Acute pulmonary oedema may be the first presentation of heart failure or an exacerbation of existing known heart failure. It also may be secondary to another cause e.g. atrial fibrillation (AF), other tachycardias or bradycardia, critical cardiac ischaemia, valvular disease or renal artery stenosis.
For early or mild pulmonary oedema (crackles and upper lobe venous diversion): give high flow oxygen (5-10L/minute; also refer to Guidelines on Oxygen and Oximetry), loop diuretic (furosemide IV or oral 40mg) and review precipitating factors.
For severe pulmonary oedema follow advice below:
N.B. Once the acute episode is resolved and the patient is more stable consider long-term management below.
See the below flowchart for the management pathway in the diagnosis of heart failure.
Follow the links below for drug therapy and treatment options in HFrEF, HFmrEF and HFpEF respectively.
There are several classes of drug that should be stopped if the patient is at risk of dehydration due to acute illness (see table below).
Patients should be counselled to seek medical advice if they have diarrhoea or vomiting for more than 48 hours.
SGLT2 Inhibitors | Increased risk of euglycaemic DKA |
ACE Inhibitors | Increased risk of AKI due to reduced renal efferent vasoconstriction |
Diuretics | Increased risk of AKI |
Metformin | Increased risk of lactic acidosis |
ARBs | Increased risk of AKI |
NSAIDs | Increased risk of AKI due to reduced renal efferent vasoconstriction |
N.B. NSAIDS are contraindicated in all types of heart failure and should only be used in exceptional circumstances.
Vaccination and lifestyle advice should be provided to all heart failure patients.
Alcohol is contraindicated in those with alcoholic cardiomyopathy. Otherwise, can be taken in small quantities (1 or 2 units/day).
All patients with heart failure should be strongly advised not to smoke and should be offered smoking cessation advice and support.

When heart failure symptoms are stable, treatment optimised and appropriate self-management and social needs are met then patients will no longer receive planned HFLNS support. Any patient who develops worsening symptoms however, may re-access the service through their GP using the contact details above.
