Code blue is a hospital emergency code used to describe a patient's critical status. It is often used to indicate that a patient is experiencing cardiopulmonary arrest and requires immediate resuscitation or medical attention. Hospital staff may call a code blue in cases of cardiac or respiratory arrest, or other medical emergencies. Code blue alerts are usually accompanied by a specific location, such as the floor and room number, to direct the response team to the patient. Hospitals typically have rapid response teams ready to respond to code blue situations, and these teams often consist of physicians, nurses, and other medical professionals with advanced resuscitation training.

What You'll Learn
Code Blue indicates a critical medical emergency
Code Blue is a hospital emergency code that indicates a patient requires resuscitation or is in need of immediate medical attention due to a critical medical emergency, most often as a result of cardiac or respiratory arrest. It is used to communicate the critical status of a patient and is often accompanied by a specific location description to alert the resuscitation team where to respond.
The code blue call takes the form of "Code blue, [floor], [room]", and hospitals typically have rapid response teams ready to go when notified about a code blue. The resuscitation is usually done by the "code team" of the hospital, which includes a physician who serves as the team leader and directs the resuscitation effort. Other team members include a unit RN who assists the team and a critical care/ICU RN who manages and monitors the defibrillator and cardiac rhythm strips.
The hospital's response to a code blue varies depending on the patient's condition. Doctors typically take charge of the situation and may start performing CPR or intubating the patient to aid in resuscitation efforts. If a patient's heartbeat is irregular, staff may use an automated external defibrillator (AED) to reestablish a stable heart rhythm or administer medications like epinephrine or naloxone.
Code blue is a fairly universal term used by most medical institutions worldwide to indicate a critical medical emergency. However, there is currently no national standard for emergency codes, and codes may vary between hospitals.

Cardiac arrest and resuscitation
"Code Blue" is a hospital emergency code used to describe the critical status of a patient. It is often used to indicate that a patient is in cardiac arrest and requires resuscitation. When a code blue is called, it typically takes the form of "Code blue, [floor], [room]" to alert the resuscitation team, which includes medical doctors, nurses, and other healthcare professionals with advanced cardiac life support or equivalent resuscitation training.
Cardiac arrest is the sudden cessation of cardiac activity, resulting in the victim becoming unresponsive, with no normal breathing and no signs of circulation. It is a life-threatening condition that requires immediate medical attention and corrective measures to reverse the condition, usually through cardiopulmonary resuscitation (CPR) and/or defibrillation.
The treatment of cardiac arrest has evolved over time, progressing from internal defibrillators to external manual and automated defibrillators. Modern treatment approaches for patients who have suffered prolonged cardiac arrest include therapeutic hypothermia, strategies for pulseless electrical activity, and aggressive post-resuscitation care.
When responding to a code blue, healthcare professionals may perform CPR, intubate the patient to aid in resuscitation efforts, and employ an automated external defibrillator (AED) to reestablish a stable heart rhythm. If the patient's heartbeat is irregular, they may also administer medications such as epinephrine or naloxone.

Respiratory issues and intubation
"Code blue" is a hospital emergency code used to describe the critical status of a patient. Hospital staff may call a code blue if a patient is in respiratory distress, which can include airway blockage or damage, loss of consciousness, or respiratory failure.
Intubation is a life-saving procedure commonly performed during a code blue activation to open the patient's airway and aid breathing. It involves inserting an endotracheal tube through the patient's mouth or nose, into their trachea, to ensure oxygen reaches their lungs. This procedure is often accompanied by anaesthesia and the use of a laryngoscope to guide the tube.
The type of tube used during intubation depends on the reason for the procedure and its expected duration. Standard PVC tubes are common due to healthcare costs, but they can overinflate and cause tracheal damage. Polyurethane tubes are safer and more effective, especially the barrel-shaped cuff design, which minimises trauma and prevents microaspiration.
While intubation is life-saving, it is also invasive, and clinicians must balance the benefits with potential complications, such as ventilator-associated pneumonia. Clinicians are focused on limiting invasive ventilation and finding alternative treatment methods to shorten the time patients spend on ventilators.

Non-standardised codes
Hospital emergency codes are used to alert staff to an emergency or significant event. They are intended to convey essential information quickly and accurately, while also preventing panic among patients and visitors. While some hospitals have adopted standardised codes, there is no national standard for emergency colour codes, and codes can vary widely between hospitals, even within the same community.
- Code Black: In the UK, this means the hospital is at capacity with no available beds for new admissions. In Australia, this means security is needed as someone is armed and a threat to themselves or others. In some US states, this indicates a weather warning.
- Code Grey: In some hospitals, this indicates a combative person, a physical threat requiring security, or a psychiatric emergency.
- Code White: This can mean a paediatric medical emergency, a combative person without a weapon, or emergency operating procedures, depending on the state. In some hospitals, it indicates a violent individual on the premises or a missing child.
- Code Orange: This often indicates a hazardous material spill or medical decontamination. It can also be used to indicate a bomb threat.
- Code Green: This can mean different things in different hospitals. It can indicate patient elopement (a patient has left the premises without supervision) or that staff need to evacuate a certain area.
- Code Purple/Pink: These often indicate a missing child or child abduction.
- Code Amber: Indicates a child abduction or attempted child abduction.

The Code Team
"Code Blue" is a hospital emergency code used to describe the critical or deteriorating status of a patient. It is often used when a patient goes into cardiac arrest, experiences respiratory issues, or faces any other medical emergency.
- Physician or Medical Doctor: Serves as the code team leader and directs the medical management of the team. They may also perform CPR and intubate the patient by inserting an endotracheal tube through the patient's mouth or nose and into their trachea.
- Unit RN: Assists the team as needed and initiates basic life support.
- Critical Care/ICU RN: Serves as the initial code team leader until the physician arrives. They manage and monitor the defibrillator and cardiac rhythm strips, relaying ECG findings to the physician and nurse documenting the code. They also administer emergency drugs as directed.
- Nurse documenting the code: In charge of documentation and relaying information to the physician.
- Pharmacist: Prepares emergency medications, calculates infusion rates, ensures drug incompatibilities are avoided, and restocks the e-cart.
- Fourth Responder: Ensures that IV fluids and emergency medications are ready for use by the Code Team.
Preparing for a Code Blue
To prepare for a Code Blue, healthcare institutions usually conduct mock codes, especially for new nurses, to familiarise them with the hospital's policies and procedures during a Code Blue. It is important for nurses to actively participate in these mock codes and seek certifications like Basic Life Support (BLS) and Advanced Cardiac Life Support (ACLS) to enhance their skills and confidence in responding to Code Blue situations.
Responding to a Code Blue
When a Code Blue is activated, the Code Team springs into action. The initial resuscitation efforts are typically carried out by the nearest nurses on duty until the Code Team arrives. Once on the scene, the Code Team leader, usually a physician, takes charge and directs the ongoing resuscitation efforts. The team works together to stabilise the patient, utilising their specific roles and expertise.
Post-Code Blue Debrief
After a Code Blue, it is essential to debrief with the team. This allows for a discussion of what went well and what areas need improvement. Debriefing enhances the team's skills and knowledge, ensuring a more refined response to future Code Blues.

Frequently asked questions
"Code blue" is used to indicate that a patient is experiencing a medical emergency, such as cardiac arrest, and requires immediate resuscitation.
A hospital's response to a code blue call will vary depending on the patient's condition. Typically, medical doctors take charge of the situation. If the patient has stopped breathing or their heart has stopped, staff will perform CPR and other resuscitation efforts.
Hospitals have different code team members, but they usually include a physician, unit RN, critical care/ICU RN, and a pharmacist. The physician serves as the team leader and directs the rest of the team. The unit RN assists the team and provides basic life support, while the critical care/ICU RN manages and monitors the defibrillator and cardiac rhythm strips. The pharmacist prepares emergency medications and ensures drug incompatibilities are avoided.
It can be scary for new nurses to experience a code blue situation for the first time, so it is important to participate in mock codes and get certified in Basic Life Support (BLS) and Advanced Cardiac Life Support (ACLS) trainings. During a code blue, nurses should be active with the code team and participate in the resuscitation efforts until the code team arrives. After the code blue situation has been resolved, it is important to debrief with the team to discuss what went well and what can be improved.
