- Abstract
- To prevent secondary infections in national inpatient isolation units, this study conducted flow analysis for opening/closing speeds of sliding doors of negative pressure isolation rooms and medical workers’ moving speeds among various factors that might cause outflow of contaminated air from negative pressure isolation rooms to the outside. Subject situations were divided into cases where medical workers’ moving speed remained the same while opening/closing speed of doors changed and cases where opening/closing speed of doors changed while medical workers’ moving speed remained the same to figure out internal flow characteristics of negative pressure isolation rooms and anteroom. Three speeds were designated for each of sliding door opening/closing speeds and medical workers’ moving speeds. Results showed that the outflow of contaminated air decreased as sliding door opening/closing speeds increased and as medical workers’ moving speeds decreased. Results of this study can be used as evidentiary material to set standard operation procedures to minimize diffusion of contaminated air where national inpatient isolation units are designed and operated.
