A year ago, Lyn underwent an oximetry test before being placed on oxygen at night. Her results were so low, she was at risk of passing away in her sleep at any time. She's been on oxygen for a year now, using an oxygen condenser while she sleeps. She was not put on a CPAP machine because she would not agree to a sleep study and the specialist did not believe a mobile sleep study would be sufficient.
Last night, Lyn had to go through the oximetry test again. It was necessary because she has to be recertified as needing oxygen during sleep. She was not happy to know that she had to submit to the test. Yes, The Look came out in full force. Fortunately, the test is pretty unobtrusive. She just had to have one finger gently clamped into the oximeter's sensor. She was not allowed to sleep with oxygen on because it would defeat the purpose of the test.
We should know shortly what the results are and if she is recertified to continue using the oxygen condenser.
