He filled his lungs with air and looked her in the eye.

She filled her lungs slowly and let the air out.

He tried to take a breath and found his lungs filled with water.

Cold air filled his lungs, but did little to cool him.

All at once there was enough air to fill her lungs.

"I was just trying to fill my lungs with air."

Smoke filled everyone's lungs and made running even more difficult.

He fills my lungs with those words and I go under.

He kept trying to breathe as his lungs filled with blood.

Now there would be no struggle as her lungs filled with the river.
