Lung Compliance is a measure of how easily the lungs and chest wall can stretch or expand. Total Compliance refers to the overall distensibility of the entire respiratory system (lungs and chest wall). Specific Compliance is total compliance divided by the lung volume (e.g., Functional Residual Capacity). It's useful because it normalizes compliance for lung size, allowing for comparison between individuals or different conditions. In emphysema: The elastic fibers in the lung tissue are destroyed, making the lungs much more* distensible or "floppy." This leads to a significant increase* in both total compliance and specific compliance. The lungs become very easy to inflate but lose their natural elastic recoil, making it difficult to exhale air effectively. This results in air trapping and hyperinflation. What's next?
