Emphysema Breathing
- Explain the physiological reasons for the lung volumes and capacities that changed in the spirogram for this condition.
Acute Asthma Attack Breathing
- Explain the physiological reasons for the lung volumes and capacities that changed in the spirogram for this condition.
-How is this condition similar to having emphysems? How is it different?
-Emphysema and asthma are called obstructive lung diseases as they limit expiratory flow and volume. How would a spirogram look for someone with a restrictive lung disease, such as pulmonary fibrosis?
-What volumes and capacities would change in this case, and would these values be increased or decreased?
-In an acute asthma attack, the compliance of the lung is decreased, not increased as it was for emphysema, and air flows freely through the bronchioles. Therefore, will the FEV1/FVC percentage be less than normal, equal to normal, or higher than normal?
Acute Asthma Attack Breathing with Inhaler Medication Applied
- Explain the physiological reasons for the lung volumes and capacities that changed in the spirogram with the application of the medication.
- How much of an increase in FEV1 do you think is required for it to be considered significantly improved by the medication?
Breathing During Exercise
- Which volumes changed to most and when?
- Compare the respiratory rate during moderate exercise with that seen during heavy exercise.

Does this help? :down:

Yes that helped a lot. Thank you :D
