Paramedicine is a fiercely competitive field discipline where a patient's life depends on a split-second judgment and precise treatment.
What is more important than anything else is a solid knowledge, repeated training, and a learning process that involves practical experience.

From the first exam for Introduction to Emergency Medicine, I wrote "This is the End: Dr. Yang's Reconstruction of Previous Exam Questions for Introduction to Emergency Medicine," striving to create a textbook that would not simply help students pass the exam, but would also closely connect exam preparation with the practical application of emergency medicine.
We hope this book will serve as a reliable guide, instilling confidence in students preparing for the national exam, and as a learning tool for emergency medical workers preparing for the firefighter and paramedic recruitment exam, enabling them to examine and strengthen their practical skills.

This textbook is based on the Introduction to Emergency Care and the frequently appearing questions from the National Emergency Medical Technician Examination. It has been restructured to reflect the latest emergency medical guidelines, clinical cases, and even trends in similar emergency medical exams.
By solving each problem with related background knowledge and thought processes, we enable readers to go beyond simple memorization and systematically understand the concepts and apply them to actual patient situations.
This will not only lead to an increase in the correct answer rate in the testing room, but also to accurate judgment and quick response in the field.
no see.

Additionally, this textbook summarizes and organizes theories that frequently appear on the exam, and it's structured so that students can identify and address their weaknesses through problem-solving.
Through repetitive learning, you will be able to fill in knowledge gaps, expand your clinical thinking through problem-solving processes, and further examine "what to do first and how to do it" when facing an emergency patient.
Beyond the short-term goal of passing the exam, this will serve as a foundation for growing into a life-saving emergency medical professional.

Emergency medicine is constantly changing with the times and environment.
But the unchanging truth is that the patient's safety and life are always at the center.
I hope this book will serve as a beacon of light for all those studying emergency medicine, helping them build true competency encompassing both knowledge and practice.

Finally, I would like to express my deepest gratitude to my colleagues, both senior and junior, who provided generous advice during the publication of this textbook, and to all emergency medical professionals who silently care for emergency patients in the field.
Your dedication and passion are the strength of emergency medicine, and I, too, want to learn and walk that path with you.

We hope that Dr. Yang's Introduction to Emergency Care, which will be reorganized into 2026, will serve as a reliable guide to achieving your dreams, helping you pass the exam and grow into a life-saving professional.
