Lung and pulmonary artery evaluation by echocardiography. A Normal lung ultrasound (LUS), represented by the presence of A lines. B LUS showing broad B-lines indicating pulmonary oedema. The black arrow shows mild pleural effusion and the red arrow shows a disruption in the pleural surface, usually caused by increased hydrostatic pressure in lungs. C Short axis view at the level of the greater vessels and D a modified angle long axis view used to assess pulmonary artery flow. The yellow filled square indicates the sample volume position to obtain the flow using pulse wave Doppler. E Pulmonary artery flow with the ejection and acceleration time represented (ET and AT, respectively). P, pleural line; L, liver. Ao, aorta; PA, pulmonary artery valve
