How Long You Can Use Portable Oxygen Concentrators


Increasing Use of Portable Oxygen Concentrators for Respiratory Support


The landscape of respiratory care has been revolutionised by the introduction of portable oxygen concentrators. Offering unmatched mobility and freedom, these devices are becoming indispensable for individuals with chronic respiratory conditions. Their increasing prevalence emphasises the necessity for potential and current users to comprehend the extent of their reliability and operational scope.

Understanding the operational duration of portable oxygen concentrators is critical. It impacts not just the management of respiratory conditions but also affects daily planning, travel, and overall quality of life. For individuals who are dependent on these devices, this knowledge is essential for the uninterrupted continuity of their oxygen therapy.

Several related factors play a part of how long a portable oxygen concentrator can be used for. These encompass the type and model of the device, battery capacity, oxygen flow settings, environmental conditions, user activity levels, maintenance practices, and personal health requirements. Understanding each of these elements is vital for maximising the effective use of oxygen therapy devices.

Types of Portable Oxygen Concentrators


The longevity of use depends significantly on the type of concentrator selected, each suited to different user needs and lifestyles. Below, we will expand on the two types of portable oxygen concentrators that are available.


Pulse Flow Concentrators:


These are engineered to deliver oxygen in bursts synchronised with the user’s inhalation. When the user takes a breath, a sensor triggers the device to release a measured dose of oxygen, making it a demand-based system. These devices are typically smaller, lighter, and more energy-efficient, as they only provide oxygen when the user inhales, conserving the oxygen supply and extending battery life.


Continuous Flow Concentrators:


In contrast, these concentrators emit a constant stream of oxygen, regardless of the user’s breathing pattern. This mode is essential for individuals with higher oxygen demands, particularly those who require oxygen at night or have certain types of respiratory conditions that affect their breathing patterns, such as chronic obstructive pulmonary disease (COPD) or restrictive lung diseases. Although they tend to be larger and consume more power, continuous flow units are often necessary for those who need a steady and reliable oxygen supply.


Differences in Operational Efficiency and Impact on Usage Duration


The operational efficiency of a portable oxygen concentrator is a key factor in determining how long the unit can function before needing a recharge or battery replacement.

Pulse flow units typically offer increased efficiency; because they only deliver oxygen during inhalation, less oxygen is ‘wasted’, and the device consumes less power, resulting in longer battery life. Users can often enjoy several hours of additional use from a pulse flow device compared to a continuous flow model on a single battery charge.

Continuous flow concentrators, due to their constant oxygen delivery, naturally have a shorter battery life. They are best suited for users who need a fixed and continuous supply of oxygen, which requires more energy and, therefore, more frequent battery charges or changes. For those who rely on continuous flow, planning for power source access or carrying additional batteries is often necessary to maintain their oxygen therapy without interruption.


How the Type of Concentrator Affects the Overall Duration of Use


The type of portable oxygen concentrator a user chooses will significantly affect the overall duration of use.

Pulse flow models are generally favoured for daytime and ambulatory use, allowing users greater mobility and longer periods away from charging sources. They are ideal for users who are active and can tolerate periods when they are not receiving oxygen, such as between breaths.

For those whose clinical condition necessitates a consistent flow of oxygen, continuous flow models are essential, despite their reduced operational duration. These users need to consider their activity levels and access to power sources throughout the day to ensure uninterrupted oxygen therapy. In scenarios where extended use is required without access to power, users may need to plan for alternative power solutions or supplemental oxygen systems.

Battery Life and Capacity


The battery serves as the heart of a portable oxygen concentrator’s operational efficacy. It determines the span a user can remain mobile and breathe freely, without the constraints of being attached to a power source. Therefore, it is a crucial factor when it comes to the user’s independence and the ability to carry out daily tasks without restriction.

The distinction between the length of time that a concentrator functions on a single charge, versus the overall lifespan of its battery is critical. Users must consider both to ensure their device remains reliable over time and within specific periods of use.

Higher capacity batteries offer prolonged periods of uninterrupted use, enabling users to venture further, or engage in activities for longer without concern for recharging. However, this can sometimes mean a trade-off with increased weight or size of the concentrator, potentially impacting its ease of transportation.

Oxygen Flow Settings


Customising oxygen flow settings is a key strategy in managing a concentrator’s operational life. Learning about different oxygen flow settings involves understanding the mechanism through which portable oxygen concentrators deliver oxygen to the user. The settings determine the amount of oxygen output, which is measured in litres per minute (LPM). Here’s a detailed look at these settings:


1. Continuous Flow Settings


Continuous flow settings provide a constant supply of oxygen. The settings are typically adjustable, allowing users to receive a fixed rate of oxygen per minute. Continuous flow settings can range from as low as 0.5 LPM to as high as 6 LPM or more, depending on the machine’s capability. This setting is crucial for patients who need a steady stream of oxygen, including those who require supplemental oxygen while sleeping, as breathing patterns can slow or become irregular during sleep.


2. Pulse Dose Settings


Pulse dose settings, also known as intermittent flow settings, deliver oxygen in bursts at the onset of each inhalation. Many portable models use a bolus method to release a set volume of oxygen each time the user breathes in. This can conserve oxygen, making the device more efficient and extending the battery life. The pulse dose is often measured in settings from one to six, which corresponds to the size of the oxygen bolus delivered. Some advanced concentrators have more refined settings to better match the user’s breathing rate and depth.


3. Auto-Titrating Settings


Some portable oxygen concentrators come with sophisticated sensors and software that automatically adjust the oxygen flow to the user’s breathing pattern. These auto-titrating settings can detect changes in breath rate and deliver higher doses when breathing is shallow or rapid and lower doses during slower, deeper breaths.


4. Sleep Mode Settings


A few advanced portable concentrators offer a sleep mode setting that provides increased sensitivity and a softer pulse dose of oxygen that is designed to detect shallow breathing during sleep. This mode ensures that users continue to receive the right amount of oxygen even when their breathing patterns change as they enter different stages of sleep.


5. Exercise Mode Settings


Exercise mode settings are designed for users who require additional oxygen during physical activity. These settings deliver a higher flow of oxygen to accommodate the increased respiratory rate, ensuring that the oxygen saturation level remains stable during exertion.

Higher flow settings equate to increased oxygen consumption and a corresponding uptick in battery usage, reducing the time the concentrator can be used between charges. Conversely, lower flow settings can extend the duration of use but must be balanced against the user’s oxygenation needs.

When in consultation with their healthcare providers, users have access to help adjusting and fine-tuning airflow settings. Doing so will optimise a balance between their respiratory requirements and the desire to maximise the duration of their device’s operation.

Environmental Factors


The environment plays a vital role in the functioning of portable oxygen concentrators.

Concentrators Conditions such as extreme heat or cold, humidity, and altitude can influence the performance of a concentrator, affecting both its efficiency and battery life. It is of high value to be mindful of how these conditions may require adjustments in a device’s usage.

High altitudes can pose challenges, potentially requiring increased oxygen flow rates, which can deplete battery life more rapidly. Extreme temperatures can also affect battery performance – cold temperatures may reduce battery efficiency, while high temperatures can lead to a device overheating.

To alleviate the impact of environmental factors, users can take proactive steps such as shielding the device from direct sunlight, maintaining it within optimal temperature ranges, and adjusting flow settings as needed to compensate for environmental stresses.

User Activity and Mobility


User activity is a variable that significantly affects how long a portable oxygen concentrator can be used effectively.

The level of physical exertion can alter oxygen needs, with more strenuous activities generally increasing consumption and, in turn, reducing the duration of concentrator use.

Strategies such as pacing oneself during activities, utilising energy conservation techniques, and employing pulse dose settings when appropriate, can significantly help in conserving oxygen and extend the concentrator’s operational span.

Selecting a device that offers an optimal combination of battery duration, oxygen output, and portability is essential for accommodating a user’s mobility needs while acknowledging the technical limitations inherent in portable oxygen concentrators.

Maintenance Practices


Maintenance practices are critical for the performance and longevity of portable oxygen concentrators. By following a routine maintenance schedule, users can ensure their devices operate efficiently and reliably over time.

Regular maintenance is paramount for the optimal functioning of portable oxygen concentrators. It prevents the build-up of contaminants and ensures all components work effectively. Neglecting routine care can lead to reduced oxygen purity, diminished performance, and the potential for device failure. Regular maintenance also identifies minor issues before they escalate into major problems, potentially averting the need for costly repairs or replacements.


Guidelines for Cleaning, Filter Replacement, and Overall Care




Most devices require regular cleaning of the exterior with a damp cloth to remove dust and debris. The oxygen outlet and any surface that comes into contact with the user should be cleaned more frequently to prevent contamination.


Filter Replacement:


Portable oxygen concentrators have filters that need to be cleaned or replaced at intervals recommended by the manufacturer. These filters trap particulate matter and ensure the oxygen delivered is clean. Some devices have multiple filters, including external gross particle filters, which can be cleaned, and internal filters, which may require professional replacement.


Overall Care:


Battery contacts should be kept clean and free from corrosion. Cords and cannulas should be inspected regularly for any signs of wear or damage and replaced as necessary. The device should also be kept in a well-ventilated area to prevent overheating.

Diligent maintenance can substantially extend the usable life of a portable oxygen concentrator. By ensuring that all components are clean and functioning as intended, the device can operate at peak efficiency. This efficiency reduces strain on the device’s motor and batteries, which can prevent premature wear. It also ensures that the concentrator continues to produce oxygen at the prescribed concentration, which is critical for users who depend on precise dosages for their health.

Consideration of Supplemental Oxygen Sources


While portable oxygen concentrators offer unparalleled convenience and mobility, there are circumstances where supplemental oxygen sources become necessary. Exploring and understanding these options ensures that users have continuous access to oxygen, even when away from power sources or during periods of extended use.

Options for Supplemental Oxygen in Addition to Portable Concentrators:

  • Stationary oxygen concentrators – larger units that provide a continuous supply of oxygen and are suitable for home use.
  • Oxygen cylinders – pressurised tanks that store a finite amount of oxygen, useful for backup or travel.
  • Liquid oxygen systems – can store oxygen in liquid form at very low temperatures, offering a compact and portable solution with a larger oxygen supply.


Backup Oxygen Tanks in Extending Usage Duration


Backup oxygen tanks play a crucial role in oxygen therapy management. They serve as a reliable alternative when the primary portable concentrator runs out of power or requires servicing. For those who are dependent on continuous oxygen, having a backup tank can be a lifesaver in the event of a power outage or equipment failure. Backup tanks can also extend the duration of time spent outside the home, providing peace of mind for users when travelling or engaging in outdoor activities.


Tips for Planning and Managing Oxygen Supply for Longer Durations:

  1. Estimate Usage: Calculate the amount of oxygen you’ll need based on planned activities and the duration of time away from power sources or during travel.
  2. Carry Extras: Always carry extra batteries for your portable concentrator, and know the locations where you can recharge them if necessary.
  3. Understand Tank Durations: Familiarise yourself with how long your backup oxygen tanks will last at your prescribed flow rate and plan for additional tanks if required.
  4. Scheduled Deliveries: If using liquid oxygen or oxygen tanks, arrange for scheduled deliveries to ensure you never run low on supply.
  5. Emergency Plan: Have an emergency plan that includes contact information for your oxygen supplier and knowledge of local resources, such as medical facilities that can provide oxygen if needed.
  6. Travel Arrangements: When travelling, notify airlines, cruise lines, or other transportation services of your oxygen needs. Some airlines provide an in-flight oxygen service but require advance notice.
  7. Check Device Compatibility: Ensure your portable oxygen accessories, such as conservers or regulators, are compatible with backup tanks or other oxygen systems you might use.
