Q

The patient should be rotated into an oblique position for the PA sternum for what reason

A

To prevent superimposition of the sternum with the vertebral column

38
Q

Why is anterior oblique preferred rather than posterior oblique

47
Q

Why should the patients shoulders be rotated forward in PA ribs

A

Move scapulae laterally away from ribs

48
Q

Breathing technique for upper ribs

A
