This page covers 27 first aid words that start with G, running from “Gauze” to “Gingiva.” The list includes supplies, body parts, medical procedures, emergency concepts, and assessment tools. Together, these terms make up a useful slice of the language used during emergencies and basic medical care.
First aid words are the terms used to describe injuries, equipment, anatomy, and treatments in emergency situations. They form the shared language between bystanders, paramedics, and hospital staff. The concept of organized first aid training — and with it, a standardized vocabulary — gained wide adoption after the Red Cross launched its first public courses in the 1880s.
Below you’ll find the table with Word, Definition, and Description.
Word: The specific term you may encounter in first aid manuals, training courses, or emergency scenarios — useful for quick recognition and clear communication.
Definition: A plain-language explanation of what each word means at its most basic level, so you can build a solid understanding without needing a medical background.
Description: A practical look at how and when each term comes up in real first aid situations, helping you connect the word to what actually happens on the ground.

Descriptions
Gauze
Gauze is one of the most common first aid supplies, used to cover wounds, absorb blood, and secure bandages. It comes in rolls, pads, and sterile packages for various wound types.
Gloves
Disposable gloves — usually latex or nitrile — are essential personal protective equipment in first aid, preventing the spread of bloodborne pathogens between the rescuer and patient.
Gurney
A gurney allows emergency personnel to safely move injured or ill patients without worsening injuries. Most feature adjustable heights and safety rails to secure the patient during transport.
Glucose
In first aid, glucose tablets or gel are given to conscious patients experiencing hypoglycemia (low blood sugar) to quickly raise blood glucose levels and prevent loss of consciousness.
Golden Hour
The golden hour concept emphasizes that survival rates for severe trauma victims improve dramatically when definitive care is delivered within the first hour of injury.
Glasgow Coma Scale
The GCS evaluates eye opening, verbal response, and motor response, yielding a score from 3 to 15. It helps first responders quickly gauge the severity of a brain injury.
GCS
GCS is widely used by paramedics and emergency responders to document a patient’s neurological status and track changes over time during emergency care.
Gash
A gash typically requires more than basic first aid — deep gashes may need professional wound closure with sutures or staples to stop bleeding and prevent infection.
Goggles
Goggles are standard personal protective equipment for first aiders working with bleeding wounds, as splashing body fluids can transmit infectious diseases through mucous membranes.
Graze
Grazes are among the most common minor injuries treated with first aid. They should be cleaned with clean water, dried, and covered with a sterile dressing to prevent infection.
Gunshot Wound
Gunshot wounds require immediate first aid to control hemorrhage, including direct pressure and — for limb wounds — tourniquet application, while awaiting emergency medical services.
Gag Reflex
The gag reflex helps prevent choking and aspiration. In unconscious patients it may be absent, increasing the risk of airway obstruction and requiring careful positioning.
Gastric Lavage
Also called stomach pumping, gastric lavage is used in poisoning emergencies. It is performed by medical professionals and is not a standard lay first aid technique.
Gas Gangrene
Gas gangrene, caused mainly by Clostridium bacteria, spreads rapidly and can be fatal within hours. It requires immediate surgical debridement and is a medical emergency beyond basic first aid.
Gangrene
Gangrene can follow severe wounds or crush injuries when blood flow is cut off. First aiders should recognize signs such as blackened tissue or foul odor and call emergency services immediately.
Guedel Airway
Named after Dr. Arthur Guedel, this curved plastic tube holds the tongue away from the back of the throat. It is used by trained first aiders and paramedics to maintain an open airway.
Groin
The groin contains major blood vessels, including the femoral artery. Bleeding wounds here are serious and require firm direct pressure since tourniquet application is not possible in this area.
GSW
GSW is standard shorthand in emergency documentation. Knowing this abbreviation helps first aiders communicate quickly and clearly with incoming paramedics and trauma teams.
Grip Strength
First aiders and paramedics assess grip strength by asking patients to squeeze both hands simultaneously. Weakness or asymmetry can indicate stroke, nerve injury, or spinal cord damage.
Ground-Level Fall
Ground-level falls are a leading cause of head and hip injuries, particularly in older adults. First aiders should suspect spinal injury and keep the patient still until emergency services arrive.
Germ
In first aid, preventing germ transmission means cleaning wounds thoroughly, using gloves, and keeping dressings sterile. Germs entering open wounds can cause serious infections like sepsis.
Glottis
The glottis is a key anatomical landmark during airway management. An obstructed glottis — by food, swelling, or a foreign body — can cause rapid suffocation requiring immediate action.
Grounding (Electrical)
In electrical injury scenarios, first aiders must ensure the power source is switched off and the scene is grounded before approaching the patient, to avoid becoming a victim themselves.
Gut
Abdominal or gut injuries can cause internal bleeding with few external signs. First aiders should lay the patient flat, keep them warm, and not give food or water while awaiting emergency services.
Gland
Injury to salivary glands, lymph nodes, or other glands in the neck or groin may indicate trauma or infection. Swollen glands alongside fever and wound redness can signal spreading infection.
Glue (Medical)
Medical tissue glue is an alternative to stitches for minor lacerations with clean edges. Some first aid kits include wound closure strips that function similarly to keep wound edges together.
Gingiva
Gum injuries from falls or impacts can bleed heavily due to the rich blood supply in the mouth. First aid involves applying gentle pressure with clean gauze and seeking dental assessment if teeth are damaged.
