How Air-Flow Mattresses Prevent Pressure Ulcers

October 20, 2025

Comments

Air-flow mattresses are designed to prevent pressure ulcers - painful wounds caused by prolonged pressure on the skin - by redistributing pressure and keeping the skin dry. Here's how they work:

Alternating Pressure Technology: Air cells inflate and deflate in cycles, ensuring no single area of the body bears pressure for too long. This helps maintain blood flow and reduce skin damage.
Low Air Loss Function: Continuous airflow keeps the skin dry and cool, reducing moisture that can lead to breakdown.
Key Features: These mattresses include quiet air pumps, durable air cells, waterproof covers, and customizable settings for patient comfort.

Studies show air-flow mattresses significantly reduce the risk of pressure ulcers compared to foam or gel surfaces. Combined with proper skin care and repositioning, they are an effective tool for patients with limited mobility.

How Air-Flow Mattresses Work

Alternating Pressure Technology

Air-flow mattresses rely on alternating pressure technology, which uses a network of air cells that inflate and deflate in carefully timed cycles. When one set of cells deflates, the neighboring cells stay inflated, creating a dynamic support system across the mattress surface.

This cycling action provides brief periods of zero pressure beneath the skin - something traditional foam or gel mattresses simply can’t achieve^[6]. By continuously redistributing weight, the system prevents any single area of the body from bearing pressure for too long, which could otherwise restrict blood flow and lead to complications.

This technology is particularly effective in protecting high-risk areas like the hips, tailbone, and heels. In fact, a Cochrane review of 32 studies involving 9,058 participants (average age: 69) concluded that active, air-filled surfaces may lower the risk of pressure ulcers compared to foam or gel surfaces^[3]. The mattress pump system can be fine-tuned based on factors like the patient’s weight and specific needs. Settings range from low-pressure modes for frail individuals to higher-pressure options for those needing firmer support. Additionally, the low air loss feature works alongside this system to keep the skin dry and healthy.

Low Air Loss Function

Many air-flow mattresses also include a low air loss function to address moisture control, which is crucial for maintaining healthy skin. This feature works by circulating air through tiny perforations, promoting airflow that keeps the skin dry and cool.

This constant airflow helps evaporate sweat and reduces humidity around the body, preventing skin from softening due to moisture. It also maintains a comfortable temperature, which can make a big difference for patients who spend long hours in bed.

This feature is especially helpful for individuals with incontinence or those who sweat heavily. Unlike the intermittent cycling of alternating pressure, the low air loss function operates continuously, ensuring consistent moisture management and skin protection.

Main Components of Air-Flow Mattresses

To understand how these features come together, it’s helpful to break down the key components of air-flow mattresses. These mattresses combine several elements to deliver both alternating pressure and low air loss capabilities:

Air Pump: The heart of the system, the pump controls pressure levels and manages the timing of inflation and deflation cycles. Modern pumps are designed to operate quietly and often include digital displays for precise adjustments.
Air Cells or Chambers: These make up the mattress surface and are arranged in rows or zones. Built from durable, puncture-resistant materials, the cells ensure consistent pressure distribution. Advanced models may have specialized zones, like heel relief sections that can deflate entirely to "float" the heels, reducing pressure on these sensitive areas^[5].
Waterproof Cover: Protecting the internal components, the cover is easy to clean and designed for infection control. High-quality covers balance breathability - important for the low air loss function - with being impermeable to fluids.

Additional features often include side bolsters to prevent patients from rolling off the mattress and seat inflation options for extra support when the bed is in an upright position^[5]. Most clinical-grade air-flow mattresses are built to handle a range of patient weights, typically supporting up to 350-500 pounds. Caregivers can customize the settings for pressure levels and cycle timing to meet individual needs, ensuring optimal comfort and protection for each patient.

Benefits of Air-Flow Mattresses for Pressure Ulcer Prevention

Pressure Redistribution and Skin Protection

Air-flow mattresses are designed to continuously redistribute pressure across the body, helping to reduce strain on sensitive areas. This is especially important for bony prominences - spots where bones are close to the skin, like the hips, tailbone, and heels^[1]. By using alternating pressure technology, these mattresses intermittently relieve pressure, ensuring better blood flow to vulnerable areas. They also minimize shear forces, which can damage the skin. Clinical studies consistently back these advantages, making air-flow mattresses a reliable option for protecting skin health.

Clinical Evidence Supporting Effectiveness

Research strongly supports the role of air-flow mattresses in preventing pressure ulcers. A Cochrane review analyzing 32 studies (involving 9,058 participants with an average age of 69) found that active air surfaces were more effective at reducing pressure ulcer risks compared to foam surfaces^[3]. Similarly, a review of 17 studies (2,604 participants, mean age: 72) highlighted the benefits of reactive air-filled surfaces in lowering pressure ulcer incidence^[2]. In one notable case, the use of the Dyna-Form Mercury Advance mattress led to a 39% drop in pressure ulcer cases^[4].

Additional Benefits for Patients

Beyond preventing ulcers, air-flow mattresses offer other meaningful advantages for patients. They enhance comfort by improving sleep quality and reducing pain, while also promoting independent repositioning. These systems maintain optimal temperature and moisture levels through continuous low air loss, which helps protect the skin. Plus, their quiet operation ensures minimal disturbances, contributing to a more restful and healing environment.

Best Practices for Using Air-Flow Mattresses

Proper Setup and Adjustment

Start by placing the mattress on a sturdy bed frame to ensure stability. Attach the air pump securely, and check that all hoses are free from kinks or blockages. Inflate the mattress completely following the manufacturer's instructions, and adjust the pressure settings to match the patient's weight and comfort needs.

Use the control panel to fine-tune the pressure. For patients with limited mobility or those at higher risk, lower pressure settings can help with better immersion and pressure redistribution. However, ensure the patient does not sink to the point of touching the bed frame underneath.

Check that the alternating pressure cycles are functioning correctly. Regularly reassess and adjust the settings as needed, especially if the patient’s condition changes. Once everything is set, focus on maintaining proper skin care and repositioning to maximize the mattress's effectiveness.

Monitoring Skin Health and Repositioning

Examine the patient’s skin at least once per shift for any signs of redness, swelling, or changes in temperature. Pay close attention to areas prone to pressure, like the heels, sacrum, and hips. If you notice early warning signs such as blistering or open wounds, act quickly to modify the care plan and prevent further complications.

Repositioning schedules should be tailored to each patient, but for high-risk individuals, clinical guidelines often recommend repositioning at least every two hours. This helps reduce the pressure and shear forces that contribute to skin breakdown.

Maintenance and Hygiene

Keeping the mattress clean and functional is critical for its performance. Use a mild soap or disinfectant approved by the manufacturer to clean all surfaces, including the air cells and covers. Pay extra attention after patient discharge or when there’s visible soiling.

Inspect the air pump and hoses regularly for leaks or signs of wear. Replace filters as recommended, and address any issues like uneven inflation or inconsistent pressure cycles as soon as they arise to avoid interruptions in care.

To simplify maintenance, consider using PeelAways disposable bed sheets. These waterproof, multi-layer sheets create a protective barrier that keeps liquids from reaching the mattress. When soiling occurs, you can peel off the top layer to reveal a clean surface underneath, eliminating the need to disturb the patient or adjust the mattress settings.

When to Seek Medical Advice

Identifying Warning Signs

Even with the use of air-flow mattresses and proper hygiene, certain warning signs demand immediate attention. Persistent redness, warmth, or swelling over areas prone to pressure can indicate early tissue damage. If open sores, blisters, or any breaks in the skin appear, these are signs of more advanced pressure ulcers that need urgent evaluation. Additionally, symptoms of infection - such as pus, a foul smell, fever, or worsening pain - should never be ignored. Research highlights that catching and addressing these issues early can cut the risk of severe pressure ulcers by up to 50% ^[2].

Role of Caregivers and Medical Professionals

Caregivers play a critical role in spotting early signs of pressure ulcers. Daily skin checks are vital, especially focusing on bony areas where pressure sores often develop. Look for changes in color, temperature, or texture, and take note of any discomfort the patient reports. Those at higher risk include people who are bedridden or use wheelchairs, older adults (average age around 70), and individuals with chronic illnesses, poor nutrition, or incontinence.

Healthcare providers also have a significant part to play. They conduct regular risk assessments, guide caregivers, and create tailored care plans. These plans might include repositioning schedules, nutritional guidance, and tools like pressure-relieving devices alongside air-flow mattresses. According to NICE guidelines, daily skin checks are recommended for high-risk individuals, with more frequent monitoring if any warning signs emerge.

A team-based approach can further improve outcomes. Scheduled meetings between caregivers and medical professionals, shared care plans, and ongoing caregiver training all contribute to timely intervention. Document all skin assessments and communicate concerns promptly to help prevent complications.
