Overview
This lecture covers the assessment and management of medical emergencies encountered by EMTs, common infectious diseases, and patient assessment techniques in pre-hospital settings.
Types of Emergencies
- Medical emergencies result from illness or disease, while trauma emergencies are caused by physical injury.
- Common medical emergencies include respiratory, cardiovascular, neurological, gastrointestinal, urologic, endocrine, hematologic, immunologic, toxicological, behavioral, and gynecological conditions.
- Patients may present with both medical and traumatic problems simultaneously.
Patient Assessment
- Medical assessment focuses on the nature of illness (NOI), symptoms, and chief complaint.
- Do not let injuries distract from underlying medical issues; avoid tunnel vision.
- Remain professional and unbiased, even with uncooperative or frequent patients.
Scene Size-Up and Primary Assessment
- Ensure scene safety, use standard precautions, determine number of patients, and need for additional help.
- Identify NOI and consider spinal immobilization if indicated.
- Perform a rapid primary exam; assess airway, breathing, circulation (ABCs), and level of consciousness.
- Apply oxygen for patients with shock, breathing difficulties, or SpO2 < 94%.
History Taking
- Gather a thorough patient history using SAMPLE (Symptoms, Allergies, Medications, Past history, Last oral intake, Events).
- Use OPQRST (Onset, Provocation, Quality, Radiation, Severity, Time) to assess chief complaint.
- Bring patient medications to the hospital if possible.
Secondary Assessment
- Perform focused or full-body exams as needed, depending on patient’s consciousness and chief complaint.
- Assess vital signs: pulse, respirations, blood pressure, glucose, and pulse oximetry.
Reassessment and Transport
- Reassess patient’s status and vital signs (every 5 minutes if unstable, 15 if stable).
- Consider ALS backup and adjust treatments as needed.
- Transport rapidly if the patient is unstable, has altered mental status, airway/breathing/circulatory problems.
- Choose transport mode and destination based on patient needs and local resources.
Infectious Diseases Overview
- Assess and manage infectious diseases as other medical complaints, with an emphasis on standard precautions and exposure history.
- Notable diseases: Influenza, Herpes simplex, HIV/AIDS, Hepatitis (A, B, C), Meningitis, Tuberculosis (TB), Pertussis, MRSA, COVID-19, MERS, Ebola.
- Ask about recent travel and exposure history for travel-associated diseases.
Key Terms & Definitions
- Trauma Emergency — injury from physical force.
- Medical Emergency — illness or disease process requiring EMS.
- Nature of Illness (NOI) — the underlying medical cause of a patient’s complaint.
- Chief Complaint — main reason the patient called for help.
- SAMPLE — mnemonic for medical history questions.
- OPQRST — mnemonic for symptom assessment.
- Tunnel Vision — focusing on one issue, missing other important conditions.
