10 posterior ribs
What would the instruction for respiration be for the following and why?
Lateral sternum
Lower ribs
PA oblique sternum
SC Joints
Lateral sternum-Deep insp. (to bring the chest out and prevent blur)
Lower ribs-Expiration (helps to bring up the diaphragm)
PA oblique sternum-Shallow breath (blur the lung markings)
SC Joints-Suspend respiration (prevent blur)
