Pulse Oximetry for the Detection of Obstructive Sleep Apnea Syndrome: Can the Memory Capacity of Oxygen Saturation Influence Their Diagnostic Accuracy?

Table 6

Adjusted desaturation index with different data storage rates.

	1 Hz	0.5 Hz	0.25 Hz
ADI2	33.9 (2)	33.4 (1.95)	33.5 (2.1)
ADI3	24.9 (2)*	24 (1.96)*	23.8 (2)**
ADI4	18.2 (1.8)*	17.4 (1.74)*	17.3 (1.74)**

Values are expressed as mean (std. error). ADI2, 3, and 4: adjusted desaturations index ≥2%, 3%, and 4%.
*Pairwise comparisons between ADI3/4 1 s and ADI3/4 2 s: 𝑃 0.01.
**Pairwise comparisons between ADI3/4 1 s and ADI3/4 4 s: 𝑃 0.001.
