Conducting scientific researches and publishing clinical data is necessary for Medical devices company. Such research findings will help the company improve their products and help to prove their promises on product performance.

Among all the Portable Oxygen Concentrators manufacturers in the market, Inogen has undertaken several scientific researches specific to their products. They have conducted the study and published the clinical data of the same.

Some of the Inogen researches and the their findings are mentioned in Inogen catalogue:

1. Stegmaier JP. Chatburn RL, Lewarski JS. “Determination of an Appropriate Nocturnal Setting for a Portable Oxygen Concentrator with Pulsed-Dosed Delivery.” Abstract.
   Respir Care November 2006;51(11): 1305.
   Summary: The purpose of this study was to determine if a single titration of oxygen using a POC during ambulation/exercise would provide an appropriate setting for nocturnal use. The results suggested that an oxygen setting selection based on daytime ADL/ambulation appears to produce effective nocturnal oxygen therapy as evidenced by a mean sleeping SpO2 of 92% and no clinically significant desaturation.
2. Chatburn, R, Lewarski J, McCoy R. “Nocturnal oxygenation using a pulsed dose oxygen conserving device compared to continuous flow oxygen.”
   Respir Care March 2006;51(3): 252-256
   Summary: The study compared nocturnal oxygenation with continuous flow versus the Inogen One among a group of established LTOT users with chronic lung disease. The results demonstrate that when appropriately titrated, the Inogen One is essentially clinically equivalent to continuous flow oxygen. The study also suggests that daytime pulse dose titrations may be effective in determining nocturnal oxygenation.
3. Case, R, Hausmann R. “Use of a portable oxygen concentrator with a fixed minute volume oxygen conserving device to deliver oxygen to exercising pulmonary rehabilitation patients.” Abstract.
   Respir Care November 2005;50(11):1510.
   Summary: The study concluded that the Inogen One was as clinically effective as continuous flow oxygen at maintaining target SpO2 levels in high flow (4-5 lpm) oxygen users during intense exercise.
4. McCoy, R, Lewarski, J. “A test for clinical equivalency: A portable concentrator with integrated oxygen-conserving compared to continuous flow oxygen during nocturnal use.” Abstract.
   Respir Care November 2005; 51 (11):
   Summary: This study demonstrated the Inogen One TM POC was able to deliver adequate nocturnal oxygen therapy as evidenced by continuous SpO2 monitoring in 9 of 10 (90%) of patients studied. The resting daytime oxygen titration and the resultant SpO2 appears to be reasonably effective method for determining an appropriate nocturnal oxygen setting.
