I was meaning administering drugs using nebulization. So you put a mask over your nose/mouth and inhale for minutes the saline solution with the drugs you want to deliver in the aerosol form a machine is forming. The drugs are usually some topic corticoid, vasoconstrictor and mucus fluidifier. Some people have the machines at home to get a humidifying session before bed.
Those marine/saline baths are great, but I like better the ones that come into a soft plastic bottle with an olive in the tip closing completely the nostril, so you can apply all the pressure you need to get the nose clean.
The name is rather unfortunate
