The Bongo RX Annual Pack is offered in sizes Small, Medium, Large & Extra Large. OBSTRCTUVE SLEEP APNOEA TREATMENT WITHOUT THE MASK No mask or machine required, the Bongo RX is a small, discreet device that can fit in the palm of your hand. The Bongo RX works by using EPAP (Expiratory Positive Airway Pressure) therapy to treat mild to moderate obstructive sleep apnOea. Once the device is inserted, upon inhalation, the valves in the cones open allowing you to breathe in normally. Upon exhalation, the valves close creating a more narrow outlet for the exhaled air to pass though which in turn creates the pressure that is needed to keep your airway open for the next inhalation. SIMPLE TO USE Using the Bongo RX is simple, just insert the device into the nostrils and breathe! On top of being simple to use, the Bongo RX is reusable and can be used for up to 90 days with proper cleaning.
