Mainstem Bronchus Intubation: Sensitivity and Specificity

Introduction: A complication of intubation where the endotrachial tube is advanced too far down the trachea to end up in one of the bronchi (more commonly on the right because of its straight angle). This can be detected easily on chest x-ray.

The sensitivity and specificity of findings for Mainstem Bronchus Intubation are listed below. See the left navigation bar to change the display.

**Note that calculating probabilities from more than one finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)
