ROHO

QUADTRO SELECT

Cushion Ination and Adjustment Guide

The QUADTRO SELECT

has four compartments of air cells. When the ISOFLO

Memory Control is open, the air ows freely between the compartments. When the

ISOFLO is closed, the air is “locked” within each compartment. The ination level of each compartment can be separately adjusted. This allows you to correct or

accommodate side-to-side and/or anterior-posterior asymmetries of the pelvis and upper legs. NOTE: Before adjusting the cushion for an asymmetry, you MUST

adjust the air ination level to the proper cushion ination setting as outlined below.

Adjustment Hand Check Results

1. Place the QUADTRO SELECT

cushion in the

wheelchair with the air cells facing up and the non-

skid surface of the cover facing down.

2. Before inating, you must open the ISOFLO Memory

Control so that all of the air cells inate. To open,

push green knob toward the unlocked position.

3. Slide the rubber nozzle of the hand pump over

the ination valve. Pinch the

nozzle, turn to open the

ination valve, and overinate

the air cells.

4. Remove the hand pump.

• If you can slightly move your ngertips: the cushion

is at the proper cushion ination setting (½” - 1” air

between the lowest bony prominence and the seat

surface) and no further adjustment required.

• If you can easily move your ngertips: there is too

much air between the lowest bony prominence and

the seat surface. Open the ination valve and slowly

release air until you can barely move your ngertips,

then close the ination valve.

• If you cannot move your ngertips at all: there is too

little/no air between the lowest bony prominence

and the seat surface. Open the ination valve and

slowly add air until you can slightly move your

ngertips, then close the ination valve.

The Permobil ROHO QUADTRO SELECT Cushion is a specialized air-cell cushion designed to provide pressure relief and postural support for individuals in wheelchairs. Its primary function is to distribute pressure evenly across the seating surface, reducing the risk of pressure injuries, while also offering adjustable support to accommodate or correct various postural asymmetries.

Function Description:

The cushion features four independent compartments of air cells. This unique design, controlled by an ISOFLO Memory Control, allows for precise adjustment of air inflation levels within each compartment. When the ISOFLO Memory Control is open (green knob pushed in), air flows freely between all compartments, allowing the cushion to conform to the user's shape and facilitating initial inflation. When the ISOFLO Memory Control is closed (red knob pushed in), air is "locked" within each compartment, maintaining the adjusted inflation levels and providing customized support. This independent adjustability is crucial for addressing side-to-side (lateral) and anterior-posterior (front-to-back) asymmetries of the pelvis and upper legs.

The cushion's core function revolves around a "hand check" method for determining the proper inflation level. This method involves sliding a hand between the cushion and the user's lowest bony prominence (typically the ischial tuberosities) to feel for a specific amount of air. The ideal inflation setting is when there is approximately ½" - 1" (1.5 cm - 2.5 cm) of air between the bony prominence and the seat surface, allowing fingertips to be moved slightly. This ensures adequate immersion and envelopment for pressure distribution without bottoming out or over-inflating.

Beyond basic pressure relief, the QUADTRO SELECT offers specific adjustment protocols for different postural needs:

Correcting Reducible (Flexible) Posterior Pelvic Tilt (Anterior-Posterior Asymmetry): This involves opening the ISOFLO Memory Control, positioning the pelvis at the back of the cushion in a neutral, upright position, and then using manual downward pressure on both sides of the pelvis. This action forces air into the front quadrants, creating a contour that discourages forward migration. The ISOFLO Memory Control is then closed to lock in this configuration, followed by a hand check to confirm proper inflation.
Correcting Reducible (Flexible) Pelvic Obliquity (Lateral Asymmetry): Similar to the posterior pelvic tilt correction, the ISOFLO Memory Control is opened, and the pelvis is positioned at the back of the cushion. The pelvis is then positioned in a neutral and upright posture by applying downward pressure on the higher side of the pelvis until it is level. This action forces more air into the quadrant under the lower side of the pelvis, helping to prevent tilting. The ISOFLO Memory Control is then closed, and a hand check is performed.
Accommodating Non-Reducible (Fixed) Postural Asymmetry: For individuals with fixed asymmetries, the goal is to support the pelvis in the best achievable posture and prevent further progression. The ISOFLO Memory Control is opened, and the individual is seated in their most upright and midline posture. The ISOFLO Memory Control is then closed to lock in this position, followed by a hand check to ensure proper inflation.

Important Technical Specifications:

While specific dimensions and weight capacities are not detailed in the provided manual, the core technical specification lies in its air-cell technology and the ISOFLO Memory Control system. The air cells are designed to conform to the user's body shape, providing dynamic pressure distribution. The ISOFLO Memory Control is a patented feature that allows for the independent adjustment and locking of air within the four compartments, making it a key differentiator for customized postural support. The recommended air gap for proper inflation is ½" - 1" (1.5 cm - 2.5 cm) between the lowest bony prominence and the seat surface.

Usage Features:

Ease of Inflation: The cushion is inflated using a hand pump, with a rubber nozzle that slides over the inflation valve. The valve is opened by pinching the nozzle and turning. Over-inflation is part of the initial setup process to ensure all air cells are fully expanded before adjustment.
ISOFLO Memory Control: This user-friendly control, with its green (open/unlocked) and red (closed/locked) knob positions, simplifies the process of adjusting and maintaining compartment inflation levels.
Hand Check Method: The manual provides clear, step-by-step instructions for performing a hand check, which is the primary method for ensuring correct inflation. This tactile feedback mechanism allows users or caregivers to accurately gauge the cushion's inflation level.
Postural Adjustment Protocols: The manual outlines distinct protocols for addressing different types of postural asymmetries (posterior pelvic tilt, pelvic obliquity, and fixed asymmetries), making the cushion highly adaptable to individual needs.
Non-Skid Surface: The cushion cover features a non-skid surface on the bottom, ensuring it stays securely in place in the wheelchair.

Maintenance Features:

Daily Inflation Check: The manual recommends checking the inflation level daily by performing a hand check. This routine check helps ensure consistent pressure relief and postural support.
Re-adjustment Schedule: Re-adjusting the inflation level is recommended only as needed, typically every 3-4 months, or if there are significant changes in the user's condition or seating requirements. This suggests a relatively stable inflation once properly set.
Cleaning: While not explicitly detailed in the provided excerpt, the nature of air-cell cushions typically involves wiping down the cushion and cover with mild soap and water. Regular cleaning helps maintain hygiene and extends the life of the product.
Durability: The ROHO brand is known for its durable air-cell technology, designed to withstand daily use. The instruction to overinflate initially suggests the material is robust enough to handle higher pressures during setup.

In summary, the Permobil ROHO QUADTRO SELECT Cushion is a sophisticated, adjustable air-cell seating solution that prioritizes both pressure injury prevention and dynamic postural support. Its four-compartment design, coupled with the ISOFLO Memory Control and the intuitive hand check method, empowers users and caregivers to achieve a highly customized and therapeutic seating environment.
