AirCurve VAuto, S, ST and ASV
The ResMed AirCurve 11 series represents the latest advancement in bilevel positive airway pressure (BiLevel PAP or BiPAP) therapy, offering tailored solutions for different types of sleep-disordered breathing. With four specialized models—VAuto, ASV, S, and ST—there’s a device designed for every patient’s needs. Here’s a clear guide to help you understand the differences and find the right AirCurve 11 model for your therapy.
AirCurve 11 VAuto: Auto-Adjusting for Obstructive Sleep Apnea (OSA)
The AirCurve 11 VAuto is engineered for people with obstructive sleep apnea (OSA), especially those who find traditional CPAP uncomfortable. VAuto uses auto-adjusting bilevel therapy, automatically changing pressure levels for both inhalation and exhalation to fit your breathing needs during the night.
- Best for: Obstructive sleep apnea (OSA) and CPAP-intolerant users
- Key feature: Automatically adapts pressures for optimal comfort
- Highlight: Three in four sleep apnea patients agree ResMed solutions help improve their quality of life.
AirCurve 11 S: Fixed Bilevel Therapy
The AirCurve 11 S model provides fixed pressure support, delivering separate, preset pressure levels for inhalation (IPAP) and exhalation (EPAP) as prescribed by your doctor. It does not automatically adjust during the night, making it suitable for patients who need consistent, stable bilevel therapy.
- Best for: OSA patients who need set pressure levels
- Key feature: Fixed IPAP and EPAP settings
- Highlight: Simple, reliable, and effective for patients with predictable breathing needs.
AirCurve 11 ST: Spontaneous/Timed Support for More Complex Needs
The AirCurve 11 ST is a Spontaneous/Timed (ST) bilevel device. In addition to delivering two fixed pressures, the ST model includes a backup rate feature that ensures you continue to receive breaths if your own breathing rate drops below a set minimum. This model is often prescribed for people with certain types of central sleep apnea, hypoventilation syndromes, or neuromuscular diseases.
- Best for: Central sleep apnea with low respiratory drive, neuromuscular disorders, chronic hypoventilation
- Key feature: Timed backup rate to deliver breaths if you don’t initiate them
- Highlight: Provides extra safety for patients who sometimes stop breathing on their own.
AirCurve 11 ASV: Adaptive Servo-Ventilation for Central and Complex Apneas
The AirCurve 11 ASV is designed for central sleep apnea (CSA), mixed apneas, and periodic breathing. Its adaptive servo-ventilation (ASV) technology monitors each breath, automatically providing extra support if it detects a pause in breathing or irregular pattern.
- Best for: Central sleep apnea (CSA), mixed apneas, Cheyne-Stokes respiration
- Key feature: Instantly adapts to your unique breathing patterns
- Highlight: Delivers a breath when you need it most, even during central events.
