Impact of chronic obstructive pulmonary disease severity on diaphragm muscle thickness

Conclusion The static TD measured at RV and at TLC are preserved in COPD. The TF bilaterally was significantly decreased in COPD group and is decreased with increasing severity of COPD. The negative correlation of TF and PaCO2 indicates that the diaphragm dysfunction is the main contributor to neuromuscular respiratory failure in COPD patients.
