COMPARISON OF THE HELIOS PORTABLE OXYGEN SYSTEM DOSE SETTING TO THE SPIRIT PORTABLE OXYGEN SYSTEM DOSE SETTING WITH EXERCISING PATIENTS



Robert McCoy, BS RRT, Valley Inspired Products, Burnsville MN

Long term oxygen therapy patients are receiving oxygen earlier in their disease. These patients are younger and more active than in the past and are requesting longer lasting, lighter systems. The Helios portable oxygen system was introduced in 2000 and has become one of the most popular portable systems due to its light weight (3.5 lbs) and long operating time. Recently, home care providers and patients have commented that the Helios cannot maintain oxygenation for some patients. The Spirit portable oxygen system has been introduced in 2003 and has a similar weight, yet a higher dose per setting. The objective of this evaluation was to determine if the dose per setting had an impact on patient oxygenation with exercise.



Method: Five patients were selected from the local ALA lung club that were using the Helios portable, active and agreeable to this evaluation. One patient was unable to complete the two product comparison and was dropped from the study. The patients were asked to walk on a treadmill for 10 minutes at their prescribed setting then walk on the treadmill at the same speed and grade for 10 minutes at the same setting on the Spirit. A Nonin oximeter (Palmsat 2500) was used to collect Sat. and HR data. Respiratory rate was counted manually. 

RESULTS: Each patient had a higher average saturation on the Spirit compared to the Helios at the same setting. Each patient had a higher average HR on the Helios compared to the Spirit. Respiratory rate was, on average, slightly higher on the Helios compared to the Spirit.

CONCLUSION: Dose volume is different between the Helios and the Spirit at similar settings. This dose volume has an impact on patient oxygenation and requires the physician and therapist to understand the capabilities and limitations of each system. If the maximum dose setting on a portable oxygen system cannot properly oxygenate a patient, an alternative system should be utilized.
