1.1 ). In patients who are unable to stand, anteroposterior (AP) upright or supine projections offer alternative but considerably less satisfactory views. The AP projection is of inferior quality because of the shorter focal-detector distance, the greater magnification of the heart, and the ...
The additional impact of obesity on moderate or severe Osteogenesis Imperfecta seemed to determine: (1) a higher incidence of obstructive sleep apnoea syndrome; (2) hypoventilation in the seated position; and (3) a higher incidence of paradoxical breathing while lying supine....

the abdominal pressure generated by the diaphragmatic contraction influences mainly the lower ribs. The ribcage then elevates and expands where it is apposed to the diaphragm. This is necessary in order to maintain total lung volume. The infrasternal angle can increase from 68.5˚ to 103.5...
