If they have time, astronauts and cosmonauts will look to plug the leak or close the hatch to the leaking section of the station. (That is how they dealt with a minor leak in the station’s PrK module for a number of years, and it basically worked.)

Astronauts could suffer hypoxia, oxygen deprivation so debilitating they could become delirious. It will be a heart-wrenching call, but if nothing else can be done, the crew will need to go to their crew vehicles and leave the ISS.
