The study's aim is to develop a bedside assay to detect pulmonary micro-aspirations of gastric contents. Such a test is needed to differentiate between frequent and infrequent aspirators so that interventions can be planned accordingly. A total of 2,200 aliquots of human tracheobronchial secretions are available for the project and will be used to determine measures of sensitivity, specificity, and reproducibility when comparisons are made between the bedside assay and the reference laboratory assay
