How to Vacuum Bed | Trauma Immobilization Steps

A vacuum mattress immobilizes a patient by molding around the body and evacuating air until semi-rigid, securing them for transport.

When someone suffers a suspected spinal fracture or serious extremity injury, rapid and safe transport becomes the priority. A vacuum mattress—also called a vacuum splint or vacuum stretcher—offers a reliable way to stabilize the patient during that critical window. Understanding the proper technique matters because incorrect use can compromise both safety and comfort.

What Is a Vacuum Mattress and When Is It Used?

A vacuum mattress is a sealed pad filled with polystyrene beads. Once placed under the patient and molded to their body, air is evacuated from the mattress, causing the beads to lock together into a semi-rigid shell that holds the patient securely. It is designed for temporary immobilization during preclinical and early clinical care—not for permanent immobilization.

Medical teams use these devices primarily for patients with suspected spinal injuries or unstable extremity fractures. TYROMONT, a manufacturer of these devices, states its vacuum mattresses are intended for “preclinical assistance and the first phase of clinical support” and should only be used by medical specialists who are trained and regularly instructed on the product.

Step-by-Step: How to Use a Vacuum Mattress

Both TYROMONT and EVAC-U-SPLINT publish detailed operating procedures. The steps below combine the essential actions from both manufacturers into a single reliable sequence.

Prepare the Mattress and Patient

Lay the mattress flat on the ground or stretcher next to the patient. Position it so the first buckle sits in line with the patient’s armpit (axilla). Remove the valve cap and release any residual vacuum by pushing in the valve stem until the mattress becomes pliable. Smooth the beads into a level, even surface across the mattress.

Before placing the patient, check for open wounds or non-intact skin. TYROMONT instructs that these must be sterilized or dressed according to aseptic standards before the mattress is applied. Never place the mattress directly against an untreated open wound.

Position the Patient and Evacuate Air

Using a standard log-roll technique, roll the patient onto the mattress while maintaining spinal alignment. Connect the patient restraint strap if the mattress includes one. Close the belts and tighten the straps to hold the patient in position.

Connect the suction hose or adapter to the mattress valve and evacuate air. EVAC-U-SPLINT specifies evacuating “enough air to make the mattress semi-rigid”—not fully rigid. TYROMONT says to remove the hose once sufficient stability is achieved. After removal, check that all belts remain tight and that the patient is comfortable.

Common Mistakes and Safety Cautions

The most frequent error is treating the vacuum mattress as a permanent immobilization solution. TYROMONT explicitly warns it is “not suited for permanent immobilisation.” It provides transport support only, and patients should be transferred to definitive care promptly.

Other common mistakes include:

• Skipping wound care—open wounds must be dressed before mattress application.
• Not tightening straps or failing to check comfort after evacuation.
• Over-evacuating to full rigidity, which reduces patient comfort without improving safety.
• Using the cover belts as a transport fixation—TYROMONT notes they are support for forming and fixing, not a substitute for proper patient securing.

Moving the patient requires an adequate relocation method, per TYROMONT’s guidance. The mattress helps immobilize, but it does not replace a proper stretcher or ambulance cot.

Cleaning, Storage, and Maintenance

Proper care extends the mattress’s lifespan and prevents contamination between patients. TYROMONT recommends cleaning with water and detergent, avoiding extreme mechanical cleaning, and disinfecting only with alcohol-based disinfectants (ethanol or propanol). Solvents can damage the mattress material and must never be used. Dry the mattress carefully after cleaning.

Store the vacuum mattress in dry conditions, protected from direct sunlight. TYROMONT also notes that the mattress models VM08X02, VM08X07, and VM09X03 may only be used with a suitable cover with handles. Always verify the specific model’s cover compatibility before use.
