Introduction

When individuals breathe polluted air, the pollutants enter the respiratory system. Larger particles like PM10 are usually trapped in the upper respiratory tract, while finer particles such as PM2.5 penetrate deeper into the lungs, reaching the alveoli. These particles can cause irritation, inflammation, and damage to the respiratory system. The inhalation of particulate matter and gaseous pollutants triggers inflammatory responses in the lungs, involving the release of cytokines and chemokines. Prolonged inflammation can lead to chronic respiratory conditions. Air pollution has been associated with decreased lung function, especially in vulnerable populations such as children and the elderly. Reduced lung function can predispose individuals to respiratory diseases and hinder their ability to cope with respiratory infections.

Literature Review

Children living in urban environments with high levels of air pollution are more likely to develop asthma. Studies have shown that exposure to pollutants like nitrogen dioxide and particulate matter is associated with increased asthma exacerbations and reduced asthma control. Long-term exposure to air pollution has been linked to the development and progression of COPD. The inhalation of fine particles can aggravate symptoms in individuals with pre-existing COPD and increase hospitalizations. Air pollution weakens the respiratory system's natural defenses, making individuals more susceptible to respiratory infections. Particulate matter and other pollutants can act as carriers for infectious agents, leading to increased transmission rates. Elevated levels of air pollution, especially PM2.5, have been associated with an increased risk of lung cancer. The carcinogenic properties of some air pollutants pose a significant threat to lung health [1].

Many countries and international organizations have set air quality standards to limit the concentration of pollutants in the atmosphere. Compliance with these standards is crucial to protect public health. Governments and industries must work together to reduce emissions from vehicles, power plants, and factories through technological advancements and stricter regulations. Raising public awareness about the detrimental effects of air pollution on lung health can foster behavioral changes and promote advocacy for cleaner air [2].

Discussion

Implementing green spaces, urban trees, and sustainable urban planning can help mitigate air pollution and improve respiratory health in urban environments. As non-invasive ventilation techniques continue to evolve, their applications are expanding to specific patient populations, offering new treatment options and improved outcomes. On-invasive ventilation has shown to be effective in managing acute exacerbations of COPD. It can reduce the need for intubation, decrease mortality rates, and shorten hospital stays, particularly when initiated early in the disease progression. Cardiogenic Pulmonary Edema: NIV is increasingly used as a first-line treatment for patients with cardiogenic pulmonary edema. It helps alleviate respiratory distress, reduces the work of breathing, and improves cardiac function by reducing preload and afterload [3].

Non-invasive ventilation can be used as a preventive measure in highrisk surgical patients to reduce the incidence of post-operative respiratory failure and associated complications. Immunocompromised patients, avoiding invasive mechanical ventilation is crucial to reducing the risk of ventilatorassociated infections. Non-invasive ventilation can provide adequate support while minimizing the risk of complications.

The advancements in non-invasive ventilation are supported by a growing body of evidence demonstrating its effectiveness in managing acute respiratory failure. Numerous meta-analyses have shown that NIV reduces the need for intubation, lowers mortality rates, and shortens hospital stays compared to invasive mechanical ventilation in specific patient populations. Several RCTs have compared non-invasive ventilation to standard oxygen therapy or invasive ventilation, consistently demonstrating the benefits of NIV in various clinical scenarios. Studies have reported favorable long-term outcomes for patients treated with non-invasive ventilation, including improved quality of life and functional capacity [4-6].

Conclusion

Air pollution in urban environments has a profound impact on lung health, leading to increased risks of respiratory diseases and exacerbation of existing conditions. The evidence from epidemiological studies emphasizes the urgency of adopting effective regulatory measures and interventions to reduce air pollution levels. Protecting lung health is essential for the well-being of urban populations and requires collaborative efforts from governments, industries, and individuals to build sustainable and clean cities for future generations.
