Regarding POCUS in the cardiac field, a protocol called focus (focused) cardiac ultrasound (FoCUS) has been developed in Europe and the United States, is being used clinically, and an educational syllabus has been created. According to them, FoCUS is defined as a point-of-care cardiac ultrasound examination using standardized limited sections and protocols. FoCUS is primarily intended to be performed by non-cardiologists, and in order to avoid making mistakes in judgment, it is important to be familiar with its limitations and it is necessary to understand pathological conditions that can only be diagnosed using conventional comprehensive echocardiography. The Japanese Society of Echocardiography has edited this clinical guideline because we believe that FoCUS should be used effectively and appropriately in Japan, and that appropriate education is essential to popularize FoCUS in Japan. Furthermore, lung POCUS has recently come into clinical use. Lung POCUS is useful for the diagnosis and follow-up of heart failure when used in conjunction with FoCUS, and is especially useful in primary care where chest X-rays are not available.
