| Now this
is the type of gadget that you'll definitely want to know about. It's called
a pulse oximeter, and it wraps around one of your fingers or toes. Don't
worry, it doesn't hurt at all. When it's turned on, you can see a red light
shining at the tip of your finger, just like the part in the E.T. movie
where E.T. phones home! Remember that great movie?
Anyway, here's what happens.
This pulse thingamajig can tell how much oxygen is floating around in your
blood, and it sends out a number. If you have plenty of oxygen, then the
number will probably be 98 or 99 or even 100! If you don't have enough
oxygen, the number will be lower, and you may need to use a mask to get
some more. Oxygen is something that you need to have to breathe easily.
Remember the mask that Kim showed you? |
