Study of Exhaled Nitric Oxide in Subjects with Suspected Obstructive Sleep Apnea: A Pilot Study in Vietnam

Figure 2

(a) Correlation between post-PSG CANO and AHI in subjects with OSA. There was a significant correlation between CANO and AHI (, ). CANO: alveolar concentration of nitric oxide; AHI: apnea-hypopnea index. (b) Correlation between post-PSG CANO and AHI in control subjects. There was no significant correlation between CANO and AHI (, ). CANO: alveolar concentration of nitric oxide; AHI: apnea-hypopnea index. (c) Correlation between post-PSG CANO and nadir SpO₂ in subjects with OSA. There was a significant correlation between CANO and nadir SpO₂ (, ). CANO: alveolar concentration of nitric oxide.
