A fictional 76-year-old with hypertension develops abrupt severe breathlessness, widespread crackles, cool peripheries and falling oxygen saturation.
Frame the danger first.
- Treat marked respiratory distress, hypoxaemia or poor perfusion as time-critical while assessing the cause.
- Look for acute coronary syndrome, arrhythmia, hypertensive emergency, valve disease, infection and treatment non-adherence as precipitants.
- Use bedside findings, ECG, imaging and blood tests together; no single finding establishes the diagnosis in every patient.
Act, escalate, reassess.
- Call for senior and specialist help, begin ABCDE assessment, sit the patient appropriately and monitor continuously.
- Follow the current local acute-heart-failure pathway for oxygen, ventilatory support, diuresis and selected vasodilator treatment.
- Investigate and treat the precipitant in parallel without delaying physiological support.
- Reassess work of breathing, oxygenation, blood pressure, urine output and response after every intervention.
Red flags that change pace.
- Exhaustion, altered consciousness, severe hypoxaemia or impending ventilatory failure
- Shock, myocardial ischaemia, dangerous arrhythmia or acute valve catastrophe
- Poor response to initial treatment or need for non-invasive/invasive ventilation
What makes care less safe.
- Giving routine high-concentration oxygen without a clinical indication
- Treating congestion without searching for the precipitating emergency
- Persisting with ward-level care despite worsening respiratory effort or perfusion
Say the concern plainly.
Suspected acute pulmonary oedema with [oxygenation/work of breathing], blood pressure [result] and perfusion [summary]. Likely precipitant is [known/uncertain]; treatment response is [summary]. I need urgent cardiology/critical-care input for [ongoing threat].
