How does nasal CPAP work?
Nasal CPAP "blows the airway open" to prevent airway collapse during sleep. The pressure setting must be determined for each patient during sleep, so you should not try to adjust the pressure setting on your own.
Because it works by increasing airway pressure, significant air leaks and air escape at the mouth can make them ineffective. Make sure your mask interface is properly placed before sleep, but excessive tightening may cause discomfort. Also, if a chinstrap is needed, be sure to wear it routinely!
Is it an oxygen machine?
No. It uses room air that is pressurized by a blower unit, much like a vacuum cleaner in reverse. Oxygen can be added, though, for patients who require it.
Does nasal CPAP cure sleep apnea?
No. They control sleep apnea, as long as they are used consistently: thus protecting patients from sleep apnea complications and symptoms
Does CPAP therapy remain effective over the years?
Yes.Unless other factors (such as sedating drugs or new illnesses) make your sleep apnea worse. Also, sleep apnea can worsen with both age and weight gain. With any change in your medical condition, you should consult your sleep specialist.
How good is nasal CPAP compared to other alternatives?
Much better: from the standpoint of both long-term effectiveness and safety. No other treatment, except a tracheostomy, is as effective at eliminating airway obstruction in sleep. The advantage of nasal CPAP is that it typically keeps the entire airway open, irrespective of where the collapse might have occurred. While children with sleep apnea due to large tonsils and adenoids often seem to respond to surgical treatment, results in adults have been disappointing. Nasal CPAP is safe and immediately effective, without operative risks or the need to wait for surgical healing before effectiveness can be determined.
What if I don't use my nasal CPAP?
Your sleep apnea will recur quickly, which in some patients can be dangerous.
Can I use it part-time?
NO. One common and potentially serious mistake would be to wake up toward the end of the night, remove your mask and allow yourself to fall asleep. Most of our REM sleep (the stage when most patients' sleep apnea reaches its greatest severity) occurs during the final hours of sleep, you will have removed it before you needed it more than ever.
Do I use nasal CPAP during naps?
Yes.
Can I travel with my nasal CPAP unit?
Yes. Traveling with your nasal CPAP unit is quite easy.
Are there contra-indications in using nasal CPAP?
YES. Some examples:
1. History of spontaneous pneumothorax, or large bullae ("blebs", similar to bubbles on a tire) that could rupture and cause lung collapse.
2. Individuals on high doses of steroids (ex. prednisone, Decadron®).
3. Severe inner ear problems.
4. Individuals with increase pressure in the brain (ex. hydrocephalus, pseudo tumor).
If you encounter problems, what steps should you take?
Refer to the troubleshooting guide. If no solution is found, call your homecare provider. Don't allow significant problems to persist, and don't allow yourself to go untreated and unable to use your equipment throughout sleep.
What about maintenance?
Clean your equipment regularly according to the manufacturer's recommendations. Broken, defective or worn equipment must be repaired or replaced immediately. Be sure to have your machine checked routinely and serviced once a year, even if it seems to be functioning well.
