Vertical Laminar Flow Hood Aseptic Technique

Development maintenance of good aseptic technique in personnel who prepare administer sterile products 2.

Vertical laminar flow hood aseptic technique.

Manipulative technique is also different in a vertical flow hood. Development maintenance of skills needed to properly use laminar airflow workbench lafw or laminar airflow hood. 99 99 particle free air is forced downward toward the work surface. 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.

While laminar airflow hoods prevent airborne contamination they do not guarantee a sterile product. Vertical laminar flow hoods. Development maintenance of sterile compounding area complete with sterilized equipment supplies 3. Turbulence patterns around objects in the vertical flow hood will be different from that in horizontal flow units.

Use precautions to minimize contamination in the product preparation area. The air flowing out from the hood suspends and removes contaminants introduced into the work area by personnel. Room air in red enters the system from above the hepa filter. The direction of air flow may be horizontal or vertical.

Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation. T f using a laminar flow hood in an open room is no safer than preparing products on a countertop. 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. What is the maximum number of particles in a clean room buffer room and ante room.

Supplies may be arranged to the sides and the back of the area in which manipulations will be performed. Use strict aseptic technique to avoid introduction of contaminants into the hood. Cytotoxic agents radioactive agents antimicrobial agents.
