The POWERbreathe K-Series uses Electronic Variable Threshold Resistance Training to overcome this. This type of training offers a tapered loading resistance to match the contraction curve of your own breathing muscles throughout your entire breath.
Is it restricting the flow of air so you have to breathe harder?

It's an "inspiratory muscle trainer". That is, it increases resistance breathing in.
I can do the same with my lips (or a finger) and make funny noises too :)
