<I always assumed that force fields were different from force walls. In "City" Vila states that air can bleed through a force field, whereas the blister force wall mentioned by Slave in "Stardrive" would have to be airtight.>
Depends on how fast the air bleeds out. Vila and Kerril only had what they took with them, and it seemed to last a fair while. Slave's blister wall need only hold enough air for sufficient time to let Avon and Tarrant do the repairs.
