What is a normal pulse ox reading for those with asthma?

Around 95%...: Between exacerbations, an asthmatic's pulse ox is normal since airway obstruction in asthma is reversible by definition. During an asthma exacerbation, the airways are obstructed/inflamed to a certain degree depending on the severity of the exacerbation and the pulse ox may decrease. Supplemental oxygen may then be necessary to maintain oxygen delivery to vital organs/tissues. ...Read more

I have allergic asthma. I feel really sick (dizziness, tight chest, cough) but I never have a pulse ox below 98 so PCPs don't take it seriously. Do I really need a $1K consult with a pulmonologist?

This is an everyday problem that we care for all the time. ...Read more

I have asthma and a pulse oximeter. I use it to check when I get an asthma attack. What Spo2 is normal? So I know when to go to the ER. I am 25.

When it gets worse: I agree with Dr Grieve that pulse oximetry is useless in monitoring asthma .The rule of thumb is symptoms . If you are waking up at night from asthma more than 2x/wk, using your rescue inhaler nearly daily, or the breathing is getting progressive worse, you need to see your doctor. Lung function monitoring helps but the readings do not always correlate with severity of your asthma. ...Read more

See below: A pulse ox of 92% indicates a moderate asthma attack. Pulse is normal. More importantly is wether or not your child is responding to treatment.
