Study Notes
Emergency Airway Management
- Key techniques include head tilt/chin lift and jaw thrust for cervical spine protection.
- Assess gag reflex to determine the need for advanced airway management.
- Inspect back for potential injuries; remove the cause of injury immediately.
- Prevent hypothermia with warm blankets and intravenous (IV) fluid bolus.
Poisoning Response
- Contact poison control if poisoned; utilize lavage or activated charcoal for treatment.
- Nasogastric (NG) tube placement should be avoided in patients with facial or skull fractures.
- Oropharyngeal (OP) airway use is contraindicated if there is a present gag reflex.
- Endotracheal (ET) intubation may be necessary in advanced airway management.
Breathing Assessment
- Monitor rate, rhythm, and effort of breathing along with oxygen saturation (spO2 %) through auscultation.
- Follow the sequence of Airway, Breathing, Circulation, Disability, Exposure, Environment (ABCDE) for assessments.
Oxygen Delivery Methods
- Nasal Cannula (NC): delivers 1-6 liters of oxygen.

- High-Flow (HF) mask can provide up to 60 liters.
- Non-Rebreather (NR) mask: 10-15 liters at 100% oxygen.
Causes of Cardiac Arrest
- H's: Hypovolemia, hyper/hypokalemia, hypercapnia (increased H+), hypoxia (decreased O2), hypothermia (decreased temp), hypoglycemia (decreased sugar).
- T's: Toxins, cardiac tamponade, tension pneumothorax, thrombosis causing myocardial infarction (MI) or pulmonary embolism (PE).
Circulatory Assessment

- Check capillary refill time in the most distal extremities.
- Initiate CPR and defibrillation immediately if cardiac arrest occurs.
Disability and Neurological Assessment
- Assess level of consciousness (LOC) using the Glasgow Coma Scale.
- Rapid triage of conditions includes resuscitation for arrests, emergent treatment for life/limb-threatening conditions (e.g., shortness of breath, neurological emergencies, significant blood loss, angina), urgent care that requires timely attention, semi-urgent that can wait, and non-urgent cases that are not life-threatening.
Management of Snake Bites
- Do not apply ice, corticosteroids, or tourniquets in the management of snake bites.

Management of Snake Bites
- Do not apply ice, corticosteroids, or tourniquets in the management of snake bites.
Electrolytes and Fluid Balance
- Electrolytes: Essential for nerve function, muscle contraction, hydration, and pH balance.
-
Hypo and Hyper states:
- Hypo: Cells swell, conditions like hyponatremia (sodium <135) occur, leading to seizure precautions.
- Hyper: Cells shrink, associated with hypernatremia (sodium >145), causing restlessness and anxiety.
Fluid Solutions
- 0.45% NS (Hypotonic): Used for providing free water and treats hypernatremia.
- 0.9% NS (Isotonic): Commonly administered for fluid resuscitation in burns, blood loss, and dehydration.
- 3% NS (Hypertonic): Used cautiously in severe hyponatremia to pull water out of cells.
- D5W/NS: Considered isotonic with calories for energy.
Fluid Imbalance
-
Dehydration Signs:
- Increased BUN, hematocrit (Hct), specific gravity (SG), hemoglobin (Hgb) levels.
- Symptoms: Weak pulse, dry mucous membranes, poor skin turgor, amber urine, decreased urine output (UO).
-
Fluid Overload Signs:
- Decreased BUN, Hct, SG, Hgb levels, with symptoms like bounding pulse, increased blood pressure (BP).
Sodium (Na)
- Hypernatremia: Sodium >145, causing thirst, increased BP/HR, and seizure precautions.
- Hyponatremia: Sodium <135, fosters confusion, headache, N/V, and also requires seizure precautions.
Potassium (K)
-
Hyperkalemia: Levels >5.0. Monitoring essential due to cardiac risks, facilitating GI cramps, and fluctuations in kidney output.
- EKG changes: Tall T waves, prolonged PR interval, wide QRS, absent P wave.
- Hypokalemia: Levels <3.5. Strain on cardiac function comes with low BP, weak pulses, and increased GI motility.
Calcium (Ca)
- Hypercalcemia: Levels >10.5. Symptoms include bone pain, weakness, increased urine output, risk for kidney stones.
- Hypocalcemia: Levels <9.0, signaling potential seizure issues. Symptoms like numbness, tingling, cramps, and weakness appear.
Magnesium (Mg)
- Hypermagnesemia: Levels >2.1. Causes include low BP, decreased respiratory rate, and lethargy; associated with chronic kidney disease (CKD).
- Hypomagnesemia: Levels <1.3, characterized by increased DTRs, mental changes, and needs cardiac monitoring for possible arrhythmias.
Risk Factors and Management
- Furosemide Use: A diuretic linked to multiple electrolyte disturbances, essential for regulating fluid volume and preventing overload.
- Clinical Monitoring: Essential for maintaining electrolyte balances; EKG, vital signs, and urine output should be routinely assessed based on electrolyte levels.
Pneumothorax
- Pneumothorax refers to the presence of air in the pleural space.
- Tension pneumothorax causes tracheal deviation towards the unaffected side.
- Treatment for tension pneumothorax involves needle decompression.
- Risk factors include trauma, which can be life-threatening.
Signs and Symptoms
- Common symptoms include anxiety, pain during respiration, and respiratory distress.
- Typically characterized by decreased breath sounds and asymmetric respiratory rates.
Flail Chest
- Occurs due to rib fractures, typically from CPR or motor vehicle accidents (MVAs).
- Presents with paradoxical respiratory motion (inward movement of the chest during inspiration).
- Diagnosis is confirmed through a chest X-ray.
Chest Tube Management
- Chest tubes reinflate the lung by creating negative pressure.
- Systems often consist of three chambers: drainage, water seal, and suction.
- Initial drainage of 200 cc during the first hour, followed by 100 cc/hour is normal.
- Drainage color change: bright red indicates fresh blood, dark red indicates older blood.
Observations and Maintenance
- Continuous bubbling in the water seal chamber indicates an air leak.
- Tidaling reflects respiratory movements; rises and falls with inhalation and exhalation.
- Avoid clamping the chest tube to prevent complications.
Positioning and Care
- Position the head of the bed at 30-45 degrees to facilitate lung expansion.
- Keep the chest tube below the level of the chest to ensure proper drainage.
- Regular lung assessments every 4 hours are necessary.
- Encourage deep breathing and coughing to promote lung re-expansion.
Emergency Procedures
- If the chest tube does not drain, it may need to be replaced; notify healthcare provider.
- In case of tube dislodgement, cover the site with two layers of petroleum gauze to prevent pneumothorax.
- For a tube that has overturned, have the patient cough and exhale, then place the tube in sterile water.
Additional Care Instructions
- Maintain sterile technique, using iodine for cleaning as necessary.
- Regularly assess for subcutaneous emphysema and crepitus at the site.
- Avoid "milking" or "stripping" to prevent increased intrathoracic pressure.
- Perform incentive spirometry for 10 breaths while awake to encourage deep breathing.
- Ensure sterile water is available at the bedside for emergencies.
