Lung function at term in different cohorts
| Cohort | Functional residual capacity | Compliance | Specific conductance | Gas-mixing efficiency | |
|---|---|---|---|---|---|
| Units | n | mL/kg | mL/cm H2O, kg | 1/cm H2O, s | Moment ratio |
| Full-term controls | 50 | 22.0 (0.4) | 1.52 (0.05) | 0.20 (0.01) | 2.28 (0.04) |
| All preterms* | 37 | 15.1 (0.6) p<0.001 | 0.73 (0.04) p<0.001 | 0.27 (0.03) p=0.01 | 2.68 (0.05) p<0.001 |
| Preterms without BPD* | 13 | 17.2 (1.1) p<0.001 | 0.83 (0.07) p<0.001 | 0.20 (0.02) p=0.81 | 2.56 (0.07) p=0.001 |
| Preterms with BPD† | 24 | 14.0 (0.7) p=0.02 | 0.68 (0.04) p=0.06 | 0.32 (0.04) p=0.005 | 2.75(0.06) p=0.07 |
