Laminar airflow and mixing ventilation: Which is better for operating room airflow distribution near an orthopedic surgical patient?

G Cao, AM Nilssen, Z Cheng, LI Stenstad… - American journal of …, 2019 - Elsevier
Background There has been little research on the performance of laminar airflow (LAF) and
mixing ventilation (MV) systems regarding clean airflow distribution near a surgical patient in
operating rooms (ORs). The objective of this study was to examine the performance of LAF
and MV systems in ORs at St Olavs Hospital in Norway. Methods Experimental
measurements were conducted in 2 ORs equipped with LAF and MV systems. Results
Under real operating conditions, airflow distribution from the LAF system was disrupted, and …
