When the physical act of breathing is strained, it cause an oxygen deficit. (Generally because you're not moving AIR in and out effectively ample to properly oxygenate the blood.)

Providing oxygen (mask or nasal canula) increases the concentration of oxygen in the air you inhale... so although you're not moving as much air within and out as you should, the high concentration of oxygen you're getting through the mask makes up for the difference.
