Holding breath

I have Sleep Apnea and also Awake Apnea. I hold my breath for long periods of time while asleep and awake. My CPAP machine takes care of the Sleep Apnea problem but my Doc tells me there is nothing to ensure I breath while awake. Often my wife tells me to breath or my brain kicks in and tells me my body needs oxygen. They make units for babies cribs while the infants are asleep to let parents know the infant has stopped breathing and that is absolutely wonderful. My question is that there are probably tens of thousands if not more that suffer from Sleep Apnea and also stop breathing while awake. Why can't they make a device that comfortably fits on the chest with a strap or some other means that monitors breathing using the same technology that detects a baby breathing (chest expansion-contraction, sound, etc.) and let off a low beep or vibrate (cell phone technology) that tells an individual to breath? THis would certainly extend a persons life and improve a persons energy level as does the CPAP machine.
Just a thought.

I suggest to buy a pulse oximeter with an alarm (like CMS oximeters, not necessary recording). It will beep every time your SpO2 is low
