Time frames:
0:00–0:05 seconds: Compression of common femoral vein in short axis (transverse) plane.
0:06–0:14 seconds: Normal respiratory phasicity in long-axis (longitudinal) view.
0:15–0:18 seconds: Valsalva maneuver resulting in the cessation of venous flow.
0:19–0:27 seconds: Release phase of the Valsalva maneuver resulting in flow augmentation, followed by the return of normal respiratory phases (compare frame 0:06).
0:27–0:30 seconds: Augmentation of venous flow resulting from compression of the calf and the thigh (respectively).
0:31 seconds: End of the video femoral vein compression in short-axis (transverse) view.
