Understanding Pulse & Continuous Flow

Pulse Flow vs. Continuous Flow: Key Differences in Portable Oxygen Concentrators If you're exploring portable oxygen concentrators (POCs) for the first time or seeking to understand more about your current device, it’s important to know the differences between pulse flow and continuous flow oxygen technologies. These variations significantly impact the size, weight, and functionality of portable oxygen solutions. This guide breaks down these differences and helps you determine the best option for your needs.

What is Continuous Flow Oxygen?

Continuous flow oxygen delivers a steady, uninterrupted stream of oxygen at a constant rate, measured in litres per minute. This type of oxygen delivery is commonly used for patients who require a constant supply of oxygen, usually administered through a nasal cannula or mask. Key Features of Continuous Flow Oxygen:

Home Systems: Most home oxygen concentrators and oxygen cylinders provide continuous flow oxygen. These systems are designed with larger components to handle higher flow rates.
Portable Systems: Portable oxygen concentrators with continuous flow settings are rare and typically offer a fraction of the capacity found in home systems. The compact design of portable units limits their ability to provide high continuous flow rates.

What is Pulse Flow Oxygen?

Pulse flow oxygen is a modern technology that optimizes oxygen delivery by providing short bursts of oxygen in sync with your breathing pattern. This on-demand system releases a pulse of oxygen when you inhale through a nasal cannula, which reduces waste and enhances efficiency. Advantages of Pulse Flow Oxygen:

Portability: Pulse flow concentrators are compact and lightweight, making them ideal for users who are active and on-the-go. For instance, the INOGEN ONE G4, one of the smallest and lightest POCs available, weighs slightly more than a bag of sugar and features three pulse settings.
Efficiency: Pulse flow systems are designed to be more energy-efficient. They deliver oxygen only when needed, extending battery life and contributing to the device’s smaller size.
Freedom and Independence: The compact design and rechargeable batteries of pulse flow devices offer users greater mobility and independence.

Comparing Pulse Flow and Continuous Flow Portable Oxygen Concentrators

When choosing between pulse flow and continuous flow oxygen concentrators, consider these factors:

Size and Portability: Pulse flow concentrators are typically more portable and better suited for an active lifestyle, while continuous flow models are often larger and less suited for mobility.
Battery Life: Pulse flow devices generally offer longer battery life due to efficient oxygen delivery. Continuous flow units may have shorter battery life and are bulkier.
Usage Requirements: Continuous flow is necessary for conditions like sleep apnoea, where a constant supply of oxygen is critical. Pulse flow is ideal for those needing flexibility and portability.
