Figure 1From: Detection of Pseudomonas aeruginosa in sputum headspace through volatile organic compound analysisVolatile analysis flow-chart. Sputum culture was first analyzed for the presence of P. aeruginosa. The PA model analyzed positive versus negative P. aeruginosa patients. In a second step the Leeds criteria were applied to each patient to determine P. aeruginosa chronic colonization [32]. The PACC model compared chronically colonized patients with non-chronically colonized patients. PA = P. aeruginosa; PACC = P. aeruginosa chronic colonization.Back to article page
