Assessment of spontaneous breathing pattern by whole body plethysmography

Whole Body Plethysmography - Measuring Principle

  • During normal breathing, the box pressure signal due to tidal volume expansion is about 10 times larger than that resulting from alveolar gas decompression.
  • Thus, there is only minimal information available regarding the resistance of the conducting airways, but
  • tidal volume, respiratory rate, and timing can be reasonably estimated.
