CPAP is the most effective treatment for sleep apnea and can potentially improve the patient’s sleep overnight; dramatically improving the quality of life for individuals afflicted with sleep apnea. ![BiLevel_Device](https://299691.hs-sites-na2.com/hubfs/DME/BiLevel_Device.jpg) #### BiPAP, or Bi-Level Positive Airway Pressure BiPAP, or Bi-Level Positive Airway Pressure, is another form of sleep therapy, which delivers alternating levels of a higher inspiratory pressure (IPAP) to keep the airway open as a patient breathes in, and a lower expiratory pressure (EPAP) allowing the patient to exhale easily. Thus, a BiPAP is much easier for users with neuromuscular disease to adapt to. The dual settings allow patients to get more air in and out of the lungs without the natural muscular effort needed to do so. ![auto_set_APAP_device](https://299691.hs-sites-na2.com/hubfs/DME/auto_set_APAP_device.png) #### APAP, or Auto-Set Postive Airway Pressure Auto titrating continuous positive airway pressure (**autoPAP**) machines are devices that are set at a variable pressure and adjust the pressure based on the patient's needs using an internal algorithm. The pressure is monitored and adjusted breath to breath to treat the obstruction.   ![servo_ventilation_PAP_device](https://299691.hs-sites-na2.com/hubfs/DME/servo_ventilation_PAP_device.jpg) #### Adaptive Servo-Ventillation (ASV) ASV is used primarily to treat [central sleep apnea](https://299691.hs-sites-na2.com/sleep-disorders). ASV provides positive expiratory airway pressure (EPAP) and inspiratory pressure support (IPAP), which is servocontrolled based on the detection of CSA. The device provides a fixed EPAP determined to eliminate obstructive sleep apnea. The ASV device changes the inspiratory pressure above the expiratory pressure as required to normalize patients’ ventilation. Pressure support may be set to a minimum of 0 and maximum pressure minus the EPAP (the MaxPS should equal MaxPressure – MinEPAP). With normal breathing, the device acts like fixed CPAP by providing minimal pressure support. When the device detects CSA, the device increases the pressure support above the expiratory pressure up to a maximum pressure, which can be set by the user. Additionally, an automatic, timed backup up rate is available. [Studies](http://emedicine.medscape.com/article/304967-treatment) demonstrate that ASV is superior to conventional positive airway pressure therapy for controlling the number of central sleep apneas, improving sleep architecture and daytime hypersomnolence, particularly for CSB-CSA, central sleep apnea syndrome, and complex sleep apnea.   ## Let us help you today! ### Sleepiness Quiz How likely are you to fall asleep during the day?
