Acute RV failure with hypotension, syncope, hypoxaemia, rising lactate or suspected PE/RV infarction requires immediate ABCDE care, senior cardiology/critical-care help, urgent echo and cause-specific reperfusion or support.
Synopsis
Recognise systemic venous congestion and acute RV shock, identify the cause and balance preload, afterload and contractility without reflex fluid or vasodilator harm.
Right-sided HF causes raised systemic venous pressure: raised JVP, peripheral oedema, ascites, hepatomegaly, early satiety and congestive renal/liver dysfunction.
Common drivers are left-sided HF, pulmonary hypertension or lung disease, acute PE, RV infarction, tricuspid/pulmonary valve disease, cardiomyopathy and constrictive pericardial disease.
Acute RV failure can present with shock and clear lungs; do not exclude cardiac shock because crackles are absent.
Key red flags
Acute RV shock
Hypotension, cool peripheries, oliguria, confusion and raised JVP, sometimes with clear lungs; rising lactate signals worsening output.
Investigation priorities
01
12-lead ECG including right-sided leads when RV infarction suspectedFirst step
Identify inferior/RV MI, RV strain, AF or other arrhythmia.
Management branches
First-lineAcute RV failure
Raised JVP with hypoperfusion, hypoxaemia or shock
Start ABCDE, cardiac monitoring, blood gas/lactate and urgent echo; call cardiology and critical care.
Treat hypoxia, acidosis and the driver: activate ACS reperfusion for RV infarct or NICE PE diagnosis/reperfusion for suspected high-risk PE.
Key medicines
FurosemideFor chronic oedema a common oral start is 20–40 mg in the morning; acute congestion commonly starts 20–40 mg IV if loop-naive, with higher response-led IV dosing when already exposed.
NoradrenalineThe cited ready-to-use SmPC, licensed for adults weighing over 50 kg, starts noradrenaline base at 0.05–0.15 micrograms/kg/min by central IV infusion pump, titrated in critical care to adequate MAP/perfusion.
National guidance is shown before implementation-dependent detail. Typical adult dose examples remain subject to patient factors, contraindications and the live BNF or specialist protocol. Source check completed 27 Aug 2026; clinical approval remains outstanding.
