ENT Doctor | Air Quality & Asthma: Things to Know

ENT Doctor | Patients with asthma have to think differently about stepping outdoors. There are many things to consider regarding air quality and the effect that the air could have on the ability to breathe easily. Consider these things that your ENT doctor wants you to know about air quality and asthma:

What Is AQI?

The Environmental Protection Agency (EPA) has daily information on air quality in areas with known poor air quality. The Air Quality Index (AQI) is measured based on the following items: ground-level ozone, particle pollution, carbon monoxide, sulfur dioxide, and nitrogen dioxide. Air quality can change quickly, sometimes even between morning and evening, and is always different from day to day and season to season. Cities of more than 350,000 people are required to report the daily AQI as well.

How Is AQI Measured?

The five criteria points are all measured and this measurement is converted to a number on a scale of 0 to 500. An AQI score of 50 or below means that the air quality is good and that there are no general health effects. A score of 50-100 is moderate and a few people may have some health effects. A score of 100-200 deems the air unhealthful and some people with asthma may have some aggravation. Scores of 200-300 mean that the air is very unhealthful and asthma patients should avoid being outside in this kind of AQI score. A score of over 300 is deemed hazardous and asthma sufferers should definitely not be outside at all.

What Is Ground-level Ozone?

Millions of people live in a town or city that has a very high level of ground-level ozone. This means that they are usually breathing air that has been polluted with chemicals from car exhaust and power plants. ENT doctors warn that warmer days make ground-level ozone worse which can be hard for those who want to get outside on a sunny day within a big city.

Air quality is an important aspect to keep in mind when dealing with asthma. Consider checking the air quality daily in order to be prepared for an asthma attack. Check with your ENT doctor at National Allergy and ENT in order to learn more about air quality and asthma.
