Summary of sleep-disordered breathing indices.
| AHI | ODI | Normal (AHI < 1.5 Events/h) | Mild (1.5 < AHI < 5 Events/h) | Moderate (5 < AHI < 10 Events/h) | Severe (AHI > 10 Events/h) | |
|---|---|---|---|---|---|---|
| Polysomnogram (n = 20) | 18.6 ± 35.8(0.7–118.3) [3.0; 11.1] | 13.5 ± 26.7(0.0–85.0) [2.3; 7.4] | 3 (15%) | 12 (60%) | 0 (0%) | 5 (25%) |
| Home ApneaLink (n = 20) | 6.2 ± 10.7(0.2–48.5) [2.6; 6.3] | 10.9 ± 11.4(1.0–49.1) [7.4; 1.0] | – | 7 (35%) | 4 (20%) | 3 (15%) |
| Lab ApneaLink (n = 19) | 11.6 ± 21.8(0.0–73.7) [2.4; 5.6] | 16.9 ± 24.0 (0.4–77.4) [8.5; 10.1] | 7 (35%) | 7 (35%) | 1 (5%) | 4 (20%) |
Results expressed as mean ± standard deviation (range) [median; interquartile range] or number (percentage). AHI = apnea-hypopnea index, ODI = oxygen desaturation index.
