Predictors of sleep disordered breathing (SDB) and diurnal respiratory failure
| Predictors | Sensitivity (%) | Specificity (%) | AUC (%) |
|---|---|---|---|
| IVC=inspiratory vital capacity; Pimax=maximal inspiratory pressure; HV=hypercapnic hypoventilation; dRF=diurnal respiratory failure; AUC=area under the curve. | |||
| IVC (%) | |||
| <60: SDB onset | 91 | 89 | 97 |
| <40: continuous HV | 94 | 79 | 98 |
| <25: dRF | 92 | 93 | 96 |
| Pimax (kPa) | |||
| <4.5: SDB onset | 82 | 89 | 85 |
| <4.0: continuous HV | 95 | 65 | 80 |
