Summary: Point‐of‐care ultrasound has been embraced by anaesthetists as an invaluable tool for rapid diagnosis of haemodynamic instability, to ensure procedural safety and monitor response to treatments. Increasingly available, affordable and portable, with emerging evidence of improved patient outcomes, point‐of‐care ultrasound has become a valuable tool in the emergency setting. This state‐of‐the‐art review describes the feasibility of point‐of‐care ultrasound practice, training and maintenance of competence. It also describes the many uses of point‐of‐care ultrasound for the anaesthetist and describes the most salient point‐of‐care ultrasound views for anaesthetic emergencies including: undifferentiated shock; hypoxemia; and trauma. Procedural safety is also discussed in addition to relevant important governance aspects. Cardiac function should be assessed using the parasternal long axis, parasternal short basal/mid‐papillary/apical, apical four chamber and subcostal four chamber views, and should include a visual estimation of global left ventricular ejection fraction. Other cardiovascular conditions that can be identified using point‐of‐care ultrasound include: pericardial effusion; cardiac tamponade; and pulmonary embolism. Pulmonary emergency conditions that can be diagnosed using point‐of‐care ultrasound include pneumothorax; pleural effusion; and interstitial syndrome. The extended focused assessment with sonography for trauma examination may of value in patients who are hypotensive in order to identify intra‐abdominal haemorrhage, pneumothoraces and haemothoraces.
