What is the anatomical reason for the left bronchus to be more elevated than the right bronchus? Why in most cases of aspiration of foreign material by children is the object found in the right bronchus?
by

1 Answer

Answer :

The left bronchus is more elevated than the right bronchus because of the position of the heart in the left side of the chest, anterior and inferior to the left bronchus. Accidentally aspired objects are frequently found in the right bronchus because the inferior angle between the trachea and this bronchus is lower than the inferior angle between the trachea and the left bronchus since the left bronchus is more horizontalized. Therefore aspired objects tend to fall in the right side (bronchus) and not in the left.

When measuring the blood pressure in each of the patient’s arms, the nurse recognizes that in the normal adult, the pressures a) differ no more than 5 mm Hg between arm pressures. Normally, in the absence of disease of the vasculature, there is a difference of no more than 5 mm Hg between arm pressures. b) must be equal in both arms. The pressures in each arm do not have to be equal in order to be considered normal. c) may vary 10 mm Hg or more between arms. Pressures that vary more than 10 mm Hg between arms indicate an abnormal finding. d) may vary, with the higher pressure found in the left arm. The left arm pressure is not anticipated to be higher than the right as a normal anatomical variant.
