Video 3: Medical Terminology Fundamentals — Building Your Clinical Vocabulary

Welcome to your first lesson in medical terminology. This might seem like an unusual way to start an EMT course, but I promise it is one of the most important investments you can make in your clinical career. Medical terminology is the language of healthcare. Every note you read, every report you write, every handoff you give, and every communication you have with nurses, physicians, and other providers will involve medical terms. If you do not speak the language, you will constantly be translat

Slideshow Outline

Slide 1
Medical Terminology
The Language of Healthcare / Built from Latin and Greek roots, prefixes, suffixes
Slide 2
How Terms Are Built
Prefix (beginning) + Root (middle) + Suffix (end) / Not all terms have all three / Example: tachy + cardi + a = tachycardia
Slide 3
Tachy- and Brady-
tachy- = fast (tachycardia, tachypnea) / brady- = slow (bradycardia, bradypnea)
Slide 4
Hyper- and Hypo-
hyper- = above, excessive (hypertension, hyperglycemia) / hypo- = below, deficient (hypotension, hypoglycemia)
Slide 5
Cardio-
Heart / Cardiac, cardiovascular, cardiorespiratory / One of the most common roots in EMS
Slide 6
Key Suffixes
-itis = inflammation / -emia = blood condition / -pnea = breathing / -algia = pain
Slide 7
Directional Terms (Part 1)
anterior = front / posterior = back / superior = toward head / inferior = toward feet
Slide 8
Directional Terms (Part 2)
medial = toward midline / lateral = away from midline / proximal = closer to trunk / distal = farther from trunk
Slide 9
Scenario Application
"Distal right tibia deformity with ecchymosis and swelling" / Specific, professional, precise / Compare to: "their leg is messed up near the ankle"
Slide 10
Why This Matters
Every report, every handoff, every conversation / Communication tools, not just academic words / Start using them now
Slide 11
Flashcard Commitment
Terminology cards in Module PREP-0 / These terms appear in every module / Investment now pays dividends throughout the course
