Figures & data
Figure 1 Thoracic CT-scan, 7 mm thick slices.
Note: It shows a pattern of ground-glass appearance, without clear dependent location.
Figure 2 Differences in viscosity and osmolarity between several non-ionic low-osmolar contrast media at 20°C and blood at 37°C.
Figure 3 Poiseuilleߣs law of flow.
Notes: Poiseuille Law states that the flow (Q) of fluid is related to a number of factor: the viscosity (h) of the fluid, the pressure gradient across the tubing (∆p), and the lenght (L) and diameter (r) of the tubing. It can be successfully applied to air flow in lung alveoli.
Figure 4 StokesߝEinstein equation.
Note: Viscosity is inversely related to temperature.
Figure 5 The Starling relationship.
Notes: Starlingߣs law of the capillaries states that the movement of fluid between the capillaries and interstitial fluid is due to the net effect of all four of the pressures described.
