[Problems in visiometry examining tracheo-bronchial-secretions (author's transl)]

Area of Science:

• Respiratory Physiology
• Biomedical Engineering
• Medical Diagnostics

Background:

• Tracheo-bronchial secretions play a crucial role in respiratory health.
• Accurate measurement of secretion viscosity is important for understanding mucociliary clearance.
• Previous methods for assessing secretion properties have limitations.

Purpose of the Study:

• To document the influence of secretolytic therapy on tracheo-bronchial secretions.
• To evaluate the reliability of a modified cone and plate viscosimeter for this purpose.
• To compare this method with other viscosimetry techniques.

Main Methods:

• Examination of tracheo-bronchial secretions from 60 tracheotomied patients.
• Utilized a modified cone and plate viscosimeter for viscosity measurements.
• Comparative analysis with established viscosimetry techniques.

Main Results:

• The modified cone and plate viscosimeter demonstrated applicability in assessing tracheo-bronchial secretion viscosity.
• Reliability of the method was discussed in the context of clinical application.
• Comparative data highlighted the strengths and weaknesses of the technique.

Conclusions:

• The modified cone and plate viscosimeter is a viable tool for characterizing tracheo-bronchial secretions.
• This method aids in the documentation of changes in secretions, potentially due to secretolytic treatments.
• Further validation and comparison with other techniques are essential for widespread adoption.
