A peak expiratory flow rate of 40% below the patient's personal best indicates that the patient is still having difficulty moving air into the respiratory passages because of airway narrowing.The asthma is not responding sufficiently to the drug.Although the respiratory rate is slightly high,many conditions can cause this and it alone is not an indication of ineffective drug response.
