How to do Lung Ultrasound to rule out Pneumothorax!<\/p>\n

1. Select your probe:
\nLinear probe, or vascular probe with low penetration and high frequency.<\/p>\n

\"\"<\/a>\ufeff\ufeff\ufeff\u00a0\"\"<\/a>
\n2. Technique:
\nTransducer should be in longitudinal position. It means your orientation marker should be toward the head of patient. Patient should be in supine position and probe should be in inter-coastal areas and you should scan at least 3 inter-coastal spaces. You can start from ant. axillary line toward lateral sternal border, or mid clavicle line, with this position you are looking at the pleura.<\/p>\n

\"\"<\/a><\/p>\n

Pleura is a bright whit line between two ribs. and if pleura moves with respiration , you should see a vertical line below the pleura. This line is an artifact (comet tail) and represents sliding of pleura(Fig.1). This artifact should be differentiate from B-Line. B line is a\u00a0 vertical lines that arises from the pleural line and continues to the edge of the screen.(Fig.2) B line will rule out pneumothorax. If we do not see any lung sliding and comet tail artifact, we should be suspicious for pneumothorax.<\/p>\n

\"\"<\/a><\/p>\n

If you do not see comet tail(reverberation) artifact and you would like to to have a confirmation test for that, you can proceed with M-Mode. you will set your M-Mode line in the middle of 2 ribs to go through pleural line. If you have a normal lung, M- Mode should show you some wavy, grainy, “sandy beach” appearance (seashore sign).<\/p>\n

\"\"<\/a><\/p>\n

If M-Mode show you no seashore sign, means there is no motion on pleura and there is no pleural sliding so you will see the following images = PTX<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

I do not want to confuse you but there are other lines in lung ultrasound such as A line, Z line , and E line. Just for your info, A lines are horizontal lines parallel to pleural line, with same bright echogenic feature.If there are A lines in the absence of lung sliding this can represent Pneumothorax<\/strong>. If A lines presents with lung sliding this\u00a0 could be Asthma<\/strong> or COPD<\/strong>.<\/p>\n
