Table 4. Impulse oscillometry parameters for high-density exposure and low-density exposure during sleep.
| High-density exposure (n = 3) | Low-density exposure (n = 12) | p-value | ||
|---|---|---|---|---|
| Height (cm) | 119.0 | 125.0 | 0.233 | |
| Weight (kg) | 22.0 | 25.5 | 0.295 | |
| BMI (kg/m2) | 16.0 | 16.0 | 0.945 | |
| IOS | R5, kPa/L/s | 1.1533 | 0.9092 | 0.106 |
| R20, kPa/L/s | 0.8067 | 0.6783 | 0.192 | |
| R5-R20, kPa/L/s | 0.3467 | 0.2308 | 0.078 | |

High-density exposure = airborne level during sleep ≥ 32.4 μg/m3; low-density exposure = airborne level during sleep < 32.4 μg/m3. R5, resistance at 5 Hz; R20, resistance at 20 Hz; R5-R20, change in resistance between 5 and 20 Hz; X5, reactance at 5 Hz; AX, reactance area.
a p < 0.05 depicts a statistically significant difference.
