Breath Monitor (Magoun Sq)

That may not be the official name of the device. It is something they give you to blow into to I believe increase your lung capacity?

I recently had surgery and was sent home with this. I never used it. Even though there is a small tear in the bag. (Probably I caught it on something during trip home) It is in the original packing and as I said never used.
