This study presents a method for preparing fully-inflated whole lung specimens for research and instruction. The technique involves extensive rinsing and air inflation to create permanent, light-colored lung specimens.

Area of Science:

  • Anatomical pathology
  • Medical education

Background:

  • Preserving anatomical specimens is crucial for medical education and research.
  • Existing methods may not consistently yield well-inflated and durable specimens.

Purpose of the Study:

  • To describe a novel method for preparing fully-inflated whole lung specimens.
  • To ensure specimens are suitable for long-term instruction and research.

Main Methods:

  • Lungs are removed, cannulated, and lavaged with tap water over 250 times to remove blood.
  • Specimens are inflated with dehumidified air to 30 cm H2O and dried under pressure.
  • Optional alcohol filling can be performed.

Main Results:

  • The method produces light-colored, fully-inflated whole lung specimens.

  • The resulting specimens are durable and suitable for permanent storage.
  • The technique ensures structural integrity for educational and research applications.

    • Conclusions:

    • This method provides a reliable way to prepare high-quality lung specimens.
    • The preserved lungs are valuable resources for anatomical study and scientific investigation.
