Official Title
Lung Ultrasound for Assessment of Patients With Moderate to Severe Covid-19
Brief Summary

This observational study will describe lung ultrasound (LUS) findings over time in hospitalized patients with moderate to severe Covid-19 lung disease. Our primary aim is to investigate if lung ultrasound can identify and/or predict patients requiring mechanical ventilation. Another aim is to describe LUS findings associated with clinical findings and patient condition.

Detailed Description

Study patients with moderate to severe Covid-19 infection will be screened with lung
ultrasound daily. Lung ultrasound will be assessed by LUS-score for acute respiratory
distress syndrome (ARDS) (0-36 points, Bouhemad 2015). Findings of B-line artifacts and
consolidations will be noted. In addition to LUS, clinical parameters from physical
examination and laboratory tests will be collected. Participants wil be followed until either
admission to intensive care unit (ICU) for mechanical ventilation or until clinical
improvement. A group of patients with mild Covid-19 infection will be recruited and screened
once as reference.

Apart from assessment with LUS, patients are managed according to routine care.
