XT series is one of the smallest CPAP in the market. Its palm-sized and lightweight design lends itself well to travel. However, it delivers the same effective therapy as the larger machines, includes useful features like easy-to-adjust ramp settings, automatic altitude adjustment, leak compensation and data collection by SD card. And now, enhanced pressure stability and the clinically proven algorithm make the New XT series even more comfortable, with the introduction of the PVA pressure relief function.
