Portable oxygen concentrators are not a small investment, making sure you choose the right one for your needs is very important. With so many to choose from how do you know which one is right for you. The most important feature in travel oxygen concentrators, is the flow. Oxygen Units such as the Respironics Evergo and The Invacare XPO2 are pulse flow units. Continuous flow units would include the Sequal Eclipse 3 and the DeVilbiss IGo.
Pulse vs Continuous Flow
Many patients receive there oxygen in pulse flow also known as on demand flow, which means the oxygen does not continuously flow through the hose. Instead, the oxygen pulsates coming out as you take a breathe. The strongest pulse flow portable oxygen concentrator is the Respironics Evergo. The Evergo puts out up to 1050 mils of oxygen compared to the XPO2, which only puts out 750 mils of oxygen at max. Pulse flow travel oxygen machines have settings usually between 1-6. Settings on a pulse flow oxygen machine are different than on a machine that flows continuously. On demand delivery may be a different amount of oxygen on a setting of 3 depending on the unit you are using.
Most patients that needed continuous flow oxygen were not able to travel until the Sequal Eclipse came on to the market. Up until last week, the Sequal Eclipse was the only continuous flow portable oxygen concentrator that has both a continuous and pulse flow setting. Today, there are now 2 other units that have the same settings, the Oxlife Independence and the DeVilbiss Igo. Heavier and bulkier than most of its competitors, the continuous flow units include a light cart for easy transport. Best off all, because of its ability, through the power and the continuous supply of oxygen-mode, the continuous flow oxygen units are good for both travel and home, making the need for massive home oxygen cylinders or concentrators obsolete.
