Question

Quizplus · Accepted Answer

By placing the needle correctly in the angle between the xiphoid process and the left costal margin and directing the tip of the needle upward, backward, and to the left toward the left shoulder,the left pleura is not pierced. By passing the needle through the cardiac notches of the left lungs and pleura both these structures are avoided (see CD Fig. 4-5).
Entry of the needle into the pleural cavity produces a pneumothorax or hydropneumothorax.
