Hospitals often use code names to help alert medical staff

Hospitals often use code names to help alert medical staff in case of medical emergencies or other events. Codes can be announced through hospital speakers or communicated through an intercom in the hospital or directly to the required staff through devices such as pagers. The most common hospital codes are code blue, code red, and code black. These codes help trained medical staff to know the nature of the emergency, prepare themselves and respond quickly. These codes can prevent panic among other patients and visitors. Each code represents a different emergency, and they can also be used in other places besides hospitals, for example, schools, universities, law enforcement agencies, and other public places.

Code blue indicates a medical emergency such as cardiac or respiratory. Code red indicates fire or smoke in the hospital. Code black typically indicates there is a bomb threat. However, there is often a lack of standardization in the use of codes in the United States. For instance, in certain hospitals and institutions, code red and code blue are both used to refer to cardiopulmonary arrest. Although code blue typically refers to cardiopulmonary arrest in many hospitals, it does not necessarily mean the same thing everywhere. Each hospital, clinic, or other facilities can decide how they wish to manage and inform staff of potential emergencies. Other colors are also used to indicate other emergencies such as terrorist activity, child abductions, mass casualties, etc.

Common codes and their critical emergencies

Some of the common codes and their critical emergencies are described below.

Code blue: Code blue is the most universally recognized emergency code. It indicates a medical emergency occurring within the hospital that requires immediate medical attention. The hospital/clinic may choose how to activate a code blue. It may be by pushing an emergency alert button setting off an alarm, an announcement system using hospital speakers, dialing a specific phone number, or communicating with the required team through a direct paging system. Many hospitals, especially large hospitals, may have a code blue team who is dedicated to attending to code blue within minutes. The team typically comprises doctors, nurses, respiratory therapists, pharmacists, and other emergency care providers. In certain hospitals and institutions, code red and code blue are both used to refer to cardiopulmonary arrest. Although code blue typically refers to cardiopulmonary arrest and other medical emergencies at many hospitals, it doesn't necessarily mean the same thing everywhere because there is a lack of standardization.

Indications to activate a code blue include

Cardiac arrests such as a heart attack or serious arrhythmia (irregular heart rhythm)
Respiratory arrest (when the patient stops breathing)
Severe mental confusion
Signs of a stroke
A sudden drop in blood pressure

Cod red: Code red typically indicates a fire or smoke within the hospital. It may be activated if someone sees or smells smoke and/or flames.

Code black: Code black usually indicates a bomb threat. It may be activated if the staff or law enforcement officials have identified a possible bomb threat in or near the hospital.

Other codes

Hospitals, institutions, and other public places have numerous other codes, which include

Code pink: Infant or child abduction

Code orange: Hazardous material or spill incident

Code silver: Active shooter

Code violet: Violent or combative individual

Code yellow: Disaster

Code brown: Severe weather

Code white: Evacuation

Code green: Emergency activation

Benefits of codes

Codes are extremely helpful to maintain safety of people inside a hospital. They enable hospital staff, including doctors, to quickly identify and respond to emergencies and save lives. They avoid alarming other patients and hospital visitors unnecessarily because panic among bystanders can hinder the efforts of emergency responders.
