<qa>  What is the name of the study that will assess the efficacy of TUS inThis study will assess the efficacy of TUS in identifying extravascular lung water EVLW through the presence or absence of B-lines also known as comet tails on ultrasound; whilst also determining whether TUS can distinguish between other pulmonary pathologies that may cause both a similar ultrasonographic appearance and respiratory compromise. A TUS protocol will be tested and validated in a stable patient population, concurrently assessing patient and operator satisfaction with the tool. It is intended that the results of this study will inform a larger second-phase study of a modified TUS protocol in the acute clinical setting medical admissions unit - emergency department.
