In hospitals, doctors and paramedics use the term clear to warn others to stay away from a patient who is about to be shocked with a defibrillator. This is because defibrillators pass an electric current through the patient's body, and if anyone else is touching or has any physical contact with the patient, they may also get shocked. The term clear is used to ensure the safety of both the patient and the medical staff.

What You'll Learn
To prevent others from getting shocked
In medical emergencies, time is of the essence. When a patient's heart is not beating in a regular rhythm, a defibrillator may be used to deliver a controlled amount of electric current (called 'countershock') to the heart. This current can reset the heart, stopping it completely before it resumes beating in a rhythmic pattern.
Before placing the paddles of a defibrillator on the patient's body, doctors or paramedics will shout 'Clear!'>. This is to ensure that no one is touching or has any physical contact with the patient when the shock is administered. The electric current can pass through the patient's body and into anyone else who is in contact with them, shocking them too.
The 'Clear!' call is a safety measure to protect others from getting shocked. It is a standard procedure that is taught in EMT schools and is part of emergency service personnel's duty to keep themselves safe so that they can effectively carry out their jobs.
In addition to preventing shocks to medical staff, the 'Clear!' call also serves another important purpose. During a medical emergency, there may be multiple people around the patient, performing various tasks such as CPR, ventilation, feeling for a pulse, and administering medications. By calling 'Clear!', everyone is alerted to quickly step away from the patient, ensuring that no one accidentally comes into contact with the patient during the critical moment of shock delivery.
While modern defibrillators often use stickers placed on the patient's back and chest instead of paddles, the 'Clear!' call remains essential. It ensures the safety of the medical team and helps prevent unintended consequences, such as interference with the patient's treatment or, in rare cases, severe trauma to the patient.

To ensure no physical contact with the patient
In a hospital setting, it is imperative to ensure that there is no physical contact with the patient when using a defibrillator. This is because defibrillators deliver a controlled electric current, known as a "countershock," to the patient's heart to reset it and restore a regular heartbeat.
Shouting "Clear!" is a standard safety protocol in hospitals to ensure that no one is touching the patient when the electric shock is administered. This warning call is crucial because if anyone is in physical contact with the patient, the electric current may pass through them as well, potentially causing harm.
The "Clear!" shout serves as a loud and clear signal to alert everyone in the vicinity to step away from the patient immediately. It is a way to ensure that everyone, including medical staff and other personnel, is aware that a shock is about to be delivered and that no one should be in contact with the patient at that moment.
In some cases, it may be necessary to perform chest compressions or cardiopulmonary resuscitation (CPR) on the patient right up until the moment the shock is delivered. However, it is essential to ensure that all physical contact ceases before administering the shock to avoid any accidental electric shocks to medical personnel or bystanders.
The "Clear!" call is, therefore, a critical safety measure to protect both the patient and those around them from potential harm during the use of a defibrillator. It ensures that there is no physical contact with the patient, reducing the risk of electric shock to anyone other than the patient.

To avoid interference with the defibrillator
Defibrillators are used to treat life-threatening conditions when a patient's heartbeat becomes irregular, either too slow or too fast. This condition is called heart arrhythmia. When using a defibrillator, doctors loudly say "Clear" to warn others to stay away from the patient. This is because defibrillators deliver a controlled amount of electric current through the patient's body, and if anyone else is touching or has any physical contact with the patient, they may also get shocked.
The purpose of the shock is to reset the heart, and it can cause the patient's muscles to contract, making them flail around and possibly hurt people nearby. Therefore, it is essential to ensure that everyone is clear of the patient before administering the shock.
The phrase "clear" is also used as a form of confirmation by medical professionals. Before delivering the shock, they will confirm that they themselves are not touching the patient and then instruct others to do the same. This is especially important when using manual defibrillators with handheld paddle electrodes, which can cause stray electric currents if not properly handled.
In addition to preventing accidental shocks, saying "clear" also serves as a reminder to check that no one is touching the patient. This is a critical step, as having physical contact with the patient during defibrillation can interfere with the treatment's effectiveness and potentially harm both the patient and the person touching them.
While it may seem unnecessary for trained medical staff to shout "clear," it is a crucial safety measure. It ensures that everyone involved is aware of the imminent shock and can take the necessary precautions. This simple word can help prevent accidental injuries and ensure the best possible outcome for the patient.

To maintain the safety of the medical team
In a hospital setting, it is crucial to prioritise the safety of the medical team, comprising doctors, nurses, and other healthcare professionals. One of the critical aspects of ensuring their safety is by establishing clear communication and protocols, especially during emergency procedures such as defibrillation.
During a medical emergency, such as a patient experiencing cardiac arrest, the medical team's primary focus is on providing life-saving treatment. However, in the rush to administer care, it is vital to ensure that the team members themselves remain safe and do not inadvertently harm themselves or each other. This is where the practice of shouting "Clear!" comes into play.
Shouting "Clear!" is a standard protocol followed by medical professionals before using a defibrillator on a patient. This loud and clear announcement serves as a critical warning to ensure that no one is physically touching the patient when the electric current is delivered. This is of utmost importance because if anyone is in contact with the patient during defibrillation, they may also receive an electric shock, which can be dangerous and, in some cases, life-threatening.
The act of shouting "Clear!" is, therefore, a crucial safety measure to protect the medical team. It ensures that everyone involved in the procedure is aware that a shock is about to be administered and provides them with the opportunity to physically separate from the patient and avoid any potential harm. This practice aligns with the principle that emergency service personnel have a duty to keep themselves safe to remain fit to carry out their jobs effectively.
Additionally, it is worth noting that advancements in medical technology have led to the development of automated external defibrillators (AEDs), which are designed for use by laypersons outside of hospitals. These devices play a recorded message instructing bystanders to "Stay clear of the patient" before delivering the shock. This further highlights the importance of ensuring that no one is in contact with the patient during defibrillation, regardless of the setting.

To prevent harm to the patient
In a hospital setting, it is crucial to prioritize patient safety and prevent any potential harm. One of the critical measures to ensure this is by shouting "Clear!" before using a defibrillator on a patient. This practice is not just dramatized in movies and TV shows but is an essential step in real-life medical emergencies.
When a patient experiences an irregular heartbeat, either too slow or too fast (known as heart arrhythmia), they may require defibrillation. This involves delivering a controlled electric current or 'countershock' to the patient's heart to reset it and restore a regular rhythm. However, this process can be extremely dangerous if anyone else is in physical contact with the patient.
Shouting "Clear!" is a loud and clear warning to ensure that all medical personnel and bystanders are not touching the patient as the electric current is administered. This is important because if anyone is in contact with the patient, the electric current can pass through them as well, potentially causing serious harm or even death.
Additionally, the "Clear!" call is essential because, until the shock is delivered, constant CPR, ventilation, pulse-checking, and medication administration are required. This means that multiple people may have their hands on the patient right up until the moment the shock is given. Shouting "Clear!" ensures that everyone knows to let go and step away, protecting both the patient and the medical team from potential harm.
Moreover, the "Clear!" instruction is not limited to defibrillation procedures. It is also used when starting IVs, placing urinary catheters, or inserting Naso-gastric tubes. This universal warning ensures that the patient's bed area is safe and that no one is accidentally harmed during these delicate procedures.
