Portable Oxygen Concentrators for Post-Sepsis Recovery
Sepsis and ARDS can cause lasting lung damage. Find the right portable oxygen concentrator to improve your quality of life.
Why Oxygen Therapy After Sepsis?
ARDS & Lung Damage
Sepsis can lead to Acute Respiratory Distress Syndrome (ARDS), causing permanent lung damage and fibrosis. Even after recovery, patients may have reduced oxygen capacity.
- • Shortness of breath with exertion
- • Reduced exercise tolerance
- • Need for supplemental oxygen during activities
Improved Mobility
Portable oxygen concentrators (POCs) allow patients to leave home, travel, and maintain active lifestyles rather than being tethered to heavy oxygen tanks.
- • Lightweight and portable designs
- • Rechargeable batteries
- • FAA-approved for air travel
- • Continuous or pulse dose settings

Choosing the Right Portable Oxygen Concentrator
Key Considerations
- 1 Oxygen Output: Higher output (5L) is for continuous flow, lower (1-5L) for intermittent use.
- 2 Battery Life: Critical for travel and outdoor activities. Look for 6+ hours for full day use.
- 3 Weight: If you're weak from sepsis, choose a lightweight model (under 5 lbs) you can easily carry.
- 4 Noise Level: Important for discretion and comfort. Ultra-quiet models (<40dB) are available.
- 5 FAA Approval: Required if you plan to travel by air. All models listed above are FAA-approved.
- 6 Warranty & Support: Look for 2+ year warranty and responsive customer service.
When to Consult Your Doctor
Before purchasing, consult with your healthcare provider about:
- • Prescribed flow rate - Liters per minute needed
- • Pulse vs. continuous - Which setting is right for you
- • Oxygen saturation goals - Target SpO2 levels
- • Activity level - Match device to your lifestyle
