What is a Portable Oxygen Concentrator?
A portable oxygen concentrator (POC) is a medical device that takes in regular air (which contains about 21% oxygen) and concentrates it to deliver 90-95% pure oxygen to you through a nasal tube or mask. Unlike heavy oxygen tanks that need refilling, these devices run on electricity or rechargeable batteries and never run out of oxygen as long as they have power.
How They Work:
- Pull in air from around you
- Remove nitrogen and other gases using special filters
- Deliver concentrated oxygen through tubing
- Automatically adjust to your breathing pattern
Types of Oxygen Delivery
Pulse Dose (Most Common):
- Delivers oxygen only when you breathe in
- More battery-efficient
- Lighter weight
- Good for most daily activities
Continuous Flow:
- Provides steady stream of oxygen
- Better for severe conditions
- Heavier and uses more power
- May be needed for sleep or high oxygen requirements
Who Needs a Portable Oxygen Concentrator?
Your doctor may prescribe oxygen therapy if you have:
- Chronic Obstructive Pulmonary Disease (COPD) – Most common reason
- Emphysema – Part of COPD family
- Chronic Bronchitis – Another COPD condition
- Pulmonary Fibrosis – Lung scarring
- Heart Failure – When heart can’t pump efficiently
- Severe Asthma – In some cases
- Sleep Apnea – Combined with CPAP therapy
Medical Tests Required:
- Blood oxygen level (SpO2) below 88% at rest
- Arterial blood gas showing PaO2 ≤55 mmHg
- Exercise or sleep studies showing oxygen drops
Medicare Coverage Reality Check
What Medicare Actually Covers
Medicare Part B covers 80% of the rental cost of oxygen equipment after you meet your annual deductible of $257 in 2025. Important: Medicare does NOT cover purchasing a portable oxygen concentrator – only rentals.
Your Monthly Costs:
- You pay 20% of rental fee (typically $30-$80 per month)
- First 36 months: You make monthly payments
- After 36 months: Supplier continues providing equipment for free
- Total 5-year commitment with supplier
Medicare Requirements
- Doctor must prescribe oxygen as “medically necessary”
- Must use Medicare-approved supplier
- Doctor must provide evidence you need portable unit vs. tanks
- Regular testing to confirm ongoing need
Reality Check: If Medicare won’t approve a portable concentrator, you may need to purchase one yourself, which can cost $2,500-$4,000.

FAQs
Q: Can I buy a concentrator without a prescription? A: No. Portable oxygen concentrators require a prescription from a doctor. This is a safety requirement to ensure proper oxygen levels and medical supervision. Always consult your healthcare provider before making any oxygen therapy decisions.
Q: How long do these machines last? A: Quality units like the Inogen Rove 6 have an 8-year expected service life. With proper maintenance, many units last 5-8 years of regular use. Discuss maintenance schedules with your healthcare provider and equipment supplier.
Q: Can I sleep with a portable concentrator? A: Inogen portable oxygen concentrators are designed with Intelligent Delivery Technology to provide oxygen effectively during sleep. However, some people need continuous flow for sleep. Your doctor will determine the best oxygen delivery method for nighttime use.
Q: What happens if my concentrator breaks while traveling? A: Most manufacturers offer loaner programs. Airlines may provide emergency oxygen. Always have backup batteries and contact your supplier immediately. Discuss emergency backup plans with your healthcare provider before traveling.
Q: Are there any side effects from using oxygen? A: Some studies show breathing high oxygen concentrations for extended periods may have negative lung effects. Your doctor monitors this through regular testing. Follow your prescribed oxygen levels and attend all scheduled medical appointments.
