Vertical Laminar Flow Hood Aseptic Technique

Room air in red enters the system from above the hepa filter.

Vertical laminar flow hood aseptic technique.

Turbulence patterns around objects in the vertical flow hood will be different from that in horizontal flow units. Vertical laminar flow hoods. Development maintenance of sterile compounding area complete with sterilized equipment supplies 3. Cytotoxic agents radioactive agents antimicrobial agents.

Provide a constant flow of air out of the work area to prevent room air from entering. What is the maximum number of particles in a clean room buffer room and ante room. 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. Provide clean air to the working area.

Use precautions to minimize contamination in the product preparation area. While laminar airflow hoods prevent airborne contamination they do not guarantee a sterile product. 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.

Items not sterile including fingers and hands must be kept. The direction of air flow may be horizontal or vertical. Development maintenance of skills needed to properly use laminar airflow workbench lafw or laminar airflow hood. 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.

Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation. 99 99 particle free air is forced downward toward the work surface. Supplies may be arranged to the sides and the back of the area in which manipulations will be performed.
