Critical Assessment and Patient Care
Critical assessment in prehospital emergency care follows systematic protocols to evaluate patient conditions rapidly. EMS providers utilize standardized approaches to identify life-threatening conditions requiring immediate intervention.
Primary Survey Techniques
The primary survey employs the ABCDE method (Airway, Breathing, Circulation, Disability, Exposure) to identify immediate threats to life. Providers check airway patency by looking for obstructions breathing patterns through visual inspection chest rise rate circulation through pulse assessment. Scene safety evaluation precedes patient contact, with providers scanning for environmental hazards chemical exposures unstable structures. Initial assessments include level of consciousness response to verbal commands physical stimuli using the AVPU scale (Alert, Voice, Pain, Unresponsive).
Vital Signs Monitoring
Digital monitoring equipment captures essential vital signs including blood pressure heart rate respiratory rate oxygen saturation temperature. Continuous cardiac monitoring through 12-lead ECG devices detects rhythm abnormalities heart attacks other cardiovascular emergencies. Pulse oximetry devices track blood oxygen levels while capnography measures end-tidal CO2 indicating respiratory status. Documentation occurs at 5-15 minute intervals depending on patient stability transport duration.
Emergency Medical Procedures
Emergency procedures include advanced airway management through endotracheal intubation supraglottic devices bag-valve mask ventilation. Vascular access establishment occurs via intravenous peripheral lines intraosseous devices for medication fluid administration. Hemorrhage control involves direct pressure tourniquet application hemostatic agents for severe bleeding. Critical interventions include cardiac defibrillation synchronized cardioversion transcutaneous pacing for life-threatening arrhythmias.
Common Prehospital Emergencies
Prehospital emergency care providers encounter numerous time-critical medical situations that require immediate intervention. These emergencies demand specific protocols and rapid response to optimize patient outcomes.
Cardiac Events
Cardiac emergencies include acute myocardial infarctions, sudden cardiac arrest and life-threatening arrhythmias. EMS providers perform 12-lead ECG assessments to identify ST-elevation myocardial infarctions (STEMI) and initiate early hospital notification. Advanced cardiac life support protocols guide the administration of medications like nitroglycerin for chest pain and epinephrine during cardiac arrest. Early defibrillation within 3-5 minutes of cardiac arrest increases survival rates by 50-70%.
| Cardiac Emergency | Response Time Target | Survival Rate |
|---|---|---|
| STEMI | 90 minutes to PCI | 85% |
| Cardiac Arrest | 3-5 minutes to defib | 50-70% |
| Arrhythmias | 8-10 minutes | 90% |
Trauma Care
Trauma patients require rapid assessment using the MARCH algorithm (Massive hemorrhage, Airway, Respiration, Circulation, Head injury). EMS teams apply direct pressure or tourniquets to control severe bleeding and stabilize fractures using splinting devices. Multiple trauma protocols include spinal immobilization techniques and damage control resuscitation with permissive hypotension. Time-critical transportation decisions follow the “golden hour” principle for severe trauma cases.
| Trauma Type | Critical Interventions | Transport Window |
|---|---|---|
| Penetrating | Hemorrhage Control | 10 minutes |
| Blunt | Immobilization | 20 minutes |
| Head Injury | Airway Management | 15 minutes |
Respiratory Distress
Respiratory emergencies encompass bronchospasm, pulmonary edema and airway obstruction. Treatment protocols include oxygen therapy administration through nasal cannulas or non-rebreather masks based on saturation levels. Paramedics deliver nebulized medications for asthma attacks and manage advanced airways using endotracheal intubation or supraglottic devices. Continuous positive airway pressure (CPAP) provides non-invasive ventilatory support for specific conditions.
