In vitro and in vivo studies have shown that various strains of "viridans streptococci" (nongroupable alpha-hemolytic streptococci) inhabiting the oropharynx suppress the growth of gram-positive and gram-negative microorganisms. The proportion of Firmicutes and Proteobacteria is increased in patients with upper airway cough syndrome (UACS), which replaces the dominance of Streptococcus and Neisseria in the pharynx of a normal population. Ventilation involves placing an endotracheal tube down the windpipe to deliver oxygen directly to the lungs, which is a life-saving procedure but not one without risks.
