Satellite C-band usually transmits around 6 GHz and receives around 4 GHz. It uses large (2.4- 3.7 meter) antennas. These are the large white domes that you see on top of the cruise ships and commercial vessels.
Inferior Vena Cava Filter Placement and Removal. 1  During Inferior Vena Cava (IVC) filter placement, a filtering device is placed within the IVC, a large vein in the abdomen that returns blood from the lower body to the heart. Blood clots in the veins of the legs and pelvis can occasionally travel to the lungs where they may cause a pulmonary embolism or blockage.
Negative aspects of in-line IV filters include reduction of infusion flow rates secondary to filter clogging and added costs. In-line IV filters house a membrane that separates the whole unit into a patient side and an air-vent side. Proper priming techniques allow the fluid to fill the air-vent side first while saturating the membrane and then filling the patient side.
