Low Air Loss Mattress Repair: Protecting Patients from Pressure Injuries

Low air loss (LAL) and alternating pressure (AP) mattress systems are sophisticated medical devices. They manage moisture, reduce interface pressure, and prevent pressure injuries in patients who are at moderate to high risk. When these systems malfunction, the clinical consequences are real — a patient who relied on the mattress for pressure relief is suddenly at elevated risk for skin breakdown.

Common Problems

Pump Alarm Lights

A deflation alarm usually means one or more cells have a leak. Identify the deflated cells by running your hand along the surface with the pump running — you may feel airflow from a seam or puncture.

Cell Deflation or Uneven Inflation

A single deflated cell typically indicates a puncture or failed internal connector. Individual cells can often be replaced without replacing the entire mattress surface.

Pump Motor Failure

When the pump motor fails, the entire surface deflates. Motor replacement is a standard repair that restores full function at a fraction of the cost of a new system.

Repair vs. Replace

For systems under 5 years old with a single component failure, repair is almost always the right economic choice — LAL systems range from $1,500 to $8,000 new, while typical repairs run $150–$600. OB1 will give you an honest assessment.
