How to Choose the Right Kind of Portable Oxygen Concentrator

Given the crucial role oxygen plays in our well-being, the importance of a top-notch portable oxygen concentrator (POC) can’t be overlooked – especially for those whose health situations necessitate an extra oxygen boost. A POC provides that much-needed supplement, sending pure oxygen into your lungs and throughout your body, thereby empowering you to breathe easier and continue living a quality life.

Whether you are grappling with a condition like Chronic Obstructive Pulmonary Disease (COPD), or you just need the reassurance that you can access additional oxygen anytime, having a POC that aligns perfectly with your lifestyle and needs is vital.


How to choose the right kind of portable oxygen concentrator


Understanding Your Oxygen Needs

In finding a suitable portable oxygen concentrator (POC), the vital first step is to understand your specific oxygen needs. This process involves three essential stages—consultation with medical professionals, determining your oxygen flow rate, and recognising your lifestyle and mobility needs. Each stage is integral to helping you choose a POC that not only meets your health requirements but also aligns with your lifestyle.


Consultation with a Healthcare Professional

Your journey to the right POC starts with a consultation with a healthcare professional. Doctors, respiratory therapists, or other medical specialists are well-versed in administering and interpreting tests that measure your body’s oxygen levels. They will translate these findings into tangible advice—providing precise details on the amount of supplementary oxygen you need. This professional input provides a solid foundation for your search, guiding you towards a POC that matches your medical needs.


Determining Your Oxygen Flow Rate Requirements

Once you’ve received the input from your healthcare provider, the next step is to understand your oxygen flow rate—basically, the volume of oxygen you require per minute, usually quantified in litres per minute (LPM). POCs offer diverse specifications, featuring different flow rate capabilities, and are often classified into two main types: continuous flow and pulse dose delivery concentrators. Your prescribed flow rate is instrumental in determining which type of POC aligns with your needs, ultimately guiding you to a device that ensures you receive the necessary oxygen supply.


Recognizing Your Lifestyle and Mobility Needs

Lastly, your lifestyle and mobility needs shape your POC choice. They dictate considerations such as the weight of the machine and the durability of the battery—factors that directly influence the usability and convenience of the POC. If you engage in physical activities frequently, you may require a lightweight and compact device, while those who travel or move around a lot might need a POC with extended battery life. A critical part of your POC decision-making process involves examining how a potential device fits into your lifestyle, ensuring a smooth integration of oxygen therapy into everyday living.


Types of Portable Oxygen Concentrators

The next step is understanding the different types of portable oxygen concentrators (POCs) available on the market. POCs come in two classifications: Continuous Flow and Pulse Dose. Each type comes with its strengths and specific scenarios for optimal use.


1. Continuous Flow POCs

Continuous flow portable concentrators are devices providing an unbroken, steady stream of oxygen, irrespective of whether the user is inhaling or exhaling. They mimic the way a home-based concentrator works, supplying a constant amount of oxygen per minute.


Suitable Scenarios for Continuous Flow POCs

Continuous flow POCs are best suited for users who require a stable and high flow of oxygen, including during sleep. Some users may have conditions that necessitate precise oxygen levels during their sleep cycle – continuous flow units are a great fit in these circumstances due to their consistent deliverability. Also, for those who breathe through their mouth (mouth breathers), or require high flow rates of oxygen, continuous flow units are often recommended.


Advantages and Limitations of Continuous Flow POCs


  • Consistency: Continuous flow POCs provide a reliable, steady stream of oxygen, making them ideal for users with high oxygen needs, including nocturnal use.
  • Versatility: They are often compatible with CPAP or BiPAP devices, which aid in sleep apnea treatment.


  • Size and Weight: Given their design to produce a constant flow of oxygen, these POCs tend to be larger and heavier than pulse dose models.
  • Battery Life: The continuous generation of oxygen often leads to shorter battery life. Therefore, these devices may require frequent recharging or battery swaps.

Navigating the benefits and potential drawbacks of Continuous Flow POCs is crucial to match the right device with your specific lifestyle and therapeutic needs.


2. Pulse Dose POCs

A distinct category of portable oxygen concentrators is Pulse (or Demand) Dose POCs. Unlike their continuous flow counterparts, these machines deliver oxygen only when the user inhales. They utilise intelligent delivery technology, sensing the beginning of an inhalation cycle and supplying a burst of oxygen at that precise moment.


Suitable Scenarios for Pulse Dose POCs

Pulse dose POCs are suitable for individuals with stable breathing patterns. Since they provide oxygen on demand, they are optimal for daytime use when the user is awake and has a regular respiration rate. The devices are ideal for individuals leading active lifestyles, as they are smaller, lightweight, and typically come with extended battery life.


Advantages and Limitations of Pulse Dose POCs




  • Portability: Pulse dose POCs are typically lighter and more compact than continuous flow units, making them ideal for people on the go.
  • Battery Efficiency: Because they only deliver oxygen during inhalation, these units generally have longer battery life.
  • Delivery Efficiency: The on-demand delivery signifies less wastage of oxygen, leading to overall increased efficiency.


  • Inhalation Dependent: Pulse dose units depend on the patient’s inhalation effort to deliver oxygen, which could be disadvantageous for individuals with weak breath or irregular breathing patterns.
  • Unsuitable for High Flow Rates: These concentrators might not provide the needed oxygen levels for individuals requiring high constant oxygen flow, especially during sleep or at rest.

In the quest for the right oxygen concentrator, one should weigh these factors to decide if the portability and efficiency of pulse dose POCs outweigh their limitations in specific situations.


Portability and Size

One of the most crucial aspects of selecting a portable oxygen concentrator is understanding the significance of portability and size in your daily life. These factors directly impact the overall convenience and satisfaction you experience with your POC. In the following sections, we delve into size and weight considerations, battery life and power options, and valuable portability features—all of which contribute to making an informed decision on the POC that best suits your needs.
