Respiratory Disorders: Asthma Severity,Triggers, and Medications

JR is a 56 yo man with h/o asthma, HTN and hyperlipidemia. He presents to the ER today with h/o shortness of breath for 45 minutes at rest. He reports that he was feeling well and in his usual state of health until about an hour ago, when he smelled something burning. 20 minutes later, he began to feel short of breath and was wheezing. He tried using his albuterol inhaler without success, so he proceeded to the ER. Upon arrival, he was tachycardic, tachypneic, wheezing, using accessory muscles and hypertensive. His last admission for an asthma attack was 2 months ago. He denies a recent cold or URI and says the albuterol usually helps him when he feels an attack coming on and tends to use it on a daily basis. He generally has wheezing and shortness of breath on a daily basis. JR reports poor sleep due to waking about 2 times a week for shortness of breath. He has 2 cats, which sleep next to him on his pillow and he lives in an apartment complex. JR does not smoke, but his neighbor smokes. JR is a carpenter by occupation. He monitors his peak flow once a week at home. He reports that his peak flow generally runs about 325 L/min and his personal best is 480 L/min. His current peak flow is 175 L/min.
