Abstract

The purpose of this study was to examine how many particles and airborne microorganisms are dispersed through nurses' care and to describe the distribution of particles in laminar airflow. Although the amenity in biological clean room (BCR) is of great importance for reverse-isolated patients, taking care of a patient in BCR with direct contact or face-to-face is strictly limited in many facilities in Japan. Nurses have conceived from their experiences that they could benefit more from active intervention rather than strict isolation of an immunocompromised patient, and some literatures have supported this. However, little was known about the actual risk of air contamination caused by nurses. We built a mockup patient room with HEPA filter unit and conducted an experimental study using bed making, which appears to generate the most number of particles compared to other nursing care behaviors. While changing unwoven or cotton sheets, we got samples of M Air T<SUP>TM</SUP> to find colonies of bacteria and the number of particles by laser particle counter. There were some difference in particle diameter spectrum between unwoven sheets and cotton bed sheets.
