Why can standing up fast or bending over cause a sudden COPD panic attack in which I can't catch my breath?

In brief: Increased pressure
Bending causes increased pressure in the abdomen which is in turn transmitted to the lungs causing shortness of breath.
Lungs with diminished reserves like in COPD are unable to adjust to that pressure increase. The standing up part is a different story.

In brief: COPD & Panic
With copd, standing up fast further lowers oxygen supply to brain as the blood pressure drops, hence warning signal from brain by sending down more adrenaline which can trigger panic.
