This page covers 43 first aid words that start with E, running alphabetically from “Ecchymosis” to “Eye Wash.” These terms span injuries, medical emergencies, equipment, and body parts. They appear in training courses, emergency protocols, and clinical settings where fast, accurate communication can save lives.
First aid words are the shared vocabulary used by rescuers, paramedics, and medical teams to describe injuries, conditions, and emergency procedures clearly. Many of these terms trace back to Latin and Greek, which is why medicine still uses words like “emesis” instead of simply saying “vomit.” Knowing these words helps you understand what responders say and act more effectively in an emergency.
Below you’ll find the table with Word, Definition, and Description.

Descriptions
Ecchymosis
Ecchymosis, commonly called bruising, indicates trauma beneath the skin surface and can signal deeper tissue or organ damage in a patient.
Ectopic Pregnancy
Ectopic pregnancy is a life-threatening emergency causing severe internal bleeding; symptoms include sudden abdominal pain, dizziness, and shoulder pain.
Edema
Edema appears as visible puffiness or swelling and can signal injury, allergic reaction, infection, or an underlying medical condition requiring attention.
Elastic Bandage
Elastic bandages are versatile first aid tools for managing sprains, strains, and controlling bleeding through sustained compression on a wound.
Electrocution
Electrocution can cause burns, cardiac arrest, and nerve damage; rescuers must ensure the power source is off before approaching or touching the victim.
Elevation
Elevating a wounded limb slows blood loss and minimizes swelling, and is commonly used for sprains, fractures, and actively bleeding wounds.
Embolism
An embolism, particularly in the lungs, is a medical emergency causing chest pain and breathlessness that can rapidly become life-threatening.
Embolus
An embolus lodged in the lungs or brain can be rapidly fatal; first aiders should call emergency services immediately and keep the patient still and calm.
Emergency
Any unexpected event posing an immediate risk to health or life that demands a prompt, organized response to protect the person affected.
Emergency Exit
Emergency exits must be clearly marked, unobstructed, and familiar to all building occupants to enable swift escape during fires or other crises.
Emergency Medical Services
EMS dispatches trained personnel and equipment to the scene of medical emergencies to stabilize patients and transport them to hospital.
Emergency Medical Technician
EMTs respond to 911 calls, assess patients, administer basic treatments, and transport victims to hospital under established medical protocols.
Emergency Response
Emergency response encompasses calling for help, assessing scene safety, providing first aid, and supporting victims until professional help arrives.
Emergency Surgery
Emergency surgery may be needed after severe trauma, internal bleeding, or organ perforation and must be performed without delay to save the patient’s life.
Emphysema
Emphysema causes progressive breathlessness; first aiders should keep the patient calm, seated upright, and call for emergency medical assistance promptly.
Emesis
Emesis is a common response to poisoning, head injury, or shock; proper positioning of the patient is critical to prevent aspiration into the lungs.
Encephalitis
Encephalitis presents with fever, severe headache, and confusion progressing to seizures; it is a medical emergency requiring immediate hospitalization.
Endotracheal Tube
Endotracheal intubation is performed by paramedics or doctors to secure the airway in unconscious or critically ill patients who cannot breathe adequately.
Entrapment
Entrapment occurs most commonly in vehicle accidents and requires specialized rescue teams with cutting tools for safe removal without worsening injuries.
Environmental Hazard
Environmental hazards include extreme temperatures, toxic substances, electrical risks, and unstable structures that rescuers must identify and avoid.
Epidermis
The epidermis is most often affected in superficial burns and abrasions; even minor damage requires proper wound care to prevent infection.
Epilepsy
Epilepsy requires first aiders to protect the patient from injury during a seizure, maintain airway patency, and avoid restraining the person’s movements.
Epinephrine
Epinephrine is the primary drug used during anaphylaxis, rapidly reversing life-threatening symptoms like airway swelling, hives, and dangerously low blood pressure.
EpiPen
EpiPens are carried by people with severe allergies for self-injection during anaphylactic shock, providing fast epinephrine delivery into the outer thigh.
Epistaxis
Epistaxis is managed by leaning the patient slightly forward, pinching the soft part of the nose firmly, and breathing through the mouth for 10–15 minutes.
Erythema
Erythema is commonly seen in burns, rashes, allergic reactions, and infections, indicating that tissues are under stress and require assessment.
Escharotomy
Escharotomy is performed when circumferential burns restrict blood flow to a limb or breathing in the chest; it is a procedure for trained medical professionals only.
Esophageal Obstruction
An esophageal blockage requires immediate emergency services; if the airway is compromised, standard choking procedures may be attempted while awaiting help.
Esophagus
The esophagus is relevant in first aid during chemical ingestion, choking events, and certain penetrating neck injuries that require urgent care.
Evacuation
Evacuation in first aid involves moving injured or at-risk individuals away from hazards, especially fires, gas leaks, or structural collapses, to safety.
Evaporation Cooling
Evaporation cooling is used for heat stroke; misting the skin with cool water and fanning the patient rapidly lowers dangerous core body temperature.
Evisceration
Evisceration requires covering exposed organs with a moist, non-stick sterile dressing and calling emergency services immediately; organs must never be pushed back in.
Examination
A thorough examination helps rescuers prioritize life-threatening problems like bleeding, breathing difficulty, and altered consciousness before beginning treatment.
Exhaustion
Heat exhaustion, a serious form, causes heavy sweating, weakness, and dizziness; treatment involves cooling the patient and providing oral fluids if conscious.
Exit Wound
Exit wounds are typically larger and more ragged than entrance wounds, helping responders estimate the path of injury and direct hemorrhage control efforts.
Expired Air Resuscitation
Expired air resuscitation, or rescue breathing, delivers oxygen to a non-breathing patient and is used alongside chest compressions in full CPR.
Exposure
In first aid, exposure can refer to chemical contact, radiation, bloodborne pathogen contact, or environmental cold or heat that threatens a person’s health.
External Bleeding
Controlling external bleeding through direct pressure, wound packing, elevation, and bandaging is one of the most critical and immediately lifesaving first aid skills.
Extinguisher
Fire extinguishers are essential emergency tools in workplaces and homes; first aiders should know the PASS technique: Pull, Aim, Squeeze, Sweep.
Extrication
Extrication from vehicles or collapsed structures demands specialized equipment and trained rescue personnel to avoid worsening the victim’s spinal or other injuries.
Eye Injury
Eye injuries range from minor irritation to sight-threatening lacerations; most require covering the eye with a sterile pad and seeking urgent medical attention.
Eye Protection
Safety goggles and face shields are standard first aid PPE, preventing rescuers from making mucosal contact with a patient’s blood or bodily fluids.
Eye Wash
Immediate eye washing for at least 15 minutes is the standard first aid response to chemical splashes to dilute and remove the hazardous substance.
