Heart (E) Wave

This waveform applies a pressure pattern that mimics

the shape as seen on an electrocardiogram

Heart (P) Wave

This waveform applies a pressure pattern that mimics

the actual pressure wave generated by a heartbeat.

Static Wave

This waveform applies a constant state of pressure.
