Can You Tell If She's Breathing?

Why don't child monitor's have pulse-ox functions?

I mean, this is pretty basic nowadays.  Even without taping the reader to a finger or a toe, the machine could measure the CO2 output in the room to let you know that your child is sleeping...and alive.  

Or it could just count the number of respirations as your child's chest moves up and down.

These are not new functionalities.  They've just never been properly applied to home-safety.

Instead, the current "recommendations" are stupid things like the advice I got from the doctor when my daughter was ill:

"You should check on your child every 2 hours to make sure that they're not having trouble breathing"

Uhm....

2 HOURS!?!?  

The brain only lasts 4 minutes without respiration providing oxygen.  Wouldn't it be better if we just had the breathing monitored by our child monitor?  A little alarm goes off if the CO2 levels increase too much..or don't decrease fast enough...or that it can't count your child's respirations?

I mean, seriously!  People who make baby products- where are your heads!?  You'd rather provide the ability to download pictures from the baby cam than something useful like knowing that your child is breathing.
