The air we breathe has a quality. But with Karachi’s Air Quality, it is becoming dangerous as the days pass by.
AQI values at or below 100 are generally thought of as satisfactory. When AQI values are above 100, air quality is unhealthy: at first for certain sensitive groups of people, then for everyone as AQI values get higher. The AQI is divided into six categories. Good, Moderate, Unhealthy for sensitive groups, Unhealthy, Very healthy, and Hazardous!
For a week now, Karachi’s air quality has significantly become hazardous. And with COVID-19 second wave, the dangers have increased!
The ground-level ozone is disturbed due to massive smoke production with particle pollution also known as particulate matter, including PM2.5 and PM10.
Carbon monoxide, Sulfur dioxide, and Nitrogen dioxide present in the air makes it difficult to breathe for a normal person with a healthy set of lungs. The catastrophy is bigger for COVID-19 patients.
The current target oxygen saturation range for patients with COVID-19 recommended by the National Institutes of Health is 92–96%. And with the Hazardous air quality in Karachi the breath ratio comes down to a dangerous 15%.
How to Protect?

-Wear a mask outside to avoid excessive contamination
-Run an Air Purifier
-Close windows and doors
-Avoid outdoor exercises.
Be safe, be protected!
