P O C U S CRITERIA

 Over the last 30 years, we have realized that POCUS is completely different from the routine radiological studies (Fig. 1). These differences include (1) POCUS is a Physiological study in which the shock status can be evaluated [6, 7], (2) it is an On spot clinical decision tool that helps in critical decision making in emergency situations within a very short time [8], (3) it is an extension of the Clinical examination and considered as the seventh sense of intra-abdominal inspection [9], (4) it is Unique with expanding indications to study different organs in a systematic approach at the same time [6], and finally, (5) it is Safe and repeatable and can be used exactly as a stethoscope in the hands of trained acute care physicians [6].
