Lung ultrasound has come in vogue during the COVID pandemic. LUS is simple to perform and can be readily done at the bedside. LUS performed well, together with a proper clinical history and physical examination, can help clinicians reach a diagnosis quickly before needing to perform more extensive investigations like HRCT scans of the lungs.
Indentification of B line artifacts in the lungs can mean pulmonary oedema (heart failure), interstitial syndrome (interstitial lung disease), infections (viruses or bacteria) and ARDS (acute respiratory distress syndrome).
LUS is a useful screening tool at the bedside in ward or emergency room. The ultrasound machine can also be used to scan other organs of the body (heart, blood vessels, liver, kidneys, etc) at the same sitting providing more useful clinical information.
