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
