Key Learning Points
1. Pulmonary artery catheters are an invasive monitoring device used to measure cardiac output, mixed venous oxygen saturations and intra-cardiac pressures.
2. They are useful in the diagnosis and assessment of critically unwell patients in the context of unexplained shock, pulmonary artery hypertension and severe cardiogenic shock, and in the perioperative management of patients with severe cardiopulmonary disease undergoing major surgery.
3. Pulmonary artery catheters are used as both a diagnostic and a monitoring tool and, in themselves, are not a therapeutic intervention.
4. Accurate interpretation of the data produced is essential to its use.
5. Complications are largely related to catheter insertion and advancement.
