Refer to Design Step 1 for introductory information about this design example. Additional information is presented about the design assumptions, methodology, and criteria for the entire bridge, including the steel girder. Figure 3-1 Span Configuration. Figure 3-2 Superstructure Cross Section.
HYPOFLUORESCENCE Hypofluorescence may be caused by 1) blocked fluorescence, which is synonymous with negative fluorescence or transmission decrease, or 2) a vascular filling defect. Blocked fluorescence corresponds to the size, shape, and location of the blocking material seen ophthalmoscopically.
Common causes of hypoxemia include: Anemia; ARDS (Acute respiratory distress syndrome) Asthma; Congenital heart defects in children; Congenital heart disease in adults; COPD (chronic obstructive pulmonary disease) Emphysema; Interstitial lung disease; Medications, such as certain narcotics and anesthetics, that depress breathing; Pneumonia; Pneumothorax (collapsed lung)
