| 1. Match the pressure range to the treatment goal | Adjustable pressure, pressure accuracy, and whether the device displays the selected pressure in mmHg. | Many limb systems provide adjustable pressures in approximately the 20–60 mmHg range. The prescribed level depends on the condition, limb, garment, and clinical assessment. | Higher pressure is not automatically more effective. Excessive pressure may cause pain, numbness, skin injury, or impaired circulation. | What pressure range is appropriate for the intended use, and can a clinician set or limit the maximum pressure? |
| 2. Choose the correct compression mode | Sequential, gradient, uniform, or single-chamber inflation. | Sequential gradient: chambers inflate from distal to proximal, commonly used when a graduated compression pattern is desired. Uniform or single-chamber: applies similar pressure across the treatment area. | The inflation pattern affects comfort, fluid movement, and suitability for different clinical protocols. | Does the device inflate from the hand or foot upward, and can the sequence or gradient be changed? |
| 3. Check the number of chambers | One, two, four, six, eight, or more independently controlled chambers; chamber overlap; and garment coverage. | Multi-chamber systems can create a more graduated sequence. The appropriate number depends on whether treatment covers the foot, lower leg, thigh, arm, or trunk. | More chambers may allow finer control, but can also increase setup complexity and cost. | Does the garment cover the full treatment area, and are adjacent chambers properly overlapped? |
| 4. Review cycle timing and treatment duration | Inflation time, hold time, deflation or release time, cycle frequency, and programmable session length. | Treatment protocols vary widely. Sessions may last roughly 20–60 minutes, but the duration and cycle should follow the prescribed protocol rather than a generic default. | A suitable release phase can improve comfort and allows the user to monitor skin, sensation, and symptoms between cycles. | Can the session stop automatically, and can inflation, hold, and release times be adjusted independently? |
| 5. Verify garment fit and body-area coverage | Available sizes, adjustable closures, limb circumference limits, left/right compatibility, and foot, hand, thigh, or trunk coverage. | The garment should fit securely without folds, gaps, twisting, or excessive tightness. Sizing must be based on measured limb dimensions, not clothing size alone. | Poor fit can create uneven pressure, reduce treatment coverage, and increase the risk of discomfort or skin damage. | What measurements are required, and is a different garment available if swelling changes? |
| 6. Prioritize monitoring and safety features | Pressure alarms, over-pressure protection, leak detection, emergency release, pause controls, and power-failure behavior. | Look for clear pressure readouts, automatic shutoff or pressure limitation, and a quick-release function. These features support safer home and clinical use. | A device should be easy to stop if pain, numbness, color change, dizziness, shortness of breath, or unusual swelling occurs. | Are there contraindications or precautions for suspected blood clots, severe arterial disease, uncontrolled heart failure, infection, or open wounds? |
| 7. Consider usability, maintenance, and clinical support | Controls, display readability, noise, portability, cleaning instructions, replacement garments, service support, and data logging. | Choose a system that the intended user can put on correctly, operate consistently, and clean according to the manufacturer’s instructions. | Ease of use improves adherence and reduces errors in pressure, timing, or garment placement. | Is training available, can settings be locked, and are replacement parts and technical assistance accessible? |
