alert is essential for staff to recognize and remember the potential for allergic reactions to specific medications, foods, or other substances. The use of color-coded bands is a safety measure aimed at preventing harm and ensuring that all personnel can quickly identify patients' special needs without having to review extensive medical records.

While other colored bands might signify different conditions or precautions—such as a yellow band for high fall risk, a green band for a specific medical condition, or a blue band for do-not-resuscitate orders—the red arm band is specifically designated for allergies. Implementing such a system enhances patient safety and improves communication among the healthcare team.
