Question

Proofread for Capitalization and Punctuation errors.

Carina was inspected at that time, which appeared sharp with no mucosal lesions noted. A 2% lidocaine was instilled over the carina. Right main stem bronchus was inspected next. Opening to the right upper lobe was inspected, however 2 areas of abnormality were detected. All 3 anterior, posterior, and apical, segments were visualized without any obstruction noted.

Thanks!

Unneeded comma in here -- All 3 anterior, posterior, and apical, segments were visualized without any obstruction noted.
