Passionate to Help Others

Respiration Nation has grown because of our passion to help people. It began while helping out a family member who needed portable oxygen. As I began my research I realized how confusing and intimidating the process was trying to understand all the different types of es, which one wmachinould suit him personally, and prices! I was absolutely blown away by how much a brand new machine cost, and had to go back to the drawing board. I had an "Ah ha" moment when I realized these machines last up to 25,000 hours! And that's when I started searching for gently used portable oxygen machines; buying only from smoke free homes, and all with 95% of their useful life left. My mission is get everyone who needs oxygen, on oxygen. For a fair price.

  • Why would someone need a portable oxygen concentrator?

    Portable oxygen concentrators are medical devices that can be used to deliver medical grade oxygen to individuals suffering from any kind of breathing related issues. These machines are beneficial to individuals that have oxygen levels lower than normal, and have also become extremely important for individuals who are suffering from symptoms of COVID-19.

  • Do I need to worry about my portable oxygen concentrator running out of oxygen?

    The answer is No! As long as there is a power supply or battery available, your portable oxygen concentrator will never run out of the required oxygen. These devices collect oxygen from the air and concentrates it so that it delivers 90% or more of oxygen to the individual. However, depending on usage every 12-18 months your portable oxygen concentrator may flash a signal to “replace columns.” DO NOT WORRY. Your portable oxygen concentrator will still concentrate oxygen for 30 DAYS! You can purchase sieve beds (columns) right off amazon, and it is a very easy step by step process. You can contact us, as we are always available to serve you, and we can walk you through the entire process.

  • How long do the portable oxygen concentrators last?

    All of our used portable oxygen concentrators have a useful life of up to 25,000 hours. We work really hard at making sure all of our inventory has 90% or less of its useful life available to you. That means all of our machines have 10% or less of usage in them, guaranteeing you a peace of mind purchase.
