Bedside Air Quality in ICU and Clinical Outcome

There is a close relationship between air pollution and cardiovascular disease. Small particulate matter and inhalable particulate matter in the air are the main components of air pollution, which can enter the respiratory system and enter the bloodstream through alveoli. These particles are believed to have the ability to trigger inflammatory responses, which are one of the important factors leading to cardiovascular disease. Some studies suggest that air pollution may increase the risk of cardiac events, such as arrhythmia and myocardial infarction, by affecting the autonomic function of the heart. Air pollution in the ICU may have a series of adverse effects on critically ill patients, especially those with underlying heart disease or elderly patients, but there is no relevant research to confirm this.
