Vertical Laminar Flow Hood Aseptic Technique

The direction of air flow may be horizontal or vertical.

Vertical laminar flow hood aseptic technique.

Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation. Cytotoxic agents radioactive agents antimicrobial agents. Vertical laminar flow hoods. Manipulative technique is also different in a vertical flow hood.

T f using a laminar flow hood in an open room is no safer than preparing products on a countertop. Development maintenance of good aseptic technique in personnel who prepare administer sterile products 2. Horizontal flow hoods are most commonly used with the more costly vertical flow hoods being reserved for agents that may produce an environmental hazard e g. Turbulence patterns around objects in the vertical flow hood will be different from that in horizontal flow units.

Development maintenance of sterile compounding area complete with sterilized equipment supplies 3. Provide a constant flow of air out of the work area to prevent room air from entering. 99 99 particle free air is forced downward toward the work surface. Items not sterile including fingers and hands must be kept.

The air flowing out from the hood suspends and removes contaminants introduced into the work area by personnel. Vertical laminar flow hoods are often chosen because they resemble on a small scale the design of a laminar flow cleanroom in which fan filter units are typically positioned in the ceiling. Provide clean air to the working area. While laminar airflow hoods prevent airborne contamination they do not guarantee a sterile product.

Supplies may be arranged to the sides and the back of the area in which manipulations will be performed. Development maintenance of skills needed to properly use laminar airflow workbench lafw or laminar airflow hood. Use precautions to minimize contamination in the product preparation area.
