Group II Therapeutic System for Advanced Pressure Ulcer Treatment
The Prius Rhythm Multi is a premium Group II therapeutic support system that combines True Low Air Loss technology with alternating pressure and pulsation therapy. Designed for patients with existing stage 1-4 pressure ulcers or those at high risk, this advanced system delivers exceptional pressure relief, optimal microclimate management, and bariatric support up to 600 lbs—all powered by an ultra-high 1275 LPM airflow system.
Advanced Therapeutic Technology
The Rhythm Multi represents the next level in pressure ulcer prevention and treatment, offering features typically found only in hospital-grade systems. Unlike standard alternating pressure mattresses, this system provides True Low Air Loss technology that actively manages heat and moisture while delivering continuous therapeutic pressure redistribution.
True Low Air Loss Technology
True Low Air Loss is the gold standard for advanced wound care. The system continuously circulates air through the mattress cover at a rate of up to 1275 liters per minute, creating a therapeutic microclimate that:
- Reduces heat buildup that can damage fragile skin
- Manages moisture from perspiration and incontinence
- Keeps skin cool and dry to promote healing
- Prevents maceration that leads to tissue breakdown
- Creates an optimal environment for wound healing
Three Therapeutic Modes
1. Alternating Pressure Mode: The mattress features 18 cell-in-cell 8-inch bladders that provide 3-in-1 alternating pressure therapy. Cycle times are fully adjustable from 3 to 95 minutes, allowing caregivers to customize treatment:
- 3-20 minutes: Adjustable in 1-minute increments for precise control
- 20-95 minutes: Adjustable in 5-minute increments for extended cycles
2. Pulsation Mode: A unique alternative to traditional alternating pressure, the pulsation setting gently raises and lowers pressure across the entire mattress every 90 seconds. This creates a gentle massage effect that promotes circulation without the distinct alternating cell pattern, ideal for patients who find standard alternating uncomfortable.
3. Static Mode: Provides constant, evenly distributed low pressure support when needed for procedures, transport, or patient preference.
Key Features & Clinical Benefits
Ultra-High Airflow: 1275 LPM
The powerful compressor delivers industry-leading airflow—significantly higher than standard systems. This exceptional airflow capacity ensures optimal Low Air Loss performance even for bariatric patients up to 600 lbs, maintaining therapeutic benefits across the full weight range.
Microprocessor Pressure Sensing
Advanced microprocessor technology continuously monitors and adjusts pressure levels to maintain optimal therapeutic support. The system automatically compensates for patient movement, weight distribution changes, and positional adjustments.
10 Comfort Levels
The user-friendly control panel offers 10 adjustable comfort settings, allowing precise calibration for individual patient needs, weight, and clinical requirements. This level of customization ensures optimal pressure relief while maintaining patient comfort.
Happy Heel Technology
The last 5 air cells in the mattress are specially designed to provide extra softness and protection for the heels—a common site for pressure ulcer development. This targeted pressure relief helps prevent heel ulcers, which are notoriously difficult to heal.
Integrated Safety Features
- 2-Inch Convoluted Foam Base: Provides continued support and patient safety during power failures
- Audible and Visual Alarms: Alerts caregivers to low pressure or power issues

Who Should Use the Rhythm Multi?
This advanced therapeutic system is specifically designed for:
- Patients with existing pressure ulcers (stages 1-4) requiring active treatment
- High-risk patients with multiple risk factors for pressure ulcer development
- Bariatric patients up to 600 lbs requiring therapeutic support
- Patients with atopic dermatitis or other skin conditions requiring microclimate management
- Long-term care residents with significant mobility limitations
- Post-surgical patients requiring extended immobilization
- Patients who have failed with standard alternating pressure systems
- Home care patients requiring hospital-grade therapeutic support
Clinical Applications
Active Treatment: The combination of True Low Air Loss and alternating pressure makes the Rhythm Multi highly effective for treating existing pressure ulcers up to stage 4. The system addresses both pressure redistribution and microclimate management—the two critical factors in wound healing.
Prevention: For high-risk patients, the Rhythm Multi provides superior preventive therapy that goes beyond standard alternating pressure, significantly reducing the likelihood of pressure ulcer development.
Bariatric Care: The 600 lb weight capacity with maintained therapeutic airflow (1275 LPM) makes this one of the few systems that delivers true clinical benefits for bariatric patients, not just structural support.
Comfort & Compliance: The pulsation mode and 10 comfort levels ensure patients remain comfortable during extended therapy, improving compliance and overall outcomes.

Frequently Asked Questions
Q: What makes this a "Group II" mattress?
A: Group II classification indicates an advanced therapeutic support surface that provides both pressure redistribution AND microclimate control (through Low Air Loss technology). This classification is required for certain Medicare coverage scenarios and indicates a higher level of clinical intervention than Group I (alternating pressure only) systems.
Q: How is True Low Air Loss different from regular alternating pressure?
A: Regular alternating pressure focuses only on redistributing pressure. True Low Air Loss adds active airflow through the cover, which manages heat and moisture—critical factors in wound healing. The 1275 LPM airflow creates a therapeutic microclimate that keeps skin cool, dry, and optimally conditioned for healing.
Q: What is the pulsation mode used for?
A: Pulsation mode gently raises and lowers the entire mattress every 90 seconds, creating a massage-like effect. Some patients find this more comfortable than traditional alternating pressure, and it still provides excellent pressure redistribution. It's particularly useful for patients who are sensitive to the distinct "alternating" sensation.
Q: Can this handle bariatric patients?
A: Yes. The 600 lb capacity is genuine bariatric support, not just structural weight capacity. The 1275 LPM airflow ensures the Low Air Loss technology remains fully therapeutic even at maximum weight—many systems lose effectiveness with heavier patients.
Q: Why are there so many cycle time options (3-95 minutes)?
A: Different clinical situations call for different cycle times. Shorter cycles (3-10 minutes) provide more frequent pressure changes for higher-risk patients, while longer cycles (20-95 minutes) may be more comfortable for patients during recovery or less acute phases. The flexibility allows clinicians to optimize therapy as patient needs change.
Q: What is Happy Heel technology?
A: The last 5 air cells are specially designed to be extra soft, providing targeted pressure relief for the heels. Heel pressure ulcers are common and difficult to treat, so this built-in heel protection is an important preventive feature.
Q: How long does setup take?
A: Initial setup takes approximately 15-20 minutes. Place the mattress on the bed frame, connect the control unit, power on, and select your settings. The system will automatically inflate and calibrate. The control panel is intuitive and user-friendly.
Q: Is it noisy?
A: Despite the powerful 1275 LPM airflow, the compressor is designed for quiet operation suitable for patient rest and sleep.
Q: What happens during a power failure?
A: The 2-inch convoluted foam base provides continued support and safety during power outages. The mattress will gradually deflate to the foam base, which maintains patient safety. The alarm will alert caregivers to the power issue.
Q: How do I clean it?
A: The waterproof nylon cover can be wiped down with standard hospital-grade disinfectants. Follow the manufacturer's cleaning protocols in the user manual.
Q: Can I use this at home?
A: Absolutely. While this is hospital-grade equipment, it's designed for use in both clinical facilities and home care settings. Many patients with complex wounds require this level of therapeutic support at home.
