Consider Your Portable Oxygen Concentrator Battery Options

Leaving your Inogen One® G3 plugged in past the full charge time will not harm the concentrator or the battery. WARNING It is the responsibility of the patient to periodically check the battery and replace as necessary. Inogen assumes no liability for persons choosing not to adhere to manufacturers recommendations.

Most people must use supplemental oxygen for at least 15 hours every day. Some people need to use it 24 hours a day. A healthcare provider will direct you on how often to use it and what your output setting should be. If you have a short-term condition, you may only need an oxygen concentrator until you recover.

Symptoms include pleuritic chest pain, substernal heaviness, coughing, and dyspnea secondary to tracheobronchitis and absorptive atelectasis, which can lead to pulmonary edema. Pulmonary symptoms typically abate 4 hours after cessation of exposure in the majority of patients.

Many of the side effects experienced with an oxygen concentrator may be experienced with a CPAP machine. Patients may have morning headaches, dry mouth or nasal irritations from the mask or nasal cannula. Frequent use of the mask or nasal cannula can also lead to skin irritations from the mask contact.

Medicare covers portable oxygen concentrators, including Inogen, for beneficiaries who qualify under Medicare rules. Inogen is covered as durable medical equipment under Medicare Part B. Medicare may cover Inogen portable concentrators for enrollees with COPD, pneumonia and other lung conditions.

You will have to regularly change your replacement columns to keep your G4 in working order. Inogen recommends that you change your replacement columns every 18 months to 2 years, however, that is all dependent on the climate you live in, how often you use your concentrator, and if you store your concentrator properly.

Oxygen concentrators are made in such a way that they can run for 24 hours. But at times, they face the problem of heating up and stopping abruptly. Therefore, after continuous usage of 7-8 hours, the concentrator should be given a rest of 20-30 minutes.
