Sepsis can lead to the failure of multiple organs in the human body and is fatal. A new type of treatment for sepsis is to use micron-sized magnetic beads to filter 80% of pathogens from the blood of patients with sepsis to make antibacterial drugs more effective Play a role. What are the necessary conditions for this new therapy to work? ['No germs will hide in areas with low blood supply to avoid blood filtration.', "Many symptoms of sepsis are caused by the body's own inflammatory response, not by the pathogen.", 'Reducing the number of pathogens can help improve drug efficacy.', 'The size of the magnetic beads is 1/8 of the diameter of the red blood cells, which can ensure the smooth flow of the salt solution containing magnetic beads.']
