These changes in climate and air quality substantially increase respiratory morbidity and mortality for patients with common chronic lung diseases such as asthma and COPD and other serious lung diseases.
10 lis 2023 · Oxidative stress can further amplify the impact of air pollution on respiratory health by deteriorating lung function and hindering the lungs' ability to remove pollutants (Miller, 2020). Additionally, exposure to air pollution can alter the immune system, leading to shifts in immune cell types and their responses to pathogens and allergens ...
Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion. Ventilation is the process by which air moves in and out of the lungs.
1 maj 2013 · Many effects of climate change (more heat, more extreme weather events, and higher ozone levels, among others) are more ominous for the roughly 12 million people who have COPD and other serious lung diseases in the United States.
11 sty 2021 · Breathing ozone irritates the lungs and the rest of the respiratory system, leading to shortness of breath. It can also cause inflammation and make the lungs more susceptible to other triggers of inflammation, such as pollen and mold spores, sometimes leading to infections.
The climate change exposures with the strongest evidence base for promoting adverse respiratory health outcomes are extreme heat (often with cooccurring tropospheric ozone) and the particulate matter (PM) component of wildfire smoke, particularly that with a diameter of 2.5 μm or less (PM 2.5).
At high elevations, global warming is predicted to increase barometric pressure (Moore and Semple, 2009), an effect which offsets the impact of O 2 loss on the O 2 partial pressure and which dominates above 3,000 m.
