The answer is a qualified "yes." Bacteria and viruses are trapped in Blueair filters. No air filtration system is 100% effective at removing 100% of all bacteria and viruses. However, Blueair's combination of mechanical and active electrostatic filtration provides exceptionally high levels of protection.

Most patients with weakly or non-safe ferromagnetic implants will be given a card, which they keep on their person at all time, that can help isolate if it is safe to do an MRI.

IVC Filters and Their Risks While IVC filters have the potential to be life-saving, preventing strokes and heart attacks in patients vulnerable to the formation of blood clots and deep vein thrombosis, studies have found that they can also fail and cause life-threatening complications.

IVs contain a lot of salt, which could have a negative effect on people with heart disease or high blood pressure, Goldfarb said. Improperly inserted IVs can create a stroke-causing air embolism or cause the fluids to leak into nearby tissue, Glatter said. They may also expose a person to possible infection.

IVUS uses high-frequency sound waves (also called ultrasound) that can provide a moving picture of your heart. ... The transducer is attached to the end of a catheter, which is threaded through an artery and into your heart. The sound waves bounce off of the walls of the artery and return to the transducer as echoes.

IVIG generally takes about 3 hours for the infusion to be completed. This estimate only includes the time that it takes for the medication to go into your body; it will take additional time to prepare supplies and medications and to place the IV catheter. If your body reacts to the infusion, it will take longer.

In an IVP exam, an iodine-containing contrast material is injected through a vein in the arm. The contrast material then collects in the kidneys, ureters and bladder, sharply defining their appearance in bright white on the x-ray images. X-ray images are typically stored as digital images in an electronic archive.

True HEPA. True HEPA filters are effective at removing ultra fine particles (think: dust, dander, pollen, mold and other common allergens in the home). The industry standard for such is that the unit must be able to remove at least 99.97% of particulates measuring 0.3 micron diameter in a lab setting.

Continuous veno-venous haemodialysis (CVVHD) uses the principle of diffusion to remove solutes from the patient. Where blood flows in one direction through the filter, a dialysate fluid flows on the other side of the filter membrane in the opposite direction of the blood.

IVC Filter Migration This can happen for several reasons, including the vein being too large to accommodate the filter. Migration of a filter to heart or lungs is a medical emergency that requires immediate intervention.
