A hose hanger is a very important part of CPAP therapy. Most CPAP machine hoses are 6 feet in length and there will,in most cases,be an extra portion of the hose which will hang down. A hose hanger helps to control this extra hose,suspending it above the head of the user in different ways.
The most crucial function for a hose hanger is to lessen or prevent rainout which is caused by condensation inside the hose caused by the breathing process and humidity inside the room. This condensation forms water which collects in the hose and can interfere with cpap treatment by letting water into the mask.
This water problem can be alleviated by suspending the hose thus creating a dip in the hose for any water present to be collected. The hose should leave the machine,then start a downturn,before moving upward to the hanger. This will form a dip in the hose for any water. Water in a cpap hose can also lead to mildew and bacteria growth inside the hose so cleanliness is very important if there is any water inside your hose. Also,room temperature and humidity can play a role in rainout and by adjusting the temperature by just 2-3 degrees can help tremendously.
There are many forms of hose hangers out there,from manufactured hangers you can buy from many websites to any number of designs that a person can make themselves. Some mount to a wall while others are attached to a ceiling and hang down to the hose. Personally I use a hanger made from PVC pipe,1/2 inch,which can be found at most hardware stores. Mine stands 16 inches tall and has legs to slide underneath a mattress.
