- A Case Study by Wiley, physician specialized in Pulmonogy and Critical Care in Taiwan
Point of care ultrasound (POCUS) is now a game changing survey for patients in emergency department or critical care unit. The traditional ultrasound machines provide good quality of images but they are heavy and expensive. Especially in the era of COVID-19, a portable, easy-to-use and easily disinfected Ultrasound Machine is a must for physicians.
To choose a suitable device for POCUS, I did a review chart of the brands and portable devices in the market. As a physician, both convex probe for abdominal survey and linear probe for vessel evaluation are necessary. Sector probe could be replaced with convex probe in critical care condition so that is not so important. Wireless feature is necessary in the COVID-19 era. Price is also an issue if your hospital cannot buy one for you.
