Pulse vs Continuous Flow Oxygen: What's the Difference?

When choosing an oxygen concentrator, one of the most important decisions is selecting the right flow type. Pulse flow and continuous flow deliver oxygen in very different ways, and understanding the difference is essential for effective oxygen therapy.

What Is Oxygen Flow?

Oxygen flow refers to how oxygen is delivered from a concentrator to the user. The two main types are pulse flow and continuous flow.

What Is Pulse Flow Oxygen?

Pulse flow oxygen delivers oxygen only when you inhale.

How it works:

  • Detects your breath
  • Delivers oxygen in bursts
  • Stops when you exhale

Best for:

  • Active users
  • Travel and mobility
  • Lower to moderate oxygen needs

Benefits:

  • Lightweight and portable
  • Longer battery life
  • Efficient oxygen use

What Is Continuous Flow Oxygen?

Continuous flow delivers a steady stream of oxygen at all times.

How it works:

  • Constant oxygen delivery
  • Measured in liters per minute (LPM)

Best for:

  • Higher oxygen needs
  • Sleep use
  • Home therapy

Benefits:

  • Consistent oxygen delivery
  • Works regardless of breathing pattern

Pulse Flow vs Continuous Flow: Key Differences

Feature Pulse Flow Continuous Flow
Delivery Breath-triggered Constant
Portability High Lower
Battery Life Longer Shorter
Best Use Travel Home use

Which Oxygen Flow Type Is Right for You?

Pulse Flow may be right if you:

  • Are active
  • Travel frequently
  • Need a portable solution

Continuous Flow may be right if you:

  • Need steady oxygen
  • Use oxygen at night
  • Have higher oxygen demands

Why Flow Type Matters

Choosing the correct flow type affects:

  • Oxygen effectiveness
  • Comfort
  • Mobility

Frequently Asked Questions
