Product information

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.

The right support at the right time—adapting breath-by-breath
Unlike conventional SDB therapies such as 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:

  • Enhances quality of life for patients with CSA3,4.

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
  • Enables AHI tracking.

Enhanced VPAP Adapt SV

  • Natural comfort of Easy-Breathe technology
  • 89% quieter than the competition (based on internal sound comparison testing)
  • Efficacy tracking with AHI
  • Increased pressure ranges (see chart below)

*Advanced menu
The VPAP Adapt SV will automatically limit to ensure that:
- MAX PS minus MIN PS is greater than or equal to 5 at all times
- EEP + MAX PS will not exceed 25 cm H2O
To satisfy these limits:
1. Setting EEP automatically adjusts MIN PS then MAX PS
2. Setting MIN PS automatically adjusts MAX PS
