Lung ultrasound in covid-19
Coronavirus-19 (Covid19) is a respiratory virus that can trigger severe respiratory failure and acute lung injury. The typical symptoms of Covid19 are non-specific to respiratory illnesses and chest radiography lacks sensitivity and specificity. Computed tomography (CT) is much more sensitive to the detection of this virus, but also poses a number of concerns: availability, patient transport, disinfection, cost, radiation, and patient stability. Lung ultrasound (LUS) has emerged as a possible attractive alternative to CT as it is fast, portable, relatively inexpensive, and can be done at the point-of-care. While demonstrating potential findings consistent with Covid19 lung involvement (1), LUS may have prognostic value in predicting the progression of respiratory failure (2 ).
