Rib cage distortability varies significantly among individuals. This mechanical property is closely related to the abdominal rib cage compliance, influencing respiratory mechanics.

Area of Science:

  • Respiratory Mechanics
  • Pulmonary Physiology
  • Biomechanics of the Thorax

Background:

  • The rib cage is divided into lung-apposed (pulmonary) and diaphragm-apposed (abdominal) compartments.
  • Understanding the mechanical properties of these compartments is crucial for respiratory function assessment.

Purpose of the Study:

  • To quantify rib cage distortion and distensibility in normal men.
  • To investigate the relationship between rib cage distortion and abdominal rib cage compliance.

Main Methods:

  • Magnetometry was used to measure cross-sectional areas of the pulmonary (RCp) and abdominal (RCab) rib cage compartments.
  • Diaphragmatic twitches were employed to induce distortion, and transdiaphragmatic pressure was measured.
  • Distensibility was calculated as percent distortion per unit of transdiaphragmatic pressure.

Main Results:

  • Significant individual variation in rib cage distensibility was observed (0.02 to 0.23%/cmH2O).
  • A strong positive correlation (r=0.92) was found between rib cage distortion and abdominal rib cage compliance.
  • A negative correlation (r=-0.90) existed between the restoring pressure (Plink) per percent distortion and abdominal rib cage compliance.

Conclusions:

  • Rib cage distortability exhibits wide inter-individual variability in healthy subjects.
  • Abdominal rib cage compliance is a key determinant of rib cage distortability during respiratory maneuvers.
