Assessing for anechoic (dark) fluid between the visceral and parietal pericardium suggestive of pericardial effusion.
Assessing for pleural effusion/haemothorax. Absence of lung sliding on respiration is also suggestive of pneumothorax.
Right Upper Quadrant
Assesses Morrison’s Pouch (Hepatorenal Recess) for dependent anechoic fluid suggestive of intra-abdominal bleeding
Left Upper Quadrant
Assesses Splenorenal Recess for dependent anechoic fluid suggestive of intra-abdominal bleeding
Assesses Pouch of Douglas (Rectouterine Pouch) or rectovesical pouch for anechoic fluid suggestive of pelvic bleeding
Radiological Signs of Pneumothorax
Visible visceral pleural edge with the absence of lung markings peripheral to this line
Peripheral space is lucent compared to the rest of the hemithorax
In cases of tension pneumothorax, you may see a mediastinal shift and tracheal deviation away from the lesion
Subcutaneous emphysema may be present
It May be associated with atelectasis
