Pulse and Continuous Flow Oxygen Concentrators

What’s the difference between Pulse and Continuous flow oxygen concentrators? How do they work? How should you choose one over the other? Read on to learn about the different options available to you. And if you’re still unsure, ask your doctor! It’s very likely that he or she can recommend one that’s best for your specific situation. Here are some things to consider before buying a concentrator.

Fixed minute volume technology

Fixed minute volume (FMV) oxygen concentrator technology has been designed to deliver the proper amount of oxygen for the person’s needs. Its highly sensitive design automatically adjusts the flow of oxygen to match the user’s breath pressure. This technology is the “gold standard” in oxygen therapy, and it is proving to be extremely popular among patients with a variety of medical conditions. But what exactly is FMV? It’s a complex technology, but it works by detecting the person’s breathing patterns, and triggering an appropriate bolus dose based on the fixed minute volume.

Compared to traditional compressed oxygen tanks, portable OCs can provide mechanical ventilation in austere locations. During an evaluation, an ultraportable OC was paired with an impact 754 ventilator, delivering a fraction of the inspired oxygen to evaluate lung function at altitudes of 1,200 to 6,500 feet. During the trial, FiO2 remained higher than 0.7 at minute ventilations between three and six L/min.

Although a number of POC technologies have been developed over the years, some are still in experimental stages. While a fixed minute volume oxygen concentrator is the most effective way to deliver oxygen, its reliability is questioned by some experts. While continuous-flow POCs are more reliable in detecting inspiratory flow, they are not yet able to differentiate between a patient’s quiet breathing and vigorous breathing. Further, nasal geometries and suboptimal positioning of the cannula can lead to an inability to accurately detect inspiratory flow during a patient’s quiet breathing.

Fixed dose administration

The use of an oxygen concentrator is associated with better outcomes for patients with respiratory diseases. This device helps to increase oxygen saturation and improve mental attentiveness and stamina. Patients who use oxygen concentrators also have better mood and improved cognitive performance. In addition, patients with COPD have reduced survival rates than those who use concentrators only during nocturnal hours. However, individual patient testing is necessary to determine which oxygen delivery system is most suitable for their condition.

Two main types of POCs are available: continuous and pulse flow. Continuous flow units give out a specific adjustable dose, measured in litres per minute. Pulsed units pulse air through a cannula with each breath. The size of each pulse determines the output. However, continuous flow units have many benefits over pulse units. They are more affordable and easier to use. However, there are some cons associated with using one.

An automatic oxygen flow regulator has been developed for the purpose. It is capable of adjusting the flow of oxygen according to the intensity of physical activity. This mechanism was introduced to prevent abrupt changes in oxygen flow. As a result, oxygen flow increases when the patient becomes more active, and decreases when the patient is less active. This automatic dosing device can be switched off and used manually if needed. This mode also prevents the risk of patients falling into a moderate or severe condition without a proper dose.

Pulse dosage administration

Continuous flow oxygen concentrators and their pulse dose modes provide two different kinds of oxygenation patterns. Pulse dose mode produces oxygenation patterns with cyclic behavior characterized by high and low FIO2 periods. The FIO2 spike on the oxygen concentrator’s display verifies that the pulse was administered at the programmed time. In a nutshell, the different modes are designed to provide different levels of oxygen.

In addition to continuous flow oxygen administration, pulse dosage oxygen concentrators offer full independence. Users don’t have to refuel the oxygen tank or transport the oxygen therapy machine to their home. The device also doesn’t require complicated settings. Simply switch on the device and adjust the flow level. Then, you can breathe normally. There are also some pulse dosage concentrators that are compatible with liquid oxygen tanks.

One advantage of pulse dosage oxygenation is its ability to maximize the amount of oxygen available in the active respiratory space, which can be a valuable commodity under far-forward conditions. In addition, pulse dose oxygenation prevents supplying “superfluous oxygen” to the anatomic dead space, where exchange is not possible. The oxygen delivered in this manner has the potential to be significantly higher than continuous flow.

There are some advantages and disadvantages to both types of oxygen administration. Pulse dosage oxygen concentrators are not always the best choice for everyone. While pulse dose machines work well for many patients, they are not suitable for people with specific medical conditions. And continuous flow oxygen concentrators are ideal for nighttime use, while pulse dose machines work well for daytime hours. There are also some advantages of continuous flow oxygen concentrators, but you should consult with your doctor before choosing one. Discontinuous oxygen concentrators.

Smaller units

The difference between pulse dose and continuous flow oxygen concentrators can be summed up in two words: convenience and price. Pulse flow oxygen concentrators use a nasal cannula to administer a small amount of oxygen in the form of pulses. In contrast, continuous flow oxygen concentrators continuously pump oxygen into the body. Pulse flow oxygen concentrators use a smaller amount of oxygen and are more portable.

AirSep has a compact, lightweight unit, the Freestyle 3, which weighs only five pounds. Designed for active use, the Freestyle 3 is easy to carry around and boasts a low profile and a quiet pulse flow. It is portable and can be worn over the shoulder or converted into a backpack. It is also compatible with most common power sources, including USB and power adapters.

Another difference between continuous and pulse dose concentrators is the battery life. Portable oxygen concentrators are typically powered by batteries. Pulse dose concentrators typically use lithium-ion batteries, which are the same type used in common electronic devices. Increasing demand for oxygen therapy means that battery life will continue to increase. As such, choosing the right oxygen concentrator will depend on your specific needs and lifestyle.

Despite the obvious advantages of portable oxygen concentrators, they do have some drawbacks. While portable oxygen concentrators are more compact and lighter, they are not as powerful. Because they use a rechargeable battery, they are more expensive than portable concentrators. Furthermore, they need a power source. This can be in the form of an AC or DC power source. A rechargeable battery or AC power source will provide a constant flow of oxygen.

Battery life

When it comes to battery life for continuous flow oxygen concentrators, there are a few things to look for. Batteries are made to last for about 500 charge cycles, and are covered under warranty for three years. A good rule of thumb is to have enough power to use the concentrator for 1.5 times the duration of the flight. The battery life of a continuous flow oxygen concentrator is a crucial factor in its overall performance.

Portable concentrators are the most convenient choice, since they can be recharged by connecting to a DC jack in a car or hooked up to an AC outlet. Many portable concentrators offer up to 5 hours of continuous oxygen concentrating power on a single battery charge. Portable concentrators tend to run a little less on a single battery charge, so it is best to choose one that has a long battery life.

One brand of continuous flow portable concentrators has the highest total oxygen output of any other concentrator on the market, and it weighs only 18.4 pounds. This portable oxygen concentrator has a telescoping handle and removable cart. It runs on either a standard household AC or a DC automotive power supply, and a battery that recharges at 2.0 LPM is ideal for traveling. A portable oxygen concentrator is a great solution for those who require 24-hour support and are not able to stay at home. Battery life for continuous flow portable concentrators is an important factor.


There are several factors to consider when choosing the wearability of continuous flow oxygen concentrators. The most obvious consideration is battery life. Regular concentrators will last about four hours before requiring a recharge. Smaller concentrators will last about four hours while larger, heavier devices will last up to seven hours. If you plan to travel frequently, you may want to consider a device that has a built-in cart or flip-up handle.

Continuous flow oxygen concentrators are often noisy, so be prepared for some noise. While all devices generate noise while they are in use, some brands have attempted to reduce this noise. Before purchasing a continuous flow oxygen concentrator, consult your doctor for a prescription. Your doctor will be able to tell you how much oxygen you need and whether or not you should use it while sleeping. A high-quality unit will provide enough oxygen to keep you breathing well.

If you’re concerned about wearing a concentrator, the Oxlife Independence is a durable choice. The product has low repair and warranty claims and is a great option if you’re on the go. It comes with a five-year warranty, which is more than most competitors. You’ll also find newer models with DNA Technology. The oxygen concentrators communicate with the manufacturer to ensure proper performance.
