EMT Basic Study Guide

Introduction to Emergency Care

Emergency Medical Technicians (EMTs) play a crucial role in the healthcare system, providing immediate medical care to patients in emergency situations before they reach a hospital. As an EMT Basic, you'll be trained to assess patients, administer basic life support, and transport patients safely.

Roles and Responsibilities

As an EMT Basic, your primary responsibilities include:

• Scene size-up and safety assessment
• Patient assessment and history taking
• Basic life support (CPR, AED, airway management)
• Bleeding control and shock management
• Fracture and spinal immobilization
• Emergency patient transportation
• Documentation and communication

Medical, Legal, and Ethical Issues

Understanding the legal and ethical framework of emergency medical services is crucial for EMTs. These guidelines protect both you and your patients.

Key Legal Concepts

• Duty to Act: The legal obligation to provide care when on duty and dispatched to an emergency.
• Standard of Care: The care that would be expected from a similarly trained EMT under similar circumstances.
• Negligence: Failure to provide the expected standard of care, resulting in harm to the patient.
• Good Samaritan Laws: Legal protection for those who voluntarily provide emergency medical care.
• Consent: Patients have the right to refuse treatment unless they are unable to make informed decisions (e.g., unconscious, mentally incapacitated, or under the influence of drugs/alcohol).

Ethical Principles

EMTs should follow these ethical principles:

• Beneficence: Acting in the patient's best interest
• Non-maleficence: Doing no harm
• Autonomy: Respecting the patient's right to make decisions
• Justice: Treating patients fairly and equitably

Anatomy and Physiology Basics

A solid understanding of human anatomy and physiology is essential for effective patient assessment and care.

Body Systems Overview

• Respiratory System: Responsible for oxygen exchange. Key structures include trachea, bronchi, and lungs.
• Cardiovascular System: Circulates blood throughout the body. Includes heart, arteries, veins, and capillaries.
• Nervous System: Controls body functions. Divided into central (brain and spinal cord) and peripheral systems.
• Skeletal System: Provides structure and protection. Important to understand for fracture assessment and spinal immobilization.

Vital Signs

Monitoring vital signs is crucial for assessing patient status:

Patient Assessment

Systematic patient assessment is a core skill for EMTs. The assessment process helps identify life threats and guide appropriate treatment.

Scene Size-Up

Before approaching the patient, conduct a scene size-up to ensure safety and gather important information:

• Scene safety (hazards, mechanism of injury, number of patients)
• Standard Precautions (PPE)
• Resource needs
• Initial impression

Primary Assessment

The primary assessment focuses on identifying and treating immediate life threats:

• Assess responsiveness
• Open airway and assess breathing
• Check circulation (pulse, bleeding, skin condition)
• Assess mental status (AVPU scale: Alert, Verbal, Pain, Unresponsive)

Secondary Assessment

After addressing life threats, perform a more detailed assessment:

• Physical examination (head-to-toe or focused assessment)
• Vital signs
• Obtain medical history using SAMPLE approach:
  • S - Signs/Symptoms
  • A - Allergies
  • M - Medications
  • P - Past medical history
  • L - Last oral intake
  • E - Events leading to present illness/injury

Medical Emergencies

EMT Basics must be prepared to recognize and manage various medical emergencies. While definitive treatment is often deferred to higher-level providers, prompt recognition and basic management can significantly improve patient outcomes.

Respiratory Emergencies

• COPD (Chronic Obstructive Pulmonary Disease): Chronic inflammatory lung disease including emphysema and chronic bronchitis.
• Asthma: Reversible airway obstruction characterized by wheezing.
• Pulmonary Embolism: Blockage in pulmonary arteries, often causing sudden chest pain and difficulty breathing.
• Hyperventilation: Rapid breathing leading to decreased carbon dioxide in blood, often triggered by anxiety.

Cardiovascular Emergencies

• Acute Coronary Syndrome (ACS): Includes angina and myocardial infarction (heart attack). Symptoms include chest pain, shortness of breath, nausea, and diaphoresis.
• Heart Failure: Inability of the heart to pump sufficient blood, causing fluid accumulation (especially in lungs).
• Cardiac Arrest: Sudden cessation of cardiac activity, requiring immediate CPR and defibrillation.

Neurological Emergencies

• Stroke: Interruption of blood flow to part of the brain. Remember FAST acronym:
  • F - Facial drooping
  • A - Arm weakness
  • S - Speech difficulties
  • T - Time to call emergency services
• Seizures: Abnormal electrical activity in the brain. Ensure airway protection and safety during seizure activity.

Trauma Management

Trauma injuries require prompt assessment and management to prevent further harm and stabilize the patient for transport.

Bleeding Control

Control bleeding using these methods in order:

1. Direct pressure
2. Pressure bandage
3. Tourniquet (for severe extremity bleeding when direct pressure fails)
4. Hemostatic agents

Shock Management

Shock is a state of inadequate tissue perfusion. Recognize signs including rapid/weak pulse, pale/cool skin, altered mental status, and decreased urine output. Management includes:

• Controlling bleeding
• Maintaining airway
• Providing oxygen
• Keeping patient warm
• Rapid transport

Orthopedic Injuries

For suspected fractures:

• Immobilize joints above and below the injury
• Check distal PMS (pulse, motor, sensation) before and after splinting
• Apply padding to immobilization devices
• Avoid over-tightening splints

Head and Spinal Injuries

For patients with suspected head or spinal injuries:

• Manual spinal immobilization immediately
• Apply cervical collar
• Secure patient to long backboard with straps and head blocks
• Monitor airway and breathing
• Transport promptly

Special Patient Populations

EMTs must adapt their assessment and treatment approaches for different patient populations.

Pediatric Patients

• Anatomic differences: larger heads, smaller airways, higher respiratory and heart rates
• Normal vital signs vary significantly with age
• Children compensate well initially but deteriorate rapidly
• Specialized equipment might be required for infants and children

Geriatric Patients

• Often have multiple chronic conditions and medications
• May present atypically (e.g., silent MI without chest pain)
• Decreased physiological reserve and compensatory mechanisms
• May have sensory and cognitive impairments affecting assessment

Pregnant Patients

• Physiological changes increase vulnerability to certain conditions
• Supine hypotensive syndrome can occur in later pregnancy
• Consider two patients (mother and fetus) in assessment and management
• Trauma in pregnancy requires specialized assessment and management

Emergency Operations

EMTs must understand the operational aspects of emergency medical services to function effectively in the field.

Incident Management System

• Structured approach for command, control, and coordination of emergency response
• Establishes clear chain of command and communication protocols
• Includes functions such as Command, Operations, Logistics, Planning, and Finance

Multiple Casualty Incidents

• Use triage systems (simple triage and rapid treatment - START)
• Assign patients priority categories: Immediate, Delayed, Minimal, Expectant
• Focus on greatest good for greatest number of patients
• Resource allocation based on triage priorities

Hazardous Materials

• Recognize potential hazmat situations
• Maintain safe distance - at least 100 feet from the scene
• Wait for specialized hazmat teams
• Remember hazmat placards and their meanings
