Document Summary
Sternal angle (angle of louis/ manubriosternal angle) -- where the trachea divides into 2 main bronchi. Costal angle-- should be 90 degrees-- found just below the xiphoid process of the sternum- if it"s greaterthan 90degrees it"s too much. Intercostal spaces- found btwn the ribs: people with difficulty breathing - there will be indrawing of the intercostal space- increased work on breathing -- this is not well seen for people with high muscle mass or overweight. Posterior thoracic cage: looking for symmetrical shape -- symmetrical change. Twelfth rib- floating ribs -- at risk to break when people fall -- ie: resp assessment bc fractured rib could puncture lung. Reference lines: anterior and posterior: recall to assess ant, post and laterally ( hear the right middle lobe to listen to breathing sounds in the midaxillary line) ** recall doing this. Trachea & bronchi-- bifurcate at the angle of louis.
