Portable oxygen concentrators (POCs) are a significant relief to people managing respiratory issues. They provide vital support to patients in need of supplemental oxygen. However, there is a growing debate about using these devices 24/7.

Not all patients require full-time oxygen supplementation. Continuous oxygen use, when not recommended, has side effects. It can lead to complications like oxygen toxicity or breathing inhabitation. 

Who Needs to Use Oxygen 24 Hours a Day?

People who need oxygen are those whose blood oxygen saturation falls below the standard rate. Many reasons can cause low blood oxygen levels. Mainly, a condition in the lung can cause reduced oxygen saturation.

However, a medical doctor is the one who can determine and approve the need to use oxygen 24 hours a day.

Medical Conditions that cause low blood oxygen concentration are:

  • Chronic Obstructive Pulmonary Disease (COPD)
  • Physical injury in the lung
  • Asthma
  • Pneumonia
  • Congenital heart disease
  • Pulmonary fibrosis (scarring in the lungs)
  • Emphysema
  • Sleep apnea
  • Collapsed lung
  • Pulmonary embolism (a blood clot in the lung)
  • Acute respiratory  distress syndrome (ARD)
  • Pulmonary oedema (fluid in the lung)
  • Persons with breathing difficulties due to high altitudes
  • Interstitial lung disease

How Portable Oxygen Concentrator Can Benefit Your Life

Before delving into how a portable oxygen concentrator can benefit your life, it's essential to recognize the role of these oxygen machines. They are opening boundaries and helping patients lead a quality life.

Here is how a portable oxygen concentrator can benefit your life:

1. It Enables Moving Around and Traveling.

POCs eliminate the concept of being 'chained to the machine' in oxygen therapy. You will have the liberty to move and travel wherever you want. Carrying an oxygen source conveniently, whether walking or using other vessels, is a fundamental freedom. 

Embracing an active lifestyle is achievable with a portable oxygen concentrator. You can use it while jogging, attending community functions, or working. Oxygen, thanks to POCs, is no longer the limiting factor.

2. Easier Access to Oxygen

POCs use cutting-edge technology to ensure that the oxygen flow rate levels remain constant per the settings. You will benefit from a reliable, uninterrupted oxygen supply. 

Traditional oxygen tanks need constant refills. With portable oxygen concentrators, this isn't a concern. The machine sucks in ambient air and filters it to deliver pure oxygen in real-time. You will no longer worry about oxygen tanks that run out and need a refill. 

3. Greater Comfort and Independence

The convenience and portability that POCs offer enhance the user's comfort. With reduced restrictions, you gain greater independence, impacting your emotional well-being and self-confidence. 

Because of the peace of mind, you will improve your overall quality of life. With a POC, you can continue having an active life.

Downsides of Using a Poc as Your Only Concentrator

Although POCs provide convenience, mobility and portability, they have some downsides. These portable oxygen units may not meet all patients' needs during oxygen therapy. They have limitations in terms of oxygen concentration and flow rates. So, they may not meet the needs of all patients, mostly during sleep or intense physical activities.

Here are the downsides of using a POC as your only concentrator:

1. Limited Oxygen Output and Flow Settings

POCs have limited oxygen output and flow rate levels. It makes them less suitable for patients in need of high oxygen levels or those with severe lung disease. You need to understand this downside when choosing specific individuals.

  • Unsuitable for high oxygen output needs

High-performance POCs can provide continuous flow rates or pulse doses of up to 5 litres per minute (LPM). However, some patients' oxygen needs can exceed 10 LPM or higher. In such cases, stationary oxygen concentrators or liquid oxygen systems are the most appropriate.

  • Not ideal for severe lung diseases

A POC may not be the best choice for patients managing a severe lung disease. Such patients require more consistent flow rates and large oxygen volumes. Thus, while a portable oxygen concentrator may meet COPD patients' needs, it may not work well with individuals with severe respiratory conditions.

2. It Costs More Than You Think

The initial cost of a portable oxygen concentrator is high. Depending on the model, POC prices range from $800 to above $3,000. However, they provide a worthwhile investment over time because of their numerous benefits.

  • High Initial Cost

POCs have a higher upfront cost than other oxygen delivery systems. The reason is their advanced technology and the convenience they offer. The high price is a downside if you work within a tight budget. You must carefully plan your finances while exploring other purchase options or rental services.

  • More Costly Than Traditional Oxygen Tanks

Compared to traditional oxygen tanks, portable oxygen concentrators are more expensive. However, POCs promise longer-duration cost savings because they eliminate the need for refills. It's a factor you need to consider depending on the duration of the therapy and financial capabilities.

  • Servicing Costs Are Higher

POCs need annual manufacturing service, and parts like sieve beds need replacement after set hours of use. For example, the SimplyGo portable oxygen concentrator from Philips' Respironics sieve beds needs replacement after 500 hours. The cost can run up to $400.

3. Sound Levels

Usually, the sound levels of POCs are manageable, but they can still impact user comfort. The noise may be uncomfortable in quiet environments or when you need total concentration. 

The POC compressor that concentrates oxygen produces sound during operation. The decibel levels vary among models. Some POC models produce as low as 40 decibels. Audible operational noise may draw attention and also cause self-consciousness.

Downsides of Using a Poc as Your Only Concentrator

Selecting the appropriate POC for long hours of use is crucial, as it contributes to your well-being. However, it is essential to note that a portable oxygen concentrator should be used only with a medical professional's prescription. Your respiratory therapist will determine the best POC per your oxygen requirements and overall health. 

The factors to consider when choosing a POC are that you need to use it for long hours and during sleep.

Flow Rate

A POC flow rate capability determines the oxygen supply to a patient. The measure for oxygen output is in liters per minute (LPM). Portable oxygen concentrators can deliver flow rates above 3 LPM to 5 LPM. Other oxygen systems may flow rates above 5 LPM to above 10 LPM.

The device you choose should enable flow rate adjustment according to your needs. Patients with minimal stable oxygen levels may opt for devices with low flow rates. If you have a severe respiratory condition or hospitalization, you need a device with higher output.

We advise selecting a POC with a higher flow rate than your needs. It will come in handy during unexpected situations. Look for a portable oxygen concentrator that supports both continuous and pulse dose flow rates during the day and during sleep.

Power Consumption

For portable oxygen concentrators, they use rechargeable batteries. Choose a model with extended battery life and shorter charge time.

We recommend having charged backup batteries for use outdoors. During sleep, use your device while charging.

Portability

POCs are ideal if you often have an active lifestyle away from home. The devices use rechargeable batteries that are both AC and a car charger. They provide freedom and flexibility of use in different situations. 

Consider a portable oxygen concentrator with a higher capacity than your needs. Look for a lightweight model that will be easy to carry around. However, patients needing high oxygen output should opt for a home stationary concentrator.

Oxygen Concentration

The need to use a portable oxygen concentrator for long hours stems from oxygen requirements. You should consider and match your supplemental oxygen prescription to the device's specifications.

Typically, oxygen concentrators output between 87-99 percent pure oxygen. The level is similar to oxygen cylinders. Patients with chronic respiratory conditions requiring higher oxygen concentration should choose options that supply elevated oxygen levels.

Noise Level

The noise level of a POC depends on its size, power capacity, and weight. Portable oxygen concentrators that use higher power ratings and deliver more volumes may generate more noise. 

Smaller devices with lower flow rates and low power usage are generally quieter and generate less heat.

Warranty and Technical Support

Choose a device with more warranty years. It shows the manufacturer's confidence in the functionality of his product. Most POC models have a warranty of 2-3 years. 

You should purchase a device where the supplier provides technical support locally or through a trusted third party.

Affordability

Your financial capability will also play a role in determining the POC you choose to use for long hours. However, you should not compromise your health over money. You can look for alternative ways of accessing a POC, like Medicare or Medicaid. 

Talk with your supplier for financing options in which you can pay for your device through instalments. You can also look for an affordable portable oxygen concentrator for use 24/7 from ReadyO2.

Why We Do Not Recommend Using a POC as Your Only Oxygen Concentrator

Portable oxygen concentrators play a vital role in oxygen therapy. However, POCs are best used as a supplemental oxygen source rather than your main oxygen machine.

Reasons why we do not recommend using a POC as your only oxygen concentrator are:

  • A POC may not work well in some situations. Like when you need large oxygen volumes.
  • Some POC may fail to have adjustable flow rates, making them unsuitable for sleep.
  • Prolonged use of a POC leads to overheating, which can compromise oxygen output levels.
  • You need a back system for use during service and repairs due to malfunction or breakdown.
  • A POC literary is not a workhorse. The device is a secondary option for easing the mobility of oxygen patients.
