Table 3 Mean changes of impulse oscillometry (IOS), fractional exhaled nitric oxide (FENO) and exhaled carbon monoxide (eCO) measurements before and immediately after 30 min of cigar smoking (experimental session) or control session separately in young smokers with mild asthma (MA) and healthy smokers (HS)

From: Immediate effects of cigar smoking on respiratory mechanics and exhaled biomarkers; differences between young smokers with mild asthma and otherwise healthy young smokers
