Managing Shock as an OFA Level 3 Attendant

By /

Table of Contents

Shock is a critical medical emergency where the body’s cells do not receive enough oxygen, leading to potentially life-threatening complications. Recognizing early signs and initiating immediate treatment is crucial for first aid attendants. This guide provides a structured approach to shock management.

Understanding Perfusion & Cellular Function

✅ Perfusion: The delivery of oxygen and nutrients to the body’s cells and removal of waste. ✅ Cellular Function Failure:

  • Cell function stops.

  • Cells die.

  • Tissue damage occurs.

  • Organ failure follows.

  • Death may result.

Causes of Shock

Shock in injured patients is most often caused by blood loss (hypovolemic shock), worsened by conditions like chest injuries.

Three Main Causes of Shock:

✅ Inadequate Blood Volume:

  • Blood loss from bleeding.

  • Fluid loss from burns, vomiting, diarrhea.

✅ Heart Damage (Cardiogenic Shock):

  • Heart attack (Myocardial infarction) impairs heart function.

✅ Other Factors:

  • Anaphylactic shock (severe allergic reaction).

  • Septic shock (infection-induced shock).

  • Neurogenic shock (spinal cord injury causing vasodilation).

Types of Shock & Symptoms

Hypovolemic Shock (Blood/Fluid Loss)

🚨 Causes: Bleeding, burns, severe vomiting/diarrhea. ✅ Symptoms:

  • Cool, pale, sweaty skin

  • Rapid heart rate & weak limb pulses

  • Altered consciousness

  • Rapid breathing & thirst

Cardiogenic Shock (Heart Failure)

🚨 Cause: Heart attack. ✅ Symptoms: Same as hypovolemic shock.

Anaphylactic Shock (Severe Allergy)

🚨 Cause: Widespread vasodilation & airway swelling. ✅ Symptoms:

  • Severe difficulty breathing

  • Swelling of the face, lips, or throat

  • Hives or rash

Septic Shock (Severe Infection)

🚨 Cause: Toxins from bacterial infection impair blood vessels. ✅ Symptoms:

  • Confusion (early sign)

  • Fever & flushed skin → Cool & pale skin later

  • Increased heart rate & breathing

Neurogenic Shock (Spinal Cord Injury)

🚨 Cause: Loss of nerve control over blood vessels. ✅ Symptoms:

  • Paralysis & numbness

  • Warm & dry skin in extremities

  • Lack of radial pulse

The Body’s Response to Shock

The body releases adrenaline to compensate, causing: ✅ Cool, pale, sweaty skin ✅ Increased heart rate ✅ Rapid breathing

General Principles of Shock Management

✅ Scene Safety & Assessment:

  • Ensure scene safety.

  • Activate workplace emergency response.

✅ Assess Level of Consciousness (LOC):

  • Attempt to communicate with the patient.

✅ Airway Management:

  • Keep the airway open & clear.

  • Provide assisted ventilation if needed.

✅ Breathing Assessment:

  • Check rate, rhythm, and quality of breathing.

✅ Circulation & Bleeding Control:

  • Check for signs of shock & major bleeding.

✅ Rapid Transport (RTC):

  • All shock patients are Rapid Transport Category.

  • Minimize delays—hospital care is essential.

✅ Ongoing Care:

  • Reassess ABCs every 5 minutes.

  • Avoid unnecessary movement.

  • Give nothing by mouth.

  • Prevent heat loss—cover the patient but do not apply external heat.

Special Considerations

Athletes & Shock

⚠ Trained athletes may not show early signs of shock due to conditioned hearts. ⚠ Watch closely for delayed deterioration.

Cardiac Patients & Shock

⚠ Shock symptoms may be masked due to heart medications. ⚠ Prioritize rapid transport.

Key Signs & Symptoms of Shock

✅ Early Signs:

  • Cool, pale, sweaty skin. ✅ Other Indicators:

  • Cyanosis (blue lips/skin).

  • Distended neck veins.

Shock & Brain Dysfunction

🚨 Low blood pressure can impair brain function. ✅ Symptoms progress from lethargy & weakness → decreased consciousness. ✅ In major trauma cases, brain dysfunction can be caused by:

  • Shock

  • Head injury

  • Both conditions combined

Key Actions for First Aid Attendants

✅ Early Recognition – Stay alert to shock symptoms. ✅ Control Bleeding – Stop blood loss immediately. ✅ Maintain Airway & Breathing – Ensure oxygen supply. ✅ Administer Oxygen – Use high-flow oxygen. ✅ Keep the Patient Still & Supine – Minimize movement. ✅ Prevent Heat Loss – Cover patient, avoid external heat sources. ✅ Arrange for Rapid Transport – Minimize delays. ✅ Continuous Monitoring – Reassess ABCs every 5 minutes. ✅ Document Findings – Complete first aid records.
