Magnus' Bath Trach
This is a Fenestrated trach tube (See Types of Tracheostomy Tubes) which acts as a plug to prevent aspiration of water into the trach tube during baths or swimming. After this bathing trach tube has been installed they then cover the trach site with several layers of big thin pieces of glued plastic. "This works very well!" according to Magnus Dad.
Note: This procedure would not work for kids with upper airway obstruction and swimming with a tracheostomy is not recommended
