Bi-level Pressure Devices
"VPAP" or "BPAP" (variable/bilevel positive airway pressure) provides two levels of pressure: inspiratory positive airway pressure (IPAP) and a lower expiratory positive airway pressure (EPAP) for easier exhalation. (Some people use the term BPAP to parallel the terms APAP and CPAP.) Often BPAP is incorrectly referred to as "BiPAP". BiPAP® is the name of a portable ventilator manufactured by Respironics Corporation; it is just one of many ventilators that can deliver BPAP.
* Doctors use CPAP to treat people who have moderate to severe sleep apnea.
* CPAP is the treatment of choice for people who have sleep apnea and co-morbidities such as coronary artery disease (CAD) or heart failure.
Overall, CPAP is effective for moderate and severe obstructive sleep apnea:
* Research shows that continuous positive airway pressure (CPAP) decreases daytime sleepiness, especially in those who have moderate to severe sleep apnea.
* Studies show that in people who have moderate to severe sleep apnea, nasal continuous positive airway pressure (NCPAP) lowers blood pressure during both the day and the night.
* CPAP is better than other non-surgical methods for treating obstructive sleep apnea.
* People with coronary artery disease who use CPAP for sleep apnea are less likely to have heart problems such as heart failure.
Most Common Problems that may occur with CPAP include:
* Dry nose and sore throat.
* Nasal congestion, runny nose, and sneezing.
* Irritation of the eyes and the skin on the face.
* Abdominal bloating.
* Leaks around the mask because it does not fit properly.
* Nosebleeds are a rare complication of CPAP.
Relieving side effects
You may be able to limit or stop some of the side effects:
* Your doctor may be able to adjust your CPAP to reduce or eliminate problems.
* Be sure the mask or nasal prongs fit you properly. Air should not leak around the mask.
* Use a humidifier or a corticosteroid nasal spray medicine to reduce nasal irritation.
