“…Por isso, é recomendado o uso de tubos traqueais, visto que permitem a aspiração intermitente da secreção acumulada acima do balonete (cuff), com pressões altas, ou contínuas. Essa medida visa mitigar a ocorrência PAVMI por microaspirações de secreção contaminada que tende a acumular na região medial da traqueia, acima do balonete (Barbas & Couto, 2012;Souza & Santana, 2012).…”

“…1.2 VAP occurs in approximately 10 to 25% of patients who require invasive mechanical ventilatory support for more than 24 hours. 3 It is the hospital infection that most commonly affects patients admitted to the Intensive Care Unit (ICU), representing up to 60% of hospital infections, 4,5 depending on patients' comorbidities, clinical status and duration of mechanical ventilation (MV). 6 According to the Brazilian National Regulatory Health Agency (ANVISA -Agência Nacional de Vigilância Sanitária), VAP is characterized by a pulmonary infection occurring after 48 hours of endotracheal MV, associated with one or more chest radiographs with the presence of a new, persistent or progressive infiltrate, fever (> 38°C) or leukocytosis or leukopenia, worsening pulmonary secretions or worsening pulmonary function.…”

“…One of the causes for the development of VAP is the presence of microaspirations of secretion above the cuff [ 5 , 6 , 11 13 ], i.e., a favorable site for colonization and infection of microorganisms, including bacteria, which can reach the lower airways [ 2 , 5 , 12 14 ].…”

“…Additionally, the cost of treating patients with VAP is higher than that of patients without the disease, which contributes to significantly increase hospital costs [9]. One of the causes for the development of VAP is the presence of microaspirations of secretion above the cuff [5,6,[11][12][13], i.e., a favorable site for colonization and infection of microorganisms, including bacteria, which can reach the lower airways [2,5,[12][13][14].…”
