Suspected high-risk pulmonary embolism

Recognise possible pulmonary embolism with haemodynamic compromise and accelerate simultaneous resuscitation, diagnosis and escalation.

PAUSE BEFORE USING

This is an educational summary, not a point-of-care protocol. Follow current local emergency and medicines guidance and seek senior/specialist support.

FICTIONAL SCENARIO

A fictional 61-year-old becomes acutely breathless and syncopal six days after major surgery, with tachycardia, hypotension and clear lung fields.

01 · RECOGNISE

Frame the danger first.

  • Consider pulmonary embolism in otherwise unexplained acute dyspnoea, chest pain, syncope, hypoxaemia or haemodynamic compromise.
  • Establish recent surgery, immobility, cancer, previous venous thromboembolism, pregnancy and bleeding risk.
  • Do not allow a low oxygen requirement or non-specific ECG to provide false reassurance in an unstable presentation.
02 · FIRST PRIORITIES

Act, escalate, reassess.

  1. Call for senior, critical-care and relevant specialty help while beginning ABCDE resuscitation and monitoring.
  2. Use the current local pulmonary-embolism pathway to coordinate urgent imaging or bedside assessment appropriate to stability.
  3. Obtain essential investigations and assess anticoagulation/thrombolysis contraindications without delaying emergency decisions.
  4. Plan monitored transfer and reassess haemodynamics continuously.
03 · ESCALATE NOW IF

Red flags that change pace.

  • Persistent hypotension, shock, syncope or rising lactate
  • Severe hypoxaemia, altered consciousness or cardiac arrest
  • Evidence of right-heart strain with clinical deterioration
04 · COMMON ERRORS

What makes care less safe.

  • Using a routine low-risk diagnostic pathway in a shocked patient
  • Delaying specialist escalation until definitive imaging is available
  • Starting treatment without checking major bleeding risks and recent procedures
05 · STRUCTURED HANDOVER

Say the concern plainly.

Possible high-risk pulmonary embolism with [haemodynamic and respiratory findings], risk factors [summary] and bleeding risks [summary]. Diagnostic status is [state]; I need immediate senior/critical-care input for the reperfusion and anticoagulation plan.
