What is CPAP?
The tern CPAP stands for Countinuous Positive Airway Pressure. CPAP Machines are small and lighweight units which blow a continuous colume of air into a person’s airway usinga facial mask with a special tube through which the air is blown onto the nasal passages. This mask, which is worn at night while sleeping, prevents the airways fro collapsing while the individual is sleeping. This process allows the Mechanics of Ventilation to function throughout the night.
CPAP Units Have Different Features
Most units come with a “ramping” mode, which allows the CPAP unit’s pressure to be reduced from the prescribed pressure. This will help a CPAP user fall asleep under a lower pressure than was ordered by the physician.
Humidification is a very important feature on a CPAP unit. A humidifier on a CPAP unit allows the air being blown onto the airway to be moistened before it reaches the airway. Without a humidifier, the dry air will cause the nasal mucosa (the lining of the nasal passage and airway) to dry out, crack and bleed. Humidifiers can be cool or heated.
Every person with sleep apnea has special needs and there are many different types of masks or facial appliances on the market. The mask must be a good fit and seal without being too tight or too uncomfortable.
Some of the newer units on the market have data cards which record information as you sleep. This information can be valuable to your physician and changes to your treatment plan can be made without the usual office visit. These changes may involve increasing or decreasing your pressure level , as your physician may want to add supplemental oxygen to your system. Data pards also provide a compliance record required by some insurance companies.
Side Effects
Because an ill-fitting mask can cause facial abrasions and sores where the mask or straps come in contact with the face, certain adjustments should be able to the mask and headgear to assure a secure fit. A mask that is too large or too small may cause leaking and keep a person awake at night. These leaks also may be blowing into the eyes causing dryness or irritation.
Another common side effect with CPAP use is the feeling of nasal congestion. The is due to the volume of air being blown into the nasal passages and causing them to swell. In essence, the airways are being invaded, and the reaction is to swell. This is a temporary side effect which will normally resolve itself. Sore throats or a dry mouth may also occur. This is most commonly caused by the mouth coming open at night when a person falls asleep. This can be corrected by the use of a chin strap to hold the lower jaw closed, or simply by opting for a full-face mask which covers the mouth and nose.
In conclusion, use your CPAP and rest your heart and mind on your way to better health!
