You are working in cardiopulmonary rehabilitation. It is your patient, Dave’s, first day of rehab. Dave had a heart attack 45 days ago. He is 40 years old and feels comfortable and confident enough to walk on a treadmill or ride a bike. Upon talking with Dave, you learn that he regularly exercised up until his heart attack. He completed resistance training 3 days/week at his local gym and would play tennis with friends several days each week. He can walk comfortably without an assistive device on flat surfaces at his own speed. You need to determine Dave’s VO2 in order to create a correct exercise prescription.
