Differences between Oxygen Concentrator and Oxygen Cylinder

what are oxygen concentrators and oxygen cylinders? 

In recent times, oxygen cylinders and oxygen concentrators have become prominent due to their crucial role in providing supplemental oxygen to COVID-19 patients and individuals with respiratory difficulties. However, it is essential to note that these devices have been used for several years to treat various medical conditions.

Let’s explore the details of oxygen cylinders and oxygen concentrators to understand their functionalities and critical differences.

An oxygen cylinder, also known as an oxygen tank, is a storage device that contains compressed liquid oxygen. The oxygen from the cylinder is delivered to the user through an oxygen mask or cannula. It provides a finite amount of oxygen and requires refilling when the supply runs low.

On the other hand, an oxygen concentrator operates differently. It filters and concentrates oxygen molecules from the surrounding air, providing an infinite supply of oxygen. Like an air-conditioner, it intakes ambient air, extracts and purifies the oxygen, and delivers it to the user. Unlike an oxygen cylinder, an oxygen concentrator does not need refilling and can continuously provide oxygen as long as it is powered.

There are two main types of  oxygen concentrators available:

Continuous Flow Concentrators: These devices deliver a constant flow of oxygen to the user, which remains consistent until the concentrator is turned off or adjusted by the user or healthcare professional.

Pulse Concentrators: Pulse concentrators are designed to supply oxygen based on the inhalation and breathing patterns of the user. They detect the user’s breath and release oxygen accordingly. This ensures oxygen delivery when needed, optimizing oxygen usage and conserving energy.

Both types of oxygen concentrators offer convenience and portability, allowing individuals to receive oxygen therapy in the comfort of their homes or while on the go.

Oxygen Cylinder And Oxygen Concentrator Use At Home 

Besides COVID, several conditions cause a person’s oxygen levels to fall below the desired normal levels. Some of these conditions include:

  • Asthma
  • COPD
  • Lung cancer
  • Flu
  • Pulmonary fibrosis
  • Congestive heart failure
  • Chronic bronchitis

When either of these conditions causes oxygen levels to fall below 94%, an oxygen cylinder for home use is the best choice. This device also works, albeit as a temporary measure, when a patient’s oxygen levels fall up to 85%. 

You need a doctor’s prescription to use either a concentrator or oxygen cylinder at home. You will be prescribed a cylinder for home-use when you need oxygen only for short periods. On the other hand, a home use oxygen concentrator machine will be prescribed when you need supplemental oxygen throughout the day even while sleeping. Besides these things, other factors that determine the choice of the best oxygen concentrator or cylinder include the amount of oxygen you need, the size and layout of your house, your daily activities, and your personal preference. 

Here are some things to keep in mind while using a home oxygen concentrator or cylinder:

  • Always settle for the best quality oxygen cylinder near me. Studying the features, quality, and after-sale service pays in the long run. 
  • Keep a check on your oxygen saturation levels through a pulse oximeter.
  • There has to be a match between your oxygen requirement and the production capacity of the oxygen concentration near me. Ideally, the device that you buy must have a higher capacity than your requirement.
  • Don’t use these devices near a flame or while smoking.

For the most important factor to consider while using an oxygen cylinder or concentrator for home use, if you feel any changes in your breathing patterns or your symptoms seem to get worse, contact your healthcare practitioner at the earliest. 

Price Difference Between Oxygen Cylinder And Oxygen Concentrator 

In addition to the factors mentioned earlier, the price of the devices is a significant consideration when choosing between an oxygen concentrator and an oxygen cylinder. Initially, the cost of an oxygen concentrator may appear higher than a cylinder’s. However, an oxygen cylinder tends to be more expensive in the long run. This is due to the need for frequent refills, while an oxygen concentrator utilizes ambient air and only requires electricity to operate, making it a low-maintenance option. The main ongoing cost associated with an oxygen concentrator is electricity consumption.

Furthermore, the cost of a portable oxygen concentrator is often higher than a stationary one. Still, it offers the advantage of mobility and enables individuals to engage in outdoor activities without constraints.

For those who prefer to avoid investing a significant amount of money upfront or have a short-term requirement, renting an oxygen cylinder or concentrator is a viable option. Renting helps save costs and provides a hassle-free experience, as the rental company is responsible for maintenance and replacement expenses.

It is essential to carefully consider the upfront and long-term costs and personal needs and preferences when deciding between purchasing or renting an oxygen concentrator or cylinder. Consulting with healthcare professionals and rental companies can provide valuable insights to make an informed decision based on individual circumstances.
