A Low Air Loss Mattress vs Alternating Pressure Mattress comparison can feel overwhelming. Perhaps you’re concerned about pressure ulcers or seeking relief. You may have already read confusing advice online. This article is here for answers.
In this guide, we break down Low Air Loss vs Alternating Pressure mattresses, explain when hybrids are best, and give you a step-by-step selection guide. We also summarize the clinical evidence and guidelines, so you can make an informed choice for yourself or a loved one.
Let’s start by understanding why your mattress choice is crucial for your health and well-being.
Why Mattress Choice Matters
When patients lie in one position too long, skin and tissue lose blood supply and break down. This causes pressure injuries (bedsores), a common but serious problem.
- In the U.S., 1–3 million people develop pressure injuries annually.
- Care costs billions each year; one advanced ulcer can cost tens of thousands of dollars to treat.
- Patients with immobility, poor nutrition, or incontinence are at the highest risk.
That’s why choosing the right support surface is critical for both comfort and prevention.
Why the Right Mattress Can Save Skin
Special medical air mattresses are designed to help with this problem. They gently reduce pressure. They also regulate skin moisture and maintain steady airflow. These are not regular mattresses like those from popular traditional mattress brands. They are medical tools that aid in treating bedsores and wound care.
Some pressure mattresses use alternating pressure therapy. Others use low air loss to keep the skin dry and cool. Each one offers a unique kind of patient comfort and healing. Choosing the right one depends on the patient’s medical condition, needs, and mobility level.
The wrong mattress can make things worse. But the right mattress can bring real relief. It can reduce pain, prevent pressure injuries, and support healing at home or in care settings.
What is an Alternating Pressure Mattress? (AP)
Alternating Pressure mattresses contain sets of air cells that cyclically inflate and deflate, shifting the load away from one area to another. This active pressure redistribution reduces continuous pressure exposure and can improve tissue perfusion for immobile patients. Extensive randomized evaluations and reviews indicate that AP devices can reduce the incidence of pressure injuries compared to standard foam in high-risk populations; however, outcomes depend on the device design, patient risk, and clinical use.
Best for: patients who cannot reposition themselves, have a moderate risk (Braden 13–14), or have stage 1–2 ulcers where pressure redistribution is the primary need.
Considerations: Some users may experience micro-movement; ensure that pump noise and power backup plans are suitable for the care setting.
Some popular models include:
- Vive Health Alternating Pressure Pad System
- MedVance APM2
- Drive Medical Alternating Pressure Pump and Pad
What is a Low Air Loss (LAL) Mattress?
Low Air Loss mattresses deliver a continuous flow of air through the cover/surface to manage the microclimate, keeping the skin drier and cooler. This helps reduce maceration caused by perspiration or incontinence and is often selected for fragile skin or deeper wounds that require moisture control. LAL systems are less about cyclical pressure shifting and more about the skin environment.
Best for: incontinence, heavy moisture exposure, fragile or macerated skin, and many stage 3–4 wounds that require microclimate control.
Considerations: Some LAL units offer low-pressure support and may be combined with other systems for pressure redistribution.
Some popular models include:
- Hillrom AccuMax Quantum VPC
- Invacare microAIR MA95Z
- Drive Medical Low Air Loss/Alternating Pressure Mattress
Many brands also include whisper-quiet air pumps.
Low Air Loss vs. Alternating Pressure: Side-by-side Comparison
By now, you know that both mattress types help with bedsores and wound care. But they work in different ways. One moves air to shift pressure. The other keeps the skin cool and dry. So, which one is right for your needs?
Let’s make it easier with a side-by-side chart.
| Feature | Alternating Pressure Mattress | Low Air Loss (LAL) Mattress |
| Primary Mechanism | Air cells inflate/deflate in cycles to shift pressure points | Constant airflow through small holes to manage skin temperature and moisture |
| Main Goal | Active pressure redistribution to prevent pressure ulcers | Continuous microclimate management and constant low pressure |
| Pressure Ulcer Stage | Best for stage 1 and 2 ulcers or prevention | Best for stage 3 and 4 ulcers or moisture-prone skin |
| Moisture/Heat Control | Limited, not the main feature | Excellent for skin maceration and incontinence management |
| Ideal Patient Profile | Patients with low mobility who can’t shift weight on their own | Patients with fragile skin or heavy moisture exposure |
| Patient Sensation | May feel light movement or air shifts; some models can adjust settings | Feels steady and quiet; provides a stable therapeutic mattress experience |
| Air Retention | Holds air well after inflation; needs minimal adjustment | May slowly deflate over time; may require periodic reinflation |
| Durability | Often more durable, built for longer-term hospital or home care use | Material may be less puncture-resistant (vinyl, rubber, lightweight plastic) |
The Best of Both: Hybrid Mattresses
Sometimes, choosing between two good things can be hard. What if you didn’t have to choose? In that case, you can go with hybrid mattresses. They give you the benefits of both low air loss and alternating pressure in one supportive system.
These mattresses are often called combination pressure therapy mattresses. They combine two important features:
- Active pressure shifting (like an alternating pressure mattress)
- Continuous airflow for microclimate management (like a low air loss mattress)
How Does a Hybrid Mattress Work?
A hybrid mattress uses advanced air systems. Some parts inflate and deflate to relieve pressure. At the same time, tiny air holes release a gentle stream of air across the skin. So, while one part of the mattress is moving pressure away, the other is keeping the skin dry and cool.
Some trusted Hybrid Mattress Examples:
- Med-Aire Low Air Loss Mattress Replacement System with Alternating Pressure from Drive Medical
- Protekt Aire 3000 Low Air Loss Mattress System
- Span America PressureGuard APM2
Benefits of Hybrid Mattresses
- Combines pressure redistribution and moisture control
- Helps in all pressure ulcer stages, especially stages 3 and 4
- Reduce the risk of skin maceration and friction injuries
- Ideal for long-term hospital or home care beds
- Supports patient mobility and comfort
Who Needs a Hybrid Mattress?
A hybrid mattress is best for patients with both high moisture risk and high immobility. It’s also ideal for patients with slow-healing wounds, incontinence, or multiple skin concerns.
How to Choose Using the Braden Scale
Choosing a mattress for someone you love can feel overwhelming. But there’s a helpful tool that nurses and healthcare providers use. It’s called the Braden Scale. You can use it too, even at home.
The Braden Scale helps you assess the likelihood of someone developing pressure injuries. It gives a score based on a few simple things. Then, based on that score, you can choose the best mattress for preventing bed sores or wound care.
The Braden Scale looks at six key areas. Each one gets a score from 1 to 4 (or 1 to 3 in some cases). The overall score ranges from 6 to 23.
- A lower score means a higher risk of skin damage
- A higher score means lower risk
Here are the six areas it checks:
- Sensory Perception: This measures how well the person can feel discomfort or pain caused by pressure. If they cannot feel when their skin hurts or becomes sore, they are at higher risk for pressure injuries.
- Moisture: This refers to the frequency of the person’s skin becoming wet due to sweat, urine, or other bodily fluids. Too much moisture makes the skin soft and weak, increasing the likelihood of skin breakdown.
- Activity: This checks how active the person is during the day. Someone who lies in bed all the time has a higher risk of pressure ulcers because they don’t move enough to relieve pressure.
- Mobility: This measures how easily a person can move or shift positions independently. If they cannot turn or move without help, pressure builds up in one spot for too long.
- Nutrition: This checks if the person is eating well and getting the right nutrients. Poor nutrition hinders skin healing and increases the risk of developing sores.
- Friction and Shear: This examines the amount of rubbing or sliding that occurs when a person moves or is moved in bed.
Using the Braden Scale to Choose
The Braden Scale helps estimate the risk of pressure injuries (score 6–23).
| Braden Score | Risk Level | Suggested Mattress Type |
| 19-22 | No or low risk | Standard foam (including advanced foam mattress technology) or pressure relief cushion |
| 15-18 | Mild risk | Foam mattress with some pressure relief features |
| 13-14 | Moderate risk | An alternating pressure mattress is recommended |
| 10-12 | High risk | Low air loss or a hybrid mattress is suggested |
| 9 or below | Very high risk | An alternating pressure mattress recommended |
Frequently Asked Questions
What is the main purpose of a low air loss mattress?
A low air loss mattress helps keep the skin dry and cool. It gently releases air to reduce moisture and heat. This helps prevent and heal pressure sores, especially for patients with incontinence or fragile skin integrity.
Can you use regular sheets on an alternating pressure or low air loss mattress?
Yes, but it’s best to use thin, breathable sheets. Thick or tight sheets can block airflow or reduce pressure changes. Always check the mattress manual for sheet recommendations.
How long should a patient stay on an alternating pressure mattress?
A patient can stay on an alternating pressure mattress as long as needed. Many people use them full-time, especially if they are bedridden. Just make sure the mattress is working properly and check it often.
What happens to an air mattress during a power outage?
If the power goes out, the mattress will slowly lose air over time. Some models stay inflated for a short while. It’s good to have a backup plan or manual pump for emergencies.
Is an alternating pressure mattress noisy?
Most newer models are very quiet. They use low-noise pumps designed for comfort and sleep. You may hear a soft hum, but it’s usually gentle and soothing.
Can you put an alternating pressure mattress on top of a regular mattress?
Yes, many alternating pressure systems are overlays and go on top of a regular bed. But if using a full replacement system, it should go on a hospital bed frame or a solid base. Follow the brand’s setup guide. (Note: For non-medical adjustable air beds for home use, different rules apply).
How do you clean a low air loss or alternating pressure mattress?
Unplug the pump first. Then wipe the surface with warm water and mild soap. Avoid harsh chemicals. For deep cleaning, follow the user manual or ask a healthcare provider. Some models have a removable mattress cover for easier cleaning.
Can alternating pressure mattresses operate in static mode?
Yes, many alternating pressure mattresses have a static mode option. This allows the mattress to maintain constant pressure without alternating, which can be useful during patient transfers or certain medical procedures.
Conclusion
Choosing the right mattress is about healing as well. Whether you need dryness and moisture control or gentle pressure movement, both systems offer real relief. This low air loss mattress vs alternating pressure mattress guide has shown you the differences clearly.
Go with low air loss mattresses if your main concern is skin moisture or incontinence. Choose an alternating pressure mattress if you need to improve circulation and reduce constant pressure. Or pick a hybrid mattress to get the best of both.
For those needing non-medical solutions, explore eco-friendly organic mattress options.
Final Takeaway:
- Choose Low Air Loss for fragile, moisture-prone skin.
- Choose Alternating Pressure for immobile patients needing circulation support.
- Choose Hybrid if both problems exist.
Mattress choice is only one part of prevention; combine it with regular repositioning, good nutrition, and skin care. This ensures the best chance of protecting skin health and improving recovery.
