CPAP machines are the best known treatment for sleep apnoea. They are powered by mains electricity and provide a flow of pressurised air to the windpipe via a length of plastic tubing and a face or nasal mask. The air holds the windpipe open, preventing blockages and allowing normal breathing to continue.
CPAP machines are not without fault and many patients report finding them uncomfortable, noisy and difficult to get accustomed to but they do work. When lifestyle changes and weight loss don’t remove the problem, doctors turn to CPAP machines.
The devices should be prescribed by a doctor, who will calculate the appropriate pressure through a sleep study. The device is supplied directly by the manufacturer. CPAP machines must be cleaned regularly to prevent dust getting into them and into the patient’s throat.
Make sure you clean the face mask and nasal pillows every day. This needs only warm soapy water and a good rinse. They should be left to dry completely before being returned to the machines.
A damp cloth should be used once a week to thoroughly clean the unit. Make sure that it is not connected to the mains when you do this. Also clean the filter at the back of the machine carefully once a week. It will need to be replaced annually.
Humidifiers have been fitted to many modern CPAP machines to prevent the throat from drying out. The humidifier should be cleaned each week.
Each year the machine should be returned to the manufacturer, local hospital or stockist to be serviced. This ensures the machine is set to the right pressure and that it is in good working order.
