In order to qualify (or re-qualify) you for oxygen, we must be able to document the need for it.
We will monitor your oxygen saturation first with no additional oxygen and, if need be, we may ask you to walk or exercise for a short period of time if indicated.
If your oxygen level drops below the established level, we will place you on oxygen and insure you can maintain an appropriate saturation level.
The test takes 30 minutes.
