A dual-level oxygen device that automatically adjusts to treat obstructive sleep apnea and other respiratory issues during sleep. This means it automatically changes the airflow pressure level for both inhalation and exhalation. It is considered one of Resmed's top devices in its class and connects wirelessly to a mobile phone to monitor the user's condition. Original Price: 15500 SAR Selling Price: 4500 SAR Discount: 11000 SAR Includes a hand-held nebulizer (steam condenser/oxygen converter) that originally cost 550 SAR, all for the same requested price with no increase. How the device works: 1. The device pushes air through the tubes to the mask. 2. The mask allows pressurized air to enter the airway. 3. The humidifier adds moisture to the air you breathe. 4. A 90W power supply unit provides continuous power. 5. Filters are used to keep allergens away from the airflow. It treats individuals with obstructive sleep apnea, while the AirCurve 10 ASV treats central sleep apnea. It allows the expiratory pressure to be set at a low level of up to 4 cm H2O to enhance breathing comfort, regardless of how high the inspiratory pressure is set. This can be beneficial if you require higher pressure to treat sleep apnea. The integrated humidifier and optimized auto-adjusting climate control provide ideal breathing comfort. Easy-to-use controls and an intuitive interface make it simple to navigate settings and view your nightly sleep report. Device condition: Used, comes with its bag, indistinguishable from new, and works excellently. Brand: Resmed
