Study Notes
ESI Triage
- Categorize emergency department clients according to the Emergency Severity Index (ESI)
- ESI incorporates illness severity and resource use to determine who to treat first
- Triage system: most critically ill are treated first
- ESI levels:
- ESI-1: Unstable ABCs, obvious life/organ threat, risk of dying, high resource intensity
- Examples: cardiac arrest, intubated trauma patient, overdose with bradypnea, severe respiratory distress
- ESI-2: Threatened ABCs, high-risk patient, high resource intensity
- Examples: chest pain from ischemia, multiple trauma unless responsive
- ESI-3: Stable ABCs, medium to high resource intensity
- Examples: abdominal pain, gynecological disorders unless in severe distress, hip fracture in older patient
- ESI-4: Stable ABCs, low resource intensity
- Examples: closed extremity trauma, simple laceration, cystitis
- ESI-5: Stable ABCs, need exam only
- Examples: cold symptoms, minor burn, prescription refill
- ESI-1: Unstable ABCs, obvious life/organ threat, risk of dying, high resource intensity
Primary Survey

- G: Get monitoring devices and give comfort
- Attach monitoring devices, give lab tests, and provide comfort measures
- A: Alertness and Airway
Secondary Survey
- Brief survey to address all injuries
- History and Head-to-Toe assessment:
- Listen to caregivers, assess mechanism of injury, signs, and symptoms
- Use MIST (Mechanism of injury, Injuries sustained, Signs and symptoms, Treatment before arrival)
- Use SAMPLE (Symptoms, Allergies, Medications, Past medical history, Last meal, Events)
- Full body assessment for abnormalities
- Head, neck, and face: check for extraocular movements, Battle sign, Racoon eyes
- Chest: inspect for respiratory distress
- Abdomen and Flanks: inspect for blunt trauma or intra-abdominal hemorrhage, perform FAST assessment

- Auscultate breath sounds, assess for decreased ventilation or adventitious sounds
- Monitor ventilator settings and alarms, tube placement, and cuff pressure
Mechanical Ventilation
- Complications associated with mechanical ventilation:
- Aspiration: treat by raising HOB 30 degrees, using Yankauer suction catheter or sterile use single catheter
- Alterations in gastric mobility: start bowel regimen
- Ventilator disconnection and malfunction: teach patient not to touch tube or remove tube, check secure tubes, and use alarms
- Infection: complication, normal defenses of the upper and lower respiratory systems are bypassed
- Sodium and water imbalance: treat based on deficiencies
- Alveolar hypotension: air leaking, not good settings on ET tube, sedation effects
- Barotrauma: too high air pressure ruptures alveoli
- Volutrauma: too large of volume causes rupture
- Vent-associated pneumonia: (due to no hand washing, contaminated equipment, adverse environment, or patient can't cough or clear secretions)

- Treatment: treat underlying cause, assess ability to breathe immediately, oxygen therapy, may need intubation and mechanical ventilation
- Medications: bronchodilators, corticosteroids, diuretics, iv antibiotics
- Nursing management: maintain patent airway, suctioning, absence of dyspnea, ensure they can effectively cough and clear secretions, chest physiotherapy, keep ABGs the same, may need non-invasive positive pressure ventilation, hydration### Acute Respiratory Distress Syndrome (ARDS)
- ARDS is a life-threatening condition that occurs when the lungs are injured, causing inflammation and flooding of the airspaces
- Causes of ARDS:
- Direct injury: pathogen in lungs, aspiration, virus, bacteria, drowning
