Operating on a pneumothorax

While watching a movie over spring break, a man fell down after being stabbed in the chest area (by running into a waiter). A person determined it was a pneumothorax and decided to treat it on the spot. She made a small incision into the chest and splashed vodka (they were next to a bar) on the wound. She then placed the pourer from the end of the bottle onto this incision to allow air to leave the chest. The chest deflated and began sticking to the lung again. Does this even come close to being realistic?
