負壓隔離病房的設計除保持病房壓力低於周遭環境的負壓外，尚須能藉通風有效排除其中的病原體。本研究使用追蹤氣體濃度衰減法量測病房內各區間的有效空氣交換率，並配合殘留時間測定判斷病房各區間內的有害物移除效果。其中殘留時間以 50% 脈衝釋放追蹤氣體被排除所需的時間，t50%，做為指標。
本研究在病房內以上述兩種判定標準於病房內不同區間進行測試，歸納得到二者的相關性，並藉此探討負壓隔離病房內所可能存在的通風死角與異常氣流，這些現象都會妨礙病房內病原體的移除。同時也發現室內空調氣流也會對病原體排除效果造成顯著影響。

A negatively-pressurized isolation ward must maintain a ward pressure lower the ambient pressure. which prevent the pathogen from escaping into the environment. The ventilation in the ward is also required to remove the pathogen effectively.
This study measured the effective air change rate at different locations in a negatively-pressurized ward by the concentration decay of trace gas concentration. The resident times were also measured with trace gas released at different locations in the ward. The time for 50% of trace gas being exhausted, t50%, was used as an index.
The results of air change rate and t50% was compared at nine locations in the ward. The ventilation dead space and anomaly airflow, both would prevent the pathogen to be effectively removed, were able to be identified by the experimental results. It was found that the airflow generated by an air-condition in the ward may also have a significant effect on the pathogen-removing.
