VPAP Adapt SV™

The right support at the right time—adapting breath-by-breath
VPAP Adapt SV™ is an adaptive servo-ventilator designed specifically to treat central sleep apnea (CSA) in all its forms, including complex and mixed sleep apnea.

Unlike conventional sleep-disordered breathing (SDB) therapies such as continuous positive airway pressure (CPAP), adaptive servo-ventilation:

• •  treats complex sleep apnea syndrome and central sleep apnea •  normalizes breathing, completely suppressing CSA and/or Cheyne-Stokes respiration (CSR)2,3 •  improves sleep architecture2 (the amount of time the patient spends in slow-wave and REM sleep increases).

  Peer-reviewed literature shows that adaptive servo-ventilation:

Support when it's needed

The adaptive servo-ventilation algorithm:

• •  adapts to the patient’s ventilatory needs on a breath-by-breath basis •  automatically calculates a target ventilation (90% of the patient's recent average ventilation •  adjusts the pressure support to achieve it.

Maximizing patient comfort and compliance

VPAP Adapt SV:

• •  ensures pressure support is synchronized to the patient's own recent breathing rate and flow pattern •  provides a constant, low level of pressure support.

BiPAP® autoSV™ with Encore® Pro SmartCard®
The BiPAP autoSV sleep therapy system is specifically designed to be the best choice for managing complicated sleep-disordered breathing patients. It combines a number of technologies to recognize and react to changing pressure needs, and it's clinically proven to treat obstructive, central and complex apneas and hypopneas, along with periodic breathing.

Obstructive Sleep Apnea (OSA)

OSA is the absence of airflow due to an occlusion in the upper airway that lasts at least 10 seconds in spite of continual effort to breathe. Severity is measured by the Apnea/Hypopnea Index (AHI) - the number of episodes per hour of sleep.

Central Sleep Apnea

Central Sleep Apnea is a pattern of breathing characterized by a normal deep inspiratory cycle interchanged with complete cessation of breathing. It is typically caused by problems with how the brain controls breathing rather than an occlusion of the airway.

Complex Sleep Apnea

Complex sleep apnea is a condition that occurs when a patient is identified as having OSA, but with the application of Continuous Positive Airway Pressure (CPAP) to eliminate the OSA, the patient develops Central Sleep Apnea. The cause of complex sleep apnea is not known at this time.

Periodic Breathing

Periodic breathing is defined as alternating periods of hyperventilation with waxing/waning tidal volume and periods of central hypopneas or apneas. There are many forms of periodic breathing, one of which is Cheyne-Stokes Respiration (CSR). CSR is characterized by a cyclic pattern of waxing and waning during periods of apnea, and deep, rapid breathing.
