One of the most common questions amongst users or those who are interested in buying a portable oxygen concentrator is: will the length of tubing influence oxygen concentration during use?
The answer: yes and no. This comes down to the type of machine you are using.
Pulse machines are affected by the length because there is not a steady flow constantly pushing the air through the tube. While the air is moving through the length of the tube, it is fighting against friction the entire time. The length will depict how much the air is truly affected. For someone who is using a portable oxygen concentrator, the length of the tube is generally short, so the length will not have any significant effect on a pulse machine or continuous flow portable.
Continuous flow machines are recommended for those using a longer tube at home. Think of your longer tube length as a hose. If the water pressure is constantly the same, that’s how it will be for the entire length of the hose. The same can be said for oxygen concentrators. Regardless of the length, as long as there is a continuous flow, oxygen concentration will not be affected. Once again, if you are using a pulse flow, the oxygen concentration will be affected because there is not a constant push coming from the machine.
