AtmosAir Velaris accommodates a 'One Surface Strategy' as it can replace all but the most advanced automatic surfaces with one easy to use, flexible mattress system. When connected to the pump, AtmosAir Velaris transforms into an alternating therapy surface that can achieve full pressure offloading with AltoVac® technology. Without the pump attached, it provides reactive pressure redistribution through the ARM® (Air Redistribution Module) to maintain comfort and pressure levels in each air cell.
