Tension Pneumothorax
. Develops when air enters the pleural space, but a flap-valve mechanism prevents its escape . Intrapleural pressure rises, causing total lung collapse and a shift of the mediastinum to the opposite side, with subsequent impairment of venous return and a fall in cardiac output
208
The first step in managing shock in trauma is to
recognize its presence.

How is high pressure irrigation to wound done?
. High pressure irrigation (Normal Saline) . Minimum 100-300 ml with continued irrigation . At least 8 psi force to the wound (arrow) irrigation fluid dislodges foreign bodies, contaminants, and bacteria
254
After a wound the platelets do this
adhere to damaged endothelium and discharge adenosine diphosphate (ADP), promoting thrombocyte clumping, which dams the wound
