A 10-year-old boy is brought in by his parents with increasing breathlessness. He was diagnosed with asthma about 2 years ago and has been on treatment since then. He was initially observed to have breathlessness, cough and chest tightness 2 or 3 times a week. He would wake up once or twice a month in the nighttime with breathlessness. At that time, his pediatrician started him on a Ventolin inhaler to be used during these episodes. His symptoms were well controlled until a few months ago when he started to experience increased nighttime awakenings due to breathlessness. He is unable to play outside with his friends as much because he gets winded easily and has to use his inhaler almost daily to help him breathe easier. He is able to walk and perform other routine activities without difficulty, but playing or participating in sports causes significant struggles. Based on his symptoms, his pediatrician adds an inhaled formoterol and budesonide combination to his current regime. During spirometry, which of the following peak expiratory flow rates will most likely be observed in this patient?
