Compared with the normal patient, what happened to the FVC in this patient? Compared with the normal patient, what happened to the FEV1 in this patient? Compared with the normal patient, what happened to the FVC in this patient? Compared with the normal patient, what happened to the FEV1 in this patient?
09/30/15 page 3 Which values in this spirogram have notreturned to those of the normal patient (select all that apply)? You correctly answered: c. IRV d. RV e. FVC g. FEV1 For both types of exercise, the tidal volumes and breathing rates were increased. Compared with normal values, did tidalvolume or breathing rate increase more during moderate exercise? (Determine the percentage by which each valuechanged.)

09/30/15 page 7 Post-lab Quiz Results You scored 100% by answering 5 out of 5 questions correctly. 1. Which of the following respiratory values represents a decreased flow rateduring the obstructive lung disease(s)? 2. Calculate the ERV of an individual with the following respiratory volumes: TLC = 6000 ml, FVC = 4800 ml, RV = 1200ml, IRV = 2900 ml, TV = 500 ml. 3. Calculate the FVC of an individual with the following respiratory volumes: RV = 1000 ml, IRV = 3000 ml, TV = 500 ml,ERV = 1500 ml. 4. What is the largest volume for the normal patient? 5. What happened to the RV for the emphysema patient and the asthmatic patient?
09/30/15 page 8 Review Sheet Results 1. What lung values changed (from those of the normal patient) in the spirogram when the patient with emphysema wasselected? Why did these values change as they did? How well did the results compare with your prediction? 2. Which of these two parameters changed more for the patient with emphysema, the FVC or the FEV1?
