Point-of-care ultrasound in the global health and resource-limited setting

Point-of-care ultrasound (POCUS) is ultrasound that is used by the clinician at the bedside to answer immediate (often binary) clinical question and/or help guide procedures. It differs from what is often called consultative or ‘formal’ ultrasound in that it is performed at the bedside by the treating physician (images are not acquired by a technician nor interpreted by a radiologist or cardiologist) and the information from a POCUS study can be used immediately to assist in treatment decisions or guide a bedside procedure. POCUS has been growing rapidly and is now utilised by almost all medical and surgical specialities including critical care, emergency medicine, obs/gynae, anaesthesia, general medicine and many others.
