Table 1. Scoring criteria for lung function by auscultation.

Score	Expiratory efforts	Wheezing (High-pitched whistling sound made while breathing)
0	No expiratory effort	No wheeze
1	Earliest detection of increased expiratory effort	Earliest detectable wheeze by auscultation
2	Moderate expiratory effort (>1sec) observed with some abdominal effort	Audible wheeze in all lung fields by auscultation
3	Expiratory effort (>3 sec) with hard abdominal effort	Wheeze audible without stethoscope
