Perfluorochemicals (PFCs) can transport oxygen and aid gas exchange. Perfluorocarbon liquid ventilation (PLV) shows promise for treating acute respiratory failure in humans, with ongoing studies evaluating its efficacy.

Area of Science:

  • Biomedical Engineering
  • Pulmonary Medicine
  • Medical Chemistry

Background:

  • Perfluorochemicals (PFCs) possess oxygen transport capabilities, demonstrated by Clark and Gollan in 1966.
  • PFCs have dual medical applications: as artificial blood substitutes and for liquid ventilation.
  • Perflubron, a specific PFC, also serves as a contrast agent in radiology.

Purpose of the Study:

  • To review the established and emerging applications of perfluorochemicals in medicine.
  • To detail the methodologies of total liquid ventilation (TLV) and partial liquid ventilation (PLV).
  • To summarize the evidence supporting PFC liquid ventilation in acute respiratory failure and its clinical translation.

Main Methods:

  • Intravenous PFCs require emulsification in phospholipids.

  • Intrapulmonary application uses sterile pure PFC solutions.
  • Liquid ventilation techniques include Total Liquid Ventilation (TLV) and Partial Liquid Ventilation (PLV).

    • Main Results:

    • Animal studies confirm PFC liquid ventilation enhances gas exchange and pulmonary function in acute respiratory failure.
    • First human application of liquid ventilation reported in a neonate in 1989.
    • Ongoing FDA-approved studies since 1995 investigate PLV efficacy in severe respiratory failure across all age groups.

    Conclusions:

    • PFC liquid ventilation has demonstrated efficacy in animal models of acute respiratory failure.
    • Human experiences with liquid ventilation are expanding across neonatal, pediatric, and adult populations.
    • Partial liquid ventilation (PLV) may become a valuable therapeutic option for severe acute lung injury if ongoing human trials confirm its effectiveness.
