This page covers 3 first aid words that start with X, ranging from “Xiphoid Process” to “X-Ray.” These terms cover anatomical landmarks, wound care materials, and medical imaging concepts that come up in emergency response and basic first aid training.

First aid words are the specific terms used to describe techniques, equipment, body parts, and procedures involved in giving emergency care to an injured or ill person. The field has roots going back centuries, but modern first aid was largely shaped in the 19th century by figures like Henry Dunant, whose experiences at the Battle of Solferino led to the founding of the Red Cross and the push to standardize emergency care worldwide.

Below you’ll find the table with Word, Definition, and Description.

Word: the exact term used in first aid contexts, so you can look up or recognize it in training materials and emergency guides.

First aid words

WordDefinition
Xiphoid ProcessThe small cartilaginous extension at the lower end of the sternum (breastbone)
XeroformA fine-mesh gauze impregnated with 3% bismuth tribromophenate in a petrolatum blend
X-RayElectromagnetic imaging that passes radiation through the body to reveal internal structures on film or a digital sensor

Descriptions

Xiphoid Process
A key anatomical landmark in first aid; rescuers locate the xiphoid process to correctly position hands during CPR chest compressions, avoiding pressure on this fragile tip.
Xeroform
Used as a non-adherent wound dressing in first aid and wound care; it keeps wounds moist, reduces bacterial contamination, and is gentle enough to remove without disturbing healing tissue.
X-Ray
While performed at medical facilities rather than on-scene, first aiders are trained to immobilize suspected fractures specifically so that subsequent X-ray imaging can confirm the injury without further displacement.
