Respiratory lung function - lung function unit
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.
