Ouch.
And an interesting asymmetry:
> The left main bronchus is the most common site of pin impaction.
> Although inhaled foreign bodies commonly lodge in the right bronchial tree, scarf pins more often settle in the left tree. Numerous authors have attributed this finding to the Bernoulli phenomenon, which states that coughing, laughing, or speaking creates stronger negative pressure in the narrow left bronchus than in the wide right bronchus.
- bookofjoe 2y agoThat is EXTREMELY interesting to this retired anesthesiologist who up to your comment/quotation believed ALL foreign bodies lodged in the right main stem bronchus due to its more vertical orientation. 40 years ago this month, in the journal Anesthesiology, my colleagues and I published a paper describing how a detached fiberoptic light bulb ended up in the right main stem bronchus.
