Shock (Circulatory Shock)

Shock is a life-threatening state of acute circulatory failure in which cardiac output falls below the level required to meet tissue metabolic demands, resulting in widespread cellular hypoxia and organ dysfunction. It is not a single disease but a final common pathway arising from four major mechanisms: hypovolemic (volume loss), cardiogenic (pump failure), distributive (vasodilation), and obstructive (mechanical obstruction). All types, if untreated, progress through compensated, decompensated, and irreversible stages.

Recognition

  • Compensated (early): Anxiety, restlessness, tachycardia (HR >100), cool pale skin, slightly decreased urine output. Blood pressure may still be normal (compensatory mechanisms active)
  • Decompensated: Hypotension (SBP <90 mmHg), tachypnea, cold clammy skin, confusion, oliguria (very low urine output)
  • Irreversible: Profound hypotension, multi-organ failure, loss of consciousness, unresponsive to treatment
  • Type-specific signs:
  • Anaphylactic: urticaria, angioedema, bronchospasm, stridor
  • Neurogenic (high SCI): bradycardia with hypotension (absence of reflex tachycardia — unique)
  • Septic: fever, warm flushed skin early, then cold and clammy as compensation fails

MT Relevance

  • Absolute contraindication during any phase of active shock — call 911 immediately. Do not delay
  • Anaphylaxis prevention in the clinic: Screen thoroughly for latex allergy and product allergies. Use hypoallergenic oils. Include EpiPen protocol in your emergency plan
  • Post-shock recovery clients: Require medical clearance. Often have residual organ dysfunction, fatigue, and orthostatic hypotension. Position changes must be slow and supervised
  • SCI clients with neurogenic hypotension: Use conservative positioning. Avoid prolonged prone (drops blood pressure further). Keep sessions shorter. Know the client's established baseline blood pressure
  • Orthostatic hypotension in post-hospitalization clients: assist with all position changes. Have client sit 1-2 minutes before standing

Required Actions

  • Any suspected shock during a massage session: Call 911 immediately. Recognize compensatory signs (anxious client, pallor, tachycardia) before decompensation
  • Anaphylactic reaction during treatment: Stop treatment. Call 911. Assist with EpiPen if available. Position supine with legs elevated (unless breathing difficulty — then semi-reclined)
  • Do not attempt to treat or manage shock — this is exclusively a medical emergency

Key Takeaways

  • All types of shock are medical emergencies. Recognize compensatory signs (tachycardia, pallor, anxiety) before decompensation and call 911 immediately.
  • Massage is absolutely contraindicated during active shock.
  • Anaphylaxis can occur in the clinic from latex, massage oils, or client allergies — screen thoroughly and have an emergency protocol.
  • Post-recovery clients require medical clearance and gentle treatment focused on orthostatic safety.
  • Neurogenic shock (high SCI) uniquely presents with bradycardia and hypotension rather than compensatory tachycardia.
