Background:
The Chilean Metropolitan region is exposed to nitrogen dioxide levels that are above the WHO Air Quality Guidelines.
Aim:
To report the exposure to nitrogen dioxide levels and to estimate the damage that these levels can cause in health.
Material And Methods:
Description of nitrogen dioxide levels in the Chilean Metropolitan Region between 2016 and 2018 and the attributable risk of these levels on the population health.
Results:
The average hourly levels of nitrogen dioxide exceeded 40 pg/m3. In the three years studied, 11,686 attributable health problems were estimated, including deaths, hospitalizations, and attendance to emergency rooms.
Conclusions:
We provide valid information to review and adjust primary air quality standards for nitrogen dioxide. The exposed population should be educated about the risk of this exposure to promote self-care.

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...

Respiratory Assessment: Purpose and Indications
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
