Abstract

INTRODUCTION: Point-of-care ultrasonography (POCUS) has emerged as an important tool for examining critically ill patients. POCUS devices have become progressively smaller and more accessible, transforming medical practice, and reducing costs. One technological breakthrough was the development of ultraportable scanners with microchip technology, which utilize a probe connected to a smartphone or tablet and incorporate a mobile application that employs artificial intelligence to assist in the interpretation of acquired images. The aim of this study was to compare the accuracy of ultrasound microchip technology with traditional piezoelectric crystal ultrasonography. We analyzed 2 volume status parameters in intensive care unit (ICU) patients with acute kidney injury (AKI) who were receiving kidney replacement therapy (KRT). These parameters were the extravascular pulmonary water, using the lung B-lines; and the inferior vena cava collapsibility index (IVCi).
