Got an O2 monitor and I tried it. It said 98. And I just used my albuterol/rescue inhaler and I still feel chest pressure and I’m coughing. Guess that’s the asthma reacting to the albuterol. My peak flow meter where you blow into a tube and it gives you a number was 350. It’s supposed to be 400 but bad would be like 200. And this is right after I took my albuterol.
