People who have had a laryngectomy are recommended to use a nebuliser. Some people find they need to nebulise quite often and others not at all. This device dispenses saline in a fine mist which is held over the stoma and breathed in to moisten the airway and loosen/thin mucus. You may be sent home from hospital with a large mains powered nebuliser similar to the blue one pictured.You can buy your own portable nebuliser which is a smaller handheld device that is battery operated and silent. Both forms of nebuliser use saline, this is usually provided in small ampules.
Never use normal water in a nebuliser, always use what you are instructed to by your team. It is also important not to use glass ampules as opening these can cause tiny shards of glass to be in the solution.
