The mP_aw directly affects the P_aO₂by changing the lung volume.The position of the diaphragm on the chest radiograph correlates with lung expansion.Adequate lung expansion in an adult shows the ninth posterior rib above the level of the diaphragm in the midclavicular line.With this patient,the diaphragm is only at the seventh rib.Therefore,the mP_awneeds to be increased to improve lung expansion.
