Q

In terms of hydrostatic pressure, do you think that the effects will be the same on a patient in the vertical position (standing) as they are with a patient in a horizontal position (such as swimming)? Why or why not?

A

The hydrostatic pressure would be greater in the vertical position because the hydrostatic pressure increases with the depth of immersion. The horizontal position will have less hydrostatic pressure due to the fact that the limbs will be closer to the surface of the water.
