What Are Some Top Pulse Flow Oxygen Concentrators?

by Stephanie Greco

When someone is just beginning to discover oxygen concentrators and all of their benefits, they may encounter two different kinds of oxygen concentrators that offer different types of treatment styles. Namely, these two types differ in how they provide the dosage of oxygen and are known as pulse-flow oxygen concentrators and continuous-flow oxygen concentrators.


The names given to these oxygen concentrators derive from how they administer the oxygen that the patient needs. In continuous-flow oxygen concentrators, oxygen is delivered continuously or without the need for it to be activated by inhalation. In pulse flow oxygen concentrators, the therapy is “activated” once the person that is using the oxygen concentrator inhales. If you are interested in learning more about pulse flow oxygen concentrators and some of their benefits from O2 Assist, do not hesitate to continue reading below. 

Differences Between Pulse and Continuous-Flow Oxygen Concentrators

As mentioned above, the most important difference between these oxygen concentrators lies in how they give patients the oxygen that they need to live their regular lives. A continuous-flow oxygen concentrator will deliver oxygen no matter if the patient is breathing. This means that the oxygen concentrator will use more energy to help the patient because it will always be running. This is an important consideration to have in mind should you need to be conscious of the amount of money that having an oxygen concentrator would cost you during your monthly electric bill.


Another difference that pulse and continuous flow concentrators have is the intensity of treatment that they offer. Continuous flow concentrators offer a much more intense style of treatment because of how often it administers oxygen to patients. On the other hand, pulse flow concentrators are the best option to be used by those that do not need such intense treatment.
