What happens the oxygen and carbon dioxide blood levels during asthma?

During an asthma attack, the airways in the lungs become inflamed and narrow, making it difficult for air to flow in and out. This can lead to several changes in blood oxygen and carbon dioxide levels.

Oxygen levels: During an asthma attack, the oxygen levels in the blood can decrease. This is because the inflamed and narrowed airways make it harder for oxygen to reach the lungs and be absorbed into the bloodstream. As a result, the body may not get enough oxygen, which can lead to symptoms such as shortness of breath, wheezing, and chest tightness.

Carbon dioxide levels: During an asthma attack, the carbon dioxide levels in the blood can increase. This is because the inflamed and narrowed airways make it harder for carbon dioxide to be exhaled from the lungs. As a result, carbon dioxide can build up in the bloodstream, which can lead to symptoms such as confusion, drowsiness, and headaches.

In severe cases, low oxygen levels and high carbon dioxide levels can be life-threatening and require immediate medical attention.
