- Reduces cost and waste
- Will not stimulate latex sensitivity
The Pall BB50T Breathing Circuit Filter is a highly efficient, single use, bidirectional bacterial/viral removal filter. It is indicated for use on ventilators, water bath humidifiers and other medical gas equipment (e.g. oxygen concentrators, nebulizers) where the gas outlet fitting complies to ISO 5356-1 for the protection of the patient, staff, equipment and environment. It provides >99.999% bacterial and viral efficiency, and it has a maximum use life of 48 hours when not exposed to nebulized medication.
Note: Filter changes should be performed in accordance with department policy. Ventilator pressure alarms should be in use at all times. Although rare, progressive increase in resistance to airflow may occur during liquid drug nebulization. Therefore, vigilance should be maintained. Under certain conditions, the nebulization of drugs or solutions may result in a sudden increase in the resistance of the expiratory filter, necessitating replacement. For example, if drugs or solutions that contain detergents, have surfactant properties, or contain mucolytics are ultrasonically nebulized or nebulized in the presence of a heated humidifier, an increased risk of greater resistance to flow may be observed due to blockage of the hydrophobic membrane. Therefore, prior to nebulization of drugs or solutions for the first time, consult with the drug product manufacturer and closely monitor airway pressure to assure continuing air flow to the patient. If resistance is found in the filter, remove the filter from the breathing circuit and replace with a new filter.
The ceramic bonded, pleated hydrophobic membrane of the Pall BB50T minimizes potential contamination by both airborne and liquidborne microorganisms.1-4
It has been specifically validated to remove Hepatitis C virus1
, Mycobacterium tuberculosis2
, and Staphylococcus aureus.3
It has also been demonstrated to display a water intrusion pressure (hydrophobicity) in excess of 50 cm H2
The Pall BB50T filter is free of natural latex rubber, and it has been tested to retain natural rubber latex allergens contained in liquids and airborne particles.5-6
It protects healthcare staff and the environment from medication exposure by removing aerosolized ribavirin7,8
, and methacholine11
exhaust droplets. Finally, it minimizes equipment down time by shielding transducers from damage due to water and medication.
