The main difference lies in how the air pressure is delivered.

AirSense (CPAP/APAP): Delivers one distinct pressure (or slight relief on exhalation) to keep the airway open.

AirCurve (BiLevel): Delivers two distinct pressures—a higher pressure when you inhale (IPAP) and a lower pressure when you exhale (EPAP).

The AirCurve 10 VAuto is specifically designed for patients who need higher pressure support or who find breathing out against standard CPAP pressure difficult. It automatically adjusts these pressures throughout the night to treat Obstructive Sleep Apnea while ensuring breathing feels natural.

Upgrading to a heated hose is highly recommended for BiLevel users, as higher air pressures can sometimes lead to increased dryness or condensation (rainout).

With a ClimateLineAir™ Heated Tube, you unlock the AirCurve 10’s full Climate Control capabilities. The device will automatically detect the room temperature and adjust the humidity output to ensure the air delivered to your mask is warm and moist, preventing rainout in the tube.

You may want one if you:

• Use high pressure settings (common with AirCurve)
• Experience dry mouth or nasal congestion
• Notice water droplets in your tube or mask
• Sleep in a cool room

You might not need one if you:

• Live in a very humid climate
• Don't use the humidifier feature
• Are already comfortable with your current humidity levels
  

For most BiLevel patients, the heated hose is a small investment that significantly improves therapy compliance and comfort.

Yes, the ResMed AirCurve 10 VAuto works with any standard CPAP or BiLevel mask using the standard 22mm connection. However, because BiLevel therapy often involves higher pressures, a secure seal is vital.

Important notes:

• Full Face Masks are often recommended for BiLevel users to handle higher pressures comfortably.
• ResMed masks (like the AirFit F20) are designed to handle the VAuto pressure changes effectively.
• Magnetic clips on masks require precautions for users with medical implants.
