6 INTENDED USE6 INTENDED USE
Intended use
The AtmosAir Velaris hybrid mattress system is intended for use by caregivers1in acute care,
long-term care and home care facilities, including private homes.
The hybrid mattress system is indicated for the prevention and management of pressure injuries. It
should be used as part of an individualised, comprehensive pressure injury protocol. This typically
includes: repositioning, nutritional support and skin care. The surface should be selected based on full
assessment of the patient needs.
The hybrid mattress system represents one aspect of a pressure injury management protocol. All other
aspects of care should be considered by the healthcare professional.
If existing wounds do not improve, or the patient’s condition changes the overall therapy regimen
should be reviewed by the healthcare professional.
As guidance the system when used in a non-powered reactive mode is indicated for patients that are
deemed to be ‘At Risk’ of a pressure injury. If the system is used in conjunction with the pump, the
SDWLHQWVZLWKDµKLJKHUULVNSUR¿OH¶PD\EHFRQVLGHUHG2
The Velaris Standard mattress, Plus and Plus Flex can all be used in conjunction with the Velaris pump
in order to step up therapy from reactive to active.
The Velaris Stretcher and Seat cushion are reactive only and cannot be used in conjunction with the
Velaris pump.
The above are guidelines only and should not replace clinical judgement.
The Standard mattress system is for patients within the weight range of 40 kg (90 lb) to 250 kg (550 lb).
Heavier patients weighing up to 454 kg (1000 lb) should use the Plus or Plus Flex (bariatric) mattress
system.
