The parameters assessed by inspection or auscultation of the upper and lower chest and nares on a scale of 0, 1 or 2 using this system are :
Synchronized vs. minimal lag or sinking of the upper chest as the abdomen rises. In the most extreme instances, a seesaw-like movement of the chest and abdomen is observed and would be given a score of 2.
Retraction between the ribs is rated as none, minimal or marked.
Similarly retraction below the xiphoid process are rated as none, minimal or marked.
There should be no nasal flaring. Minimal flaring is scored 1 and marked flaring is scored 2.
Grunting that is audible with a stethoscope is scored 1, and grunting that is audible without using a stethoscope is scored 2.
As you can see on the slide, the higher the score, the more severe the respiratory distress.
