Taking Several Medications For Asthma, Still Having Symptoms. Possible To Have Normal Oxygen Level But Co2 High?

I have asthma, and have been having trouble with it. They have me on loads of medication, but I still have symptoms. My o2 level doesn't drop below 93, but I have time of sweating, confusion, weakness, and feeling like I am going to faint. Especially with excersize. Is it possible to have a normal o2, but your co2 be too high?

Hi,

Yes with exercise the tissue will produce more of CO2 which leads to increase in CO2 content but the O2 may be good in blood (artery) due to increased respiration.
You should do regular breathing exercise for at least 30min - 1 hour which will help you and also should carry short acting bronchodilator always with you. If you can upload the drugs with dose and the frequency and history of illness, it will be better to discuss in detail.
