Exacerbation of Symptoms: Exposure to poor air quality can lead to acute exacerbation of COPD, a severe condition marked by a sudden worsening of symptoms. This often necessitates hospitalisation and can be fatal if not addressed promptly.
Increased Inflammation: Pollutants like PM2.5 and NO2 have been shown to increase pulmonary inflammation, thereby worsening COPD. A study published in the journal "Chest" found that long-term exposure to air pollution leads to significant increases in COPD-related hospital admissions.
Reduced Lung Function: Continuous exposure to poor air quality can lead to a faster decline in lung function among COPD patients, as revealed by the European Community Respiratory Health Survey.
Compromised Immune Response: Toxic air can impair the lungs' natural defense mechanisms, making COPD patients more susceptible to respiratory infections, which are particularly dangerous for them.
Strategies for COPD Patients
Limit Outdoor Exposure: Avoid going outdoors during times when the AQI is high. If outdoor activity is unavoidable, try to limit the duration and intensity of the exposure.
Indoor Air Purification: Use air purifiers with High Efficiency Particulate Air (HEPA) filters to remove airborne particles. Keep windows closed to prevent the ingress of outdoor pollutants.
Ventilation Management: Properly ventilate the home during times when outdoor air quality is good. Use exhaust fans in the kitchen and bathroom to remove indoor air pollutants.
Face Masks: Utilise N95 respirators when stepping outdoors, especially during smog or haze.
Regular Medication: Always keep prescribed medications accessible. Utilise long-term control medicines as prescribed by your healthcare provider.
Emergency Preparedness: Have an exacerbation action plan outlined in consultation with your healthcare provider. Keep an emergency kit that includes medications, nebulizers, and important contacts.
Exercise Indoors: Opt for indoor exercise regimens like treadmill walking, stationary cycling, or guided breathing exercises.
Nutritional Support: Maintain a balanced diet rich in antioxidants, which can help in combating oxidative stress induced by pollutants.
Regular Health Check-ups: Regular visits to healthcare providers for lung function tests and medication adjustments can aid in better management of COPD in the face of poor air quality.
Educational Empowerment: Equip yourself with knowledge about the latest research and recommendations on COPD management through trustworthy medical journals and consults with healthcare providers.
