Breathlessness with Abnormal CXR
Last updated 13th September 2022
Initial Assessment
- Often need to start treatment before establishing a diagnosis if very sick.
- Give O2 titrate to appropriate SpO2 target, then check gases.
Most Likely Diagnoses
- Pulmonary oedema.
- Pneumonia, consider pneumocystis if immunocompromised.
- ARDS from a range of causes including aspiration, inhalation, lung haemorrhage, trauma.
- Intercurrent illness in pre-existing lung disease e.g.pulmonary fibrosis.
- Venous thrombo-embolism (rarely).
- Lymphangitis carcinomatosis (rarely).
Investigations
- Stethoscope not always helpful.
- CXR changes often difficult to interpret.
- Often have to rely on other tests for diagnosis e.g. ECG, WCC, CRP, BNP, TnT, microbiology, echo
X-Ray Features That Suggest Heart Failure
- Big heart with upper lobe vein diversion (upper lobe vein >3 mm in first interspace)
- Loss of costophrenic angle
- Kerley B lines (horizontal lines extending laterally to rib cage)
- Peri-bronchial cuffing
- Bilateral hilar shadowing
Management
- Pulmonary oedema – Frusemide and IV nitrates. Consider CPAP if response remains poor.
- Pneumonia – click here for link to Community Acquired Pneumonia Page
- Acute lung injury (ARDS) – likely to require ventilation.
- Venous thrombo-embolism – Fragmin.
- If diagnosis uncertain & patient ill then discuss with Senior: may have to consider antibiotic and diuretic (Frusicillin) or antibiotic, diuretic, nebuliser and steroid (Respoclear).
Consider ITU Assessment
- Discuss with Senior if RR >30/min or <10/min, requires > 50% oxygen to maintain target SpO2 or unable to maintain target, haemodynamic instability, multi-organ involvement.
