If it is easier, here are the individual pages with the updated corrected text blocks.
Page 2:
Scan through placenta from edge to edge. Rotate probe 90˚, rescan. Determine where maximal cross section is. Keep probe perpendicular to base of placenta.
Page 3:
For the ideal image, freeze a perpendicular cross section at the maximal width of placenta.
Page 4:
Take Width measurements from the tip edge to the opposite tip edge. Leave width line in place.
Page 5:
Locate top apex point of maternal surface of placenta. Fix a point. Create a line going towards width line. Move Height line along Width line until Height line is perpendicular to Width line. Fix second point of Height line.
Page 6:
Fix a new point on top of apex point created for Height line. Move along Height line until fetal surface of placenta is reached. Fix second point of Thickness. Thickness is always equal to or less than Height.
Page 7:
Enter Width, Height and Thickness data into EPV calculator.
Page 8:
Use week and day wheels to enter correct gestational age. Click Done in upper right corner to enter data point.
Page 9:
EPV is plotted against GA. As the pregnancy progresses, each additional EPV data point is added to this graph.
Page 10:
If EPV value is either below the 10th %ile or above 90th %ile, repeat with as new cross section of the placenta to confirm value. Add new data into EPV calculator, enter same GA, click Done. Both data points are displayed. You can repeat EPV measurements at the same GA as many times as you wish.
