This allows for the detection of a pneumothorax with the absence of normal ‘lung-sliding’ and ‘comet-tail’ artifact (seen on the ultrasound screen). Compared with supine chest radiography , with CT or clinical course as the gold standard, bedside sonography has superior sensitivity (49–99% versus 27–75%), similar specificity (95 ...
In pneumothorax, air is present between the two layers of the pleura and lung sliding on ultrasound is therefore absent. The negative predictive value for lung sliding on ultrasound is reported as 99.2–100% – briefly, if lung sliding is present, a pneumothorax is effectively ruled out. [32]
Tension pneumothorax – the presence of which may be suspected due to rapidly deteriorating heart function, absent lung sounds throughout the thorax, and a barrel-shaped chest – is treated with an incision in the animal's chest to relieve the pressure, followed by insertion of a chest tube. [66]
A chest X-ray can rapidly identify a pneumothorax, seen as absence of lung markings. Ultrasound can show the lack of lung sliding. However, imaging should not delay treatment. [8] CT angiography is the standard of diagnosis of pulmonary embolism. Clots appear in the vasculature as filling defects. [18]
Ultrasound: Cardiac ultrasonography for any pericardial effusion that may be causing a cardiac tamponade, as well as any right ventricle dilatation that may indicate a massive pulmonary embolism. Bilateral lung ultrasonography to look for lung sliding and rule out a tension pneumothorax .
Left tension pneumothorax with a large, well-demarcated area devoid of lung markings with tracheal deviation and movement of the heart away from the affected side. Mediastinal shift is an abnormal movement of the mediastinal structures toward one side of the chest cavity .
Another doctor did an ultrasound, and still suspected that the pain was from working out. Had the doctors ordered a chest X-ray, they probably would have seen what was really going on—and it was ...
In humans, the left and right lungs are completely separated by the mediastinum, and there is no communication between their pleural cavities.Therefore, in cases of a unilateral pneumothorax, the contralateral lung will remain functioning normally unless there is a tension pneumothorax, which may shift the mediastinum and the trachea, kink the great vessels, and eventually collapse the ...
