Bioaerosols in showers


Effectiveness of membrane integrated shower outlets for increasing patient safety (completed)

PI: Lars Angenent

Because of profound immunosuppression, blood and marrow transplant (BMT) patients are at risk of acquiring pathogenic microorganisms from seemingly benign sources, including the hospital water supply. Showers are particularly problematic because opportunistic pathogens present in the shower water are transferred from the liquid into breathable particulates in the air via a process called aerosolization. Therefore, we propose to test an immediately available solution that may decrease the risk of exposure to these pathogens during a period of extreme vulnerability for BMT patients.
