Objectives:
to determine the prevalence of bronchopulmonary aspiration in the Brazilian scenario, the factors associated with the incident and the variables associated with death.
Methods:
a cross-sectional and analytical study, carried out from analysis of notifications of incidents related to bronchopulmonary aspiration of the Health Surveillance Notification System, from January 2014 to December 2018.
Results:
of the 264,590 notifications, 553 referred to aspiration, whose prevalence rate was 0.21%. There was an association between the event and age, ethnicity, main medical diagnosis, country region, service type, health unit and consequences for patients. Furthermore, four independent predictor variables for death were found: living in the North or South regions, being elderly and receiving healthcare at night.
Conclusions:
the prevalence rate of bronchopulmonary aspiration was small, but with a negative impact on patients.

Factors Affecting Pulmonary Ventilation
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
