The Iron Lung works by compressing and releasing the patient's lungs with air pressure which allows them to breathe normally, which you are unable to do with severe polio.
This clip starts where Part 1 ended... Hannah's neck rope is removed and she is sat back down in her chair. Brenda is put up against the post. Dr. Cupcakes goes back and forth. He adds some tape to Brenda, securing her to the post and then he gives Hannah some attention in the form of Black Tape, securing her to the chair. After Lots of red and black tape have been applied, he rips the nylon around their tits and binds all 4 of them with green tape... Very Festive! More red tape is used as he tapes Brenda's head to the post. She is completely helpless at this point and can not move an inch. Hannah can however, and the Good Dr. has a remedy. He ties a rope to the excess nylon on her hood and ties her head back. Some Very Heavy Duty clamps are added to their tits and then Dr. Cupcakes leaves them to mmmpph and struggle... I should say twitch, as there is not much room for struggle at this point. At the end of the clip I put in some behind the scenes footage of Hannah and Brenda being released.
