Additional Product Information

  • Bioinert

    The molecules of Liquivent,  a Perfluorocarbon (PFCs) called Perflubron (PFOB), are too large to be metabolized3. PFOB is bioinert, immiscible with other liquids, minimally absorbed4, and has no deleterious histological cellular or biochemical effects1.

  • Effective

    Due to Perflubron’s high density and low viscosity, most liquids and solids float on top of it. This allows toxic, damaging exudates as well as infectious material to float to the top, where they can be removed using suction5.

  • Respiratory Advantages

    Does not block oxygen transfer during lavage6 or elicit a cough reflex. Improves lung function, reduces inflammation7, and enhances surfactant phospholipid production2.

  • Available in Vials

    Liquivent is available in a 10ml or 50ml vial. Vials are Type 1 borosilicate assembled with butyl stoppers and crimped aluminum caps. Choose the option that works best for your hospital.

FAQ

What is the intended use?

Liquivent is for research use only in the USA. The CE-approved intended use is as an aid in removing debris, secretions, and foreign matter from the lungs via bronchoalveolar lavage (BAL).

How quickly does it evaporate?

While it does evaporate, there will be residual Perflurobron left in the lungs that should be suctioned out. When used for bronchial lavage, it is instilled into the lungs and suctioned back out.

What is a normal dosage?

10-20ml/kg for bronchial lavage.

How do I access Liquivent for research purposes?

Please contact customer service at 512-474-7878, submit a quote request form, or email info@origen.com for pricing and availability.
