Laminar Air Flow
The most important part of the operating room, the central sterile area, is the area where the operating table and scrubbing table are located, and the tissue being operated on is unprotected, and the entry of even one microorganism can cause infectioJn. Because of this, it is very important to control the air in this area, which was almost impossible in the point box filter method.
For this reason, the use of laminar Airflow system is recommended in the standard book of Safe Hospital. The presence of laminar Airflow can prevent air turbulence and fresh and particle-free air can fall on the operating table slowly and at a suitable speed (0.23 to 0.25 m / s) mentioned in the standard book of Safe Hospital.
