It is an interesting question - I have never read any sci-fi that describes a problem or change in sensation such as you suggest when the 'air lock' is pressurized and de-pressurized. The suit would experience much the same thig you describe going from 10M under water to the surface (one atmosphere). But there is nothing I have found in a search. | |

However, these astronauts do not seem to have any particular system to prevent the 'bends', although the recommended ascent rate is 60 feet per minute, so not a big issue in a 40 foot tank. I suspect they may slowly pressurize (and depressurize) the suit to the highest pressure expected. | |

The pressure inside the suit is continually adjusted to maintain a constant pressure, A routine procedure in neutral buoyancy tank simulations. In space, the pressure does not change. | |
