Answer:
The best indicator of the effectiveness of the albuterol is an increase in peak expiratory flow rate.
Step-by-step explanation:

As there is greater exchange of air , it is reflected as a higher peak expiratory flow rate.
Hence The best indicator of the effectiveness of the albuterol is an increase in peak expiratory flow rate.
