FEV1 to FVC Ratio and the Lung Age Formula of Hansen et al
Purpose: | To determine the ratio of FEV1 to FVC and to assess a patient's apparent lung age using the equation of Hansen et al. |
Specialty: | Pulmonology |
Objective: | clinical diagnosis, including family history for genetics, other testing, severity, prognosis, stage, complications |
ICD-10: | J20-J22, J40-J47, R94.2 |
