Choosing a Portable Oxygen Concentrator

portable oxygen

The most important factor to look for in a POC is its ability to provide adequate supplementary oxygen, which is necessary for the relief of hypoxia or oxygen deficiency. A POC should be flexible enough to adjust the amount of oxygen delivered according to the patient’s breathing cycle. Other factors to consider when choosing a POC include its maximum oxygen purity, number of settings for adjusting oxygen flow, battery capacity, add-on batteries, and power cord options.

Pulse flow

The Pulse Flow Portable Oxygen Concentrator provides continuous oxygen to a patient’s mouth and nose. The oxygen delivered to these areas is purified and can be used for a variety of uses. The unit also features a built-in nebuliser to help those with a chronic condition breathe more easily. The concentrator can run on battery power, which is very convenient for the user, as the concentrator can run for as long as 13 hours without needing a recharge.

The AirSep Focus weighs just over two pounds, about half as much as other comparable portable oxygen concentrators. It is not suitable for all-day use, but is best for short walks or occasional use. It also boasts a one-and-a-half-hour battery life, which is better than other portable oxygen concentrators. You can also purchase additional batteries that can be interchanged with the included ones.

The Medical Pulse Flow Portable Oxygen Concentrator provides up to 5L of concentrated oxygen for up to three hours. Previously, only the medical community could use them. With the availability of this product, it has become more affordable and available to the general public. The device is simple to use and rechargeable, and the display shows you how much oxygen is left in the tank. It also displays the flow of oxygen and its concentration.

A pulse flow portable oxygen concentrator should be chosen carefully based on the amount of oxygen it can deliver to the patient. A continuous flow concentrator is not suitable for high oxygen requirements. One must choose a portable oxygen concentrator with the right output and maximum outlet pressure. The oxygen concentrator must also be able to work at higher altitudes. You should also check the operating altitude of the concentrator to be sure it meets the needs of the patient.

Continuous flow

One of the biggest differences between pulse dose and continuous flow portable oxygen concentrators is the type of oxygen the concentrators produce. Pulse dose units have a lower flow rate and are used when an individual needs oxygen continuously but does not want to be inhaled. Continuous flow portable oxygen concentrators, on the other hand, produce a continuous stream of oxygen and are therefore less powerful. They also tend to be larger and have larger compressors, so they probably produce more oxygen waste than pulse dose concentrators.

Both modes deliver oxygen in pulses triggered by inspiration. Therefore, establishing equivalence between POCs and CFOs is difficult. For this study, we used mathematical modeling and bench measurements to compare a POC with a CFO. We estimated FiO2 levels in the trachea and acini to estimate the fraction of inspired oxygen delivered in each mode. We also measured the variability of the two modes using data from a clinical trial.

Pulse-dose portable oxygen concentrators, on the other hand, are a great option if you travel frequently. Pulse-dose concentrators are ideal for long-distance travel. Pulse-dose concentrators are more convenient to use, so they can be taken anywhere. Pulse-dose concentrators are generally more expensive, weighing around 25 pounds and are intended for home use.

Pulse-flow concentrators are small and lightweight, and can be easily carried in a backpack or shoulder bag. Continuous flow concentrators are much heavier and require a two-wheel frame for transportation. Some units are small enough to carry in a car power port or wall outlet. The average watt usage of a portable oxygen concentrator is shown on a chart below. The lowest power consumption of an oxygen concentrator is found in the SimplyGo. The second lowest is the iGo, while the third lowest is the Zen-O.

Liquid oxygen system

The liquid form of oxygen is stored in a tank at hospitals. While most hospitals use liquid oxygen, the local gas supplier may store oxygen in a tank at their facility and convert it to a gas that can be used in a portable oxygen system. A local gas supplier can also deliver LOX and the cylinders to the patient. There are several benefits of liquid oxygen. It is less expensive than compressed gas and is available in more places.

In recent years, the use of liquid oxygen in medical facilities has increased dramatically. The National Fire Protection Association has established basic requirements for the storage, use, and transfer of liquid oxygen in health care facilities. The standard, which was published in 1999, is incorporated by reference into NFPA Standard 101, the Life Safety Code. The cylinders contain an oxygen gas that has undergone the process of vaporization. The system’s liquid oxygen reservoir can accommodate up to 20 liters of oxygen, and a high-flow cylinder can accommodate up to 15 lpm.

Another advantage of a liquid oxygen portable is its portability. Its lightweight design allows the user to carry the unit wherever they go. It can be refilled from a reservoir. The medical liquid oxygen provider can refill the tank every three weeks. Because liquid oxygen does not require electricity, the liquid oxygen portable is better for areas with frequent electrical blackouts. The device also lasts a longer period of time, meaning it’s more convenient to carry on the road.

Home concentrators are also a great option for portable oxygen usage. These units are lightweight and robust and can be worn on the back or pulled behind the car. They require a seven-foot oxygen tubing. A portable concentrator recharges in the car, and the tube itself is lightweight and easy to clean. Its compact design and removable battery can make it easy to carry anywhere. Most portable oxygen systems also allow for easy charging and don’t require refueling.


Purchasing a portable oxygen concentrator is the best way to get the benefits of a medical device without sacrificing portability. Portable oxygen concentrators can either be powered by an external AC or DC power source, such as a car battery, or by using a wall outlet. The weight of the concentrator unit should be considered when choosing a portable oxygen concentrator. Some models may also have a battery for extended use, which is ideal for people who are on the go and do not wish to recharge it often.

The weight of portable oxygen concentrators differs from wearable POCs. While wearable POCs are smaller and weigh around five pounds, transportable oxygen concentrators can weigh up to 20 pounds. The TOC, on the other hand, can provide continuous flow of oxygen. Because of its weight, TOCs place a heavy burden on the oxygen user. Patients with COPD rarely use continuous flow during ambulation.

Weight of portable oxygen concentrators varies based on size and weight. The portable oxygen generator unit 3 may have a shoulder strap or carry handle to allow it to be easily transported. The device itself is also lightweight and may be carried on a wheel cart. However, there are many other ways to transport portable oxygen concentrators. They can be positioned on a wheel cart or a specialized cart, depending on their size and weight.

Advanced portable oxygen concentrators have become essential for long-term oxygen therapy (LTOT). Improved therapy compliance has been linked to improved patient outcomes, which means patients are living longer and healthier lives with the help of this technology. POCs are now the fastest-growing segment of the oxygen therapy market. They have double-digit growth, especially when it comes to the lightest and most compact versions. The market for portable oxygen concentrators is expected to grow by nearly 20 percent in the next five years.

Battery life

Many people will ask, “How long does the battery life of a portable oxygen concentrator last?” This is a question that is particularly important if you’re a frequent traveler. While most portable oxygen concentrators last up to eight hours on a full charge, some travel modes can prevent you from plugging your concentrator in to recharge it. It’s best to plan ahead and choose a concentrator with enough battery life to last for 1.5 times the duration of your flight.

Depending on your level of need, you might have to recharge your portable oxygen unit several times a day. Generally, this means that your battery is used up sooner than you would expect. It’s possible to extend battery life to as much as six hours by simply plugging the unit into an outlet. However, it’s unlikely that you’ll use it all at once. To avoid this problem, consider buying a smaller model with a higher battery life.

Modern portable oxygen concentrators have advanced battery technology in recent years, and this improved the overall battery life significantly. Some models can be recharged using a cigarette lighter outlet and even offer sleep mode technology. In addition, many POCs now have audible alarms for when the battery needs to be recharged. Using oxygen at prescribed settings is safe and does not pose any additional risk to the user. In addition, some units even offer extra features, like a rechargeable external battery.

Another feature that improves battery life is the ability to set an upper limit on oxygen flow. Inogen One G5 concentrators can reach a maximum flow of 80 cc, but their batteries can run down quickly. Consider a double battery to ensure you never have to wait for the battery to charge completely. This feature is an important feature for those who travel frequently. It is also worth considering if you’ll need to use higher flow settings frequently.
