The wide, clear display guides the user comfortable through the different ventilation modes and their adaptation to the individual needs of the patients. The powerful, performance optimized blower offers high flow reserves even at maximum therapy pressure and attracts attention by an extraordinary silent operation noise. So nothing is left to be desired even with a use at home. The internal high capacity rechargeable batteries provide energy reserves for intra- or extra-clinical transport, outdoor stays or for overcoming faults of the electrical power supply. Whether as a one tube or a two tube system, so whether as CARAT I pro or CARAT II pro, in invasive or non-invasive ventilation, this system is the always safe choice.
