초록

Purpose: In this study, we examine whether the pressure difference relation equation in foreign guidelines can be applied to negative pressure isolation ward(NPIW) in Korea. Supply/exhaust airflow rate and pressure difference in the negative pressure isolation were investigated to review the applicability, and the leakage area of entrance door was calculated and compared through the results. Methods:Supply/exhaust airflow rate and pressure difference were investigated in 24 hospitals (116 wards) through the testing, adjusting and balancing (TAB) and the facility verification report. Based on the results of the investigation, the air change per hour (ACH), supply/exhaust airflow rate difference, and pressure difference were confirmed. The leakage area was calculated and compared using the pressure difference relation equation provided by foreign guidelines. Results: The ACH in the ward and anteroom and the pressure difference met the required criteria. Even if the difference in supply/exhaust airflow rate difference was low, pressure difference of -2.5 Pa or more was identified. The leakage area calculated by the relation equation by two foreign guidelines was different. Implications: It is judged that the results of this study can be referred to when revising and developing guidelines for the safety of NPIW.
