CPAP machines are another kind of small, pressurized breathing device. BiPAP is normally the preferred option for people with COPD.
The main difference is that, while CPAP helps a person inhale by using one kind of pressure, BiPAP helps a person both inhale and exhale by using two different pressures. This means that exhaling is easier with BiPAP machines.
CPAP works by holding the airways open through continuous pressure, whether the individual is breathing in or out. This pressure stops the upper airways from collapsing, which makes breathing easier and helps to prevent oxygen levels from falling while the person is asleep.
Both BiPAP and CPAP machines can also be used to treat heart failure, which is a possible complication of COPD. This therapy lowers the amount of blood that is returned to the heart, meaning that it is under less strain.
Choosing a CPAP Machine
There are many CPAP machine manufacturers, each with several models offering different feature selections. Talk to your doctor about what features you will need for your unique obstructive sleep apnea diagnosis. Also consult your medical insurance to confirm which features they cover.
Listed below are some common features and options available for your CPAP machine:
Humidifier: A CPAP humidifier delivers moist air and may be less irritating to the nasal passages.
Data Logging: Data logging allows a doctor or technician to verify that the machine is working properly and the patient is getting the pressure required for proper treatment of sleep apnea. Some of these write the data to a removable card that can be taken to the doctor or sleep center for download, and others can transmit their data automatically through phone lines or a direct Internet connection.
Travel Pack: If you travel a lot, it is important to choose a CPAP that will travel well with you. Some have adjustable pressure for different altitudes, the ability to run on DC current from a car or boat battery or to run on foreign currents.
Advanced Air Pressure Settings: A more sophisticated CPAP device is called a BiPAP machine. This uses two different pressures: one when the sleeper is breathing in and one when breathing out.
CPAP Masks: Choosing the mask is a separate decision from selecting the machine and it is not uncommon to use a machine from one manufacturer and a mask from another.
Care and Maintenance
Although these devices are fairly maintenance-free, your CPAP machine should be inspected regularly to ensure proper function. Filters should be replaced often and the humidifier must be kept free of mold and algae. The hoses and masks of your CPAP machine should be inspected weekly for wear and buildup of particulate matter. The electrical connections should be checked for damage that could present a shock or fire hazard.
