From: Expiratory flow rate, breath hold and anatomic dead space influence electronic nose ability to detect lung cancer

Figure 1

The effect of expiratory flow, breath hold and dead space on principal components. The collection-related factors caused significant differences only in healthy subjects (p < 0.05), the effect was not significant in patients with lung cancer (p > 0.05). Comparing to baseline measurements both higher expiratory flow and breath hold caused significant changes in PC1, PC2, PC3, while the inclusion of anatomic dead space affected only PC1. Data are expressed as mean ± SD. *-p < 0.05, **-p < 0.01, ***-p < 0.001, NS-not significant.
