Evaluation of plethysmography for diagnosis of postintubation tracheal stenosis

Our study showed a weak correlation between X5% and tracheal narrowing making it unclear whether IOS can be used for physiological assessment of patients with tracheal stenosis. Stenosis length correlated with PEF making it a potential predictor of successful surgical approach. The correlation between IOS and spirometric values makes IOS a potential alternative in patients with suspected tracheal stenosis who are not able to perform spirometry. Larger scale studies should clarify the role of IOS in this pathology.

Evaluation of plethysmography for diagnosis of postintubation tracheal stenosis

Abstract: Significant relationships were found between plethysmography variables and rigid bronchoscopy findings in patients with post-intubation tracheal stenosis, and some formulas were developed to give an alternative estimate of stricture severity, without bronchoscopy.
