I have Sleep Apnea and I have found that using the CPAP Machine has greatly helped my quality of life, however I am concerned about no battery backup when the electricity goes out. We are encouraged to make sure we have a tight seal. I recently woke during the night feeling like I was smothering. I took off the mask and was gasping for air when I realized the electrical power was out and no air was flowing through the machine. This was very scary ! I wonder why there are no safety regulations requiring battery backup for when the electrical power goes out.
