Hi, -- sorry you are having trouble communicating with your husband when it comes to oxygen levels. Asthma is so multi-layered and it can be hard for people to wrap their minds around, especially if they don't have asthma themselves.
I thought this article from one of our respiratory therapists might be useful in your continuiing conversations:

The key thing for both of you to remember is that each person is different. Some people are more sensitive to changes in oxygen saturation. As you'll see in that article, it can be common for a person in the middle of an asthma attack to have "good" looking numbers on the oximeter. And yet there they are, having intense difficulty breathing! Your experience is real and valid.
The 94% reading is still within the "normal" range -- but, again, you have asthma and I am assuming your husband does not. It's like if two people the same size went hiking, and one got tired quicker than the other. We are all in different places regarding our health.
Has your husband come with you to your doctor's appointments lately? It may be helpful for him to hear directly from your doctor about the way yur asthma is affecting you. At least I hope so!
Hang in there. We are always here to support you and I hope you'll keep us up to date. Take care!
