 Point of care ultrasound(POCUS)is an ultrasound examination executed by the direct care-provider at the point of care, typically using compact equipment. In contrast to the comprehensive and detailed examinations by lab technicians, POCUS examinations should be simplified and goal-directed. Among the various applications of POCUS for perioperative care, airway and gastric ultrasound stand out in their significance with regard to anesthesia safety. Airway ultrasound can be particularly useful for tracheal intubation when capnography is unreliable, such as during resuscitation. Focused cardiac ultrasound is probably the most frequently applied ultrasound method in perioperative assessments, and it is also useful for observing cardiac contractility and movement, pericardial effusion, ventricular enlargement, etc. Lung ultrasound combined with cardiac ultrasound could be useful for pinpointing the cause of hypoxemia, via the bedside lung ultrasound in emergency(BLUE)protocol. Compared to chest X-rays, lung ultrasound has demonstrated higher sensitivity and specificity for diagnosing pneumothorax. Leg vascular ultrasound is both sensitive and specific for identifying deep vein thrombosis, and its routine application has the potential to avert life-threatening complications. Abdominal ultrasound can identify and quantify abdominal fluid accumulation. POCUS training involves didactic lectures and hands-on practice on human models. To promote the broader adoption of POCUS, endorsement by medical societies through the allocation of continuing education credits is recommended.
