Petroleum jelly creates a seal to prevent dessication as well as spacing the coverslip from the slide to prevent pressure on the slides contents.

Not only does it prevent air from getting in, it prevents water from the saline solution from evaporating. This keeps the slide wet longer and prolongs the experiment.

it seals the water in and keeps the air out.
