Common Questions Across Every Knowledge Base
Search by word or filter by equipment category.
Manual Wheelchair Questions
What is the difference between a standard wheelchair and a lightweight wheelchair?
Lightweight wheelchairs generally use lighter frames and may offer more adjustability or easier propulsion and transport. Standard wheelchairs are often heavier and built for basic everyday or facility use.
What is the difference between a transport chair and a manual wheelchair?
A transport chair usually has small rear wheels and requires a caregiver to push it. A manual wheelchair may have large rear wheels that allow self-propulsion.
How do I measure for wheelchair seat width?
Seat width is generally based on seated hip width plus appropriate clearance. The exact amount depends on clothing, positioning needs and wheelchair design.
How do I measure wheelchair seat depth?
Seat depth should support the thighs without pressing behind the knees. Measure from the back of the pelvis to the knee crease and allow suitable clearance.
What wheelchair is easiest to put in a car?
Transport chairs and lightweight folding wheelchairs are often easier to load, but folded dimensions, weight, removable parts and caregiver lifting ability all matter.
When is a reclining wheelchair needed?
A reclining wheelchair may be considered when the user needs positional changes, cannot maintain upright posture or requires assistance with pressure, comfort or care.
Can a wheelchair be too wide?
Yes. Excess width can reduce postural support and make propulsion harder. Too little width can create pressure and discomfort.
How often should wheelchair brakes and tires be checked?
Check them regularly and whenever performance changes. Brakes must hold securely, and tires should remain properly inflated or undamaged.
Walker and Rollator Questions
What is the difference between a walker and a rollator?
A standard walker is lifted or advanced step by step. A rollator has wheels, brakes and often a seat, making it easier to move but requiring more balance and brake control.
Is a two-wheel walker safer than a four-wheel rollator?
It depends on the user. A two-wheel walker may provide more controlled support, while a rollator may suit users who can safely manage continuous movement and hand brakes.
How high should walker handles be?
Handles are commonly adjusted near wrist-crease height when standing upright with arms relaxed. Elbows should remain slightly bent.
Can someone sit on a rollator seat?
Only when the rollator is stable, the brakes are locked and the manufacturer permits seated use.
What wheel size is best for outdoor rollator use?
Larger wheels often roll more easily over uneven surfaces, but stability, width, brakes and user control are also important.
Can a rollator be used as a wheelchair?
Ordinary rollators are not wheelchairs and should not transport a seated user unless specifically designed and labeled for transport.
Patient Lift Questions
What is the difference between a patient lift and a sit-to-stand lift?
A passive patient lift can transfer a fully dependent user in a sling. A sit-to-stand lift requires the user to participate and meet weight-bearing and control requirements.
Can one caregiver operate a patient lift?
Some systems permit one trained caregiver, while facilities or care plans may require two. Follow manufacturer instructions and the transfer assessment.
How much room is needed to use a patient lift?
Room needs depend on base width, turning radius, furniture, bed clearance and transfer route. Measure the actual environment.
Can a patient lift pick someone up from the floor?
Some floor lifts can perform floor recovery when permitted and when the correct sling and technique are used.
What is the difference between hydraulic and electric patient lifts?
Hydraulic lifts use manual pumping, while electric lifts use a powered actuator and battery.
What determines patient lift weight capacity?
The complete system is limited by the lowest-rated component, including the lift, spreader bar, sling, scale and accessories.
Can a patient remain suspended in a lift?
No longer than necessary for the transfer. Patient lifts are transfer devices, not seating or holding systems.
How often should a patient lift be inspected?
Perform the manufacturer pre-use check before every transfer and follow the recommended preventive-maintenance schedule.
Patient Lift Sling Questions
Are patient lift slings universal?
No. The sling must match the user, lift, spreader bar, attachment style, transfer type and manufacturer compatibility instructions.
What is the difference between a loop sling and a clip sling?
Loop slings attach reinforced loops to approved hooks. Clip slings use engineered clips that lock onto a compatible cradle.
How do I choose the correct sling size?
Use the manufacturer sizing chart and consider weight, height, torso length, hip width, thigh size and body shape.
When is head support needed in a sling?
Head support may be needed when the user cannot reliably maintain head and neck position throughout the transfer.
Can a toileting sling be used for anyone?
No. Many toileting slings require sufficient head and trunk control.
Can a sling be left under the patient?
Only when the exact sling and care plan allow it. Seams, heat and moisture may increase skin risk.
When should a patient lift sling be replaced?
Remove it from service when fabric, seams, loops, clips, padding or labels are damaged, unreadable or uncertain.
Medical Mattress Questions
What is the difference between a hospital mattress and a regular mattress?
Medical mattresses are designed for adjustable bed frames, frequent care, moisture protection and specific pressure or positioning needs.
What is an alternating-pressure mattress?
It uses powered air cells that change inflation over time to redistribute pressure beneath the body.
What is low air loss therapy?
Low air loss systems move air through or around the support surface to help manage heat and moisture.
Can a medical mattress heal a pressure ulcer?
A mattress may support pressure management, but wound healing requires medical assessment, treatment, repositioning and management of risk factors.
What mattress is used for a bedridden patient?
The answer depends on mobility, skin risk, wounds, weight, moisture, pain and caregiver ability.
What does static mode do on an air mattress?
Static mode holds cells at a more uniform pressure instead of alternating.
What happens during a power failure?
Response depends on mattress design. Follow the manufacturer power-failure instructions.
How do I know if an air mattress is set correctly?
Use the manufacturer setup process, check inflation and verify that the user is not bottoming out.
Wheelchair Seat Cushion Questions
What is the best wheelchair cushion for pressure sores?
There is no single best cushion for every user. Skin risk, posture, sensation, transfer ability, body shape and wheelchair setup should guide selection.
What is the difference between foam, gel and air cushions?
Foam provides structure, gel adds immersion and air offers adjustable pressure redistribution but requires inflation monitoring.
What is an anti-thrust wheelchair cushion?
It uses a raised front contour and lower pelvic area to reduce forward sliding and improve pelvic containment.
How thick should a wheelchair cushion be?
Thickness depends on material, user weight, pressure needs, stability and wheelchair geometry.
What does bottoming out mean?
Bottoming out means there is insufficient support material between the body and the wheelchair seat base.
Can two wheelchair cushions be stacked?
Usually not unless specifically approved. Stacking changes height, stability and pressure distribution.
How often should a wheelchair cushion be replaced?
Replace or reassess it when foam remains compressed, gel leaks, air cells fail or posture and skin response worsen.
How much air belongs in an air wheelchair cushion?
Use the exact manufacturer setup method. Too much air may reduce immersion, while too little may cause bottoming out.
Homecare and Safety Questions
What equipment is commonly needed after hospital discharge?
Needs may include a hospital bed, mattress, wheelchair, walker, commode, patient lift, sling or bathroom-safety equipment.
How can a home be prepared for mobility equipment?
Measure doorways, halls, turning areas, bed clearance, bathroom access and floor surfaces. Remove trip hazards.
What are common warning signs of a pressure injury?
Warning signs may include persistent redness or discoloration, warmth, swelling, pain, blistering or skin breakdown.
How often should a person be repositioned?
Repositioning frequency must be individualized according to skin risk, support surface, mobility, tolerance and the care plan.
Who should perform a home mobility assessment?
Depending on the concern, an occupational therapist, physical therapist, seating specialist, nurse or physician may be involved.
When should equipment use stop immediately?
Stop when equipment is damaged, unstable, incompatible or causing pain, skin injury, unsafe posture or loss of control.
Can home medical equipment replace caregiver training?
No. Equipment improves safety only when it is appropriate, correctly set up and used by trained caregivers.
What should be checked before buying home medical equipment?
Review abilities, measurements, home environment, caregiver capacity, weight limits, compatibility, maintenance and return restrictions.
