When asthma peak flow meter is at green level and there is wheezing would it still be asthma probable cause or something else ? can peak flow green still wheeze ?

Obtain the best of three measurements, and the green zone of the peak flow meter indicates airflow in the larger airways. The other aspect though is how you actually feel and if you hear wheezing, small airway function may be compromised. Continue your asthma action plan, and a medication adjustment may be discussed with your provider or by virtual consult with HT. Continue to monitor breathing.
