Severity

Severity of airway obstruction based on FEV1 %Predicted:

>70% Mild
≥60% and <70% Moderate
≥50% and <60% Moderately Severe
≥35% and <50% Severe
<35% Very Severe
1. Using the reported results how should this spirometry test be interpreted?
 
 
 
 
 
 
 
2. After reviewing the spirometry test results, flow-volume loop, volume-time curve and trends, do you think that the reported FVC is:
 
 
 
3. Is the reported FEV1:
 
 
 
4. Is the FEV1/FVC ratio:
 
 
 
5. After assessing all of the available information what are the implications?
