A 75-year-old man wakes with sudden severe breathlessness and frothy pink sputum. He is diaphoretic, his respiratory rate is 36, his oxygen saturation is 84 per cent on room air, his blood pressure is 200/115, and he has bilateral crackles and a raised jugular venous pressure. Outline your immediate management. (10 marks)

Diagnosis: The flash cardiogenic pulmonary oedema — the sudden severe breathlessness, the frothy pink sputum, the hypoxia (the 84 per cent), the hypertensive crisis (the 200 over 115), and the bilateral crackles with the raised JVP.[1]
Management:
- The ABCDE, the sit upright.
- The high-flow oxygen and the CPAP early — the CPAP reduces the preload and the afterload, splints alveoli, improves oxygenation (the Cochrane confirms the benefit).
- The IV GTN infusion — the venodilatation and the arteriolar dilatation, the reduced preload and the afterload, the titrated to the controlled blood-pressure reduction (target gradual fall, not the precipitous).
- The IV furosemide — the diuresis and the venodilation.
- The treat-the-cause — the ECG and the troponin (the ischaemia and the MI), the echo (the function, the valve), the treat-the-trigger (the PCI, the rate or the rhythm control).
- The monitoring — the continuous oxygen saturation, the blood pressure, the respiratory rate, the urine output, the blood gas.
- The disposition — the high-dependency or the intensive care.
The caution: The morphine is the cautious (the respiratory depression, the hypotension). The vasodilator and the diuretic are the titrated to the response and the blood pressure.[1]
