In brief: Compresses heart

The fluid around the heart compresses the heart so that it cannot fill properly.
Therefore, the output of blood decreases so that less blood is pumped to the lungs and less to the resto fo the body. Thre is just not enough space ofr the heart to function normally and that will make you short of breath. Also, whatever caused the effusion may also affect the lungs, such as lung cancer.

In brief: Decreased blood flow

Tamponade is by definition a constriction of the heart.
The heart can not pump normally. Since bloodflow is decreased, so is the amount amount of oxygen delievered. Additonally, blood pressure in the lungs accumulates, since it is upstream from the problem, causing the lungs to engorge with fluid, leading to increased lung stiffness, and difficulty beathing.
