Patient characteristics
| Patient no | Age (years) | FEV1 (% pred) | FVC (% pred) | RV (% pred) | FER (%) | Tlco (% pred) | TLC (% pred) | Paco2 (kPa) | Pao2 (kPa) | pH | BMI (kg/m2) |
|---|---|---|---|---|---|---|---|---|---|---|---|
| FEV1 = forced expiratory volume in 1 second; RV = residual volume; FER = forced expiratory ratio (FEV1/VC); Tlco = carbon monoxide transfer factor; Paco2, Pao2 = arterial carbon dioxide and oxygen tensions; BMI = body mass index. | |||||||||||
