Reasons For Having PFTs
- See if there are issues with your lungs that could interfere with anesthesia (the medications used to make you sleepy).
- See how much air your lungs can hold.
- Diagnose lung disease
- Diagnose abnormal functioning of the lung
- Determine the amount of damage caused by abnormal lung functioning
- Check the status of chronic (long-term) lung disease
- The two major patterns of lung disease are obstructive and restrictive. In obstructive lung disease there is a decrease in the flow of air. Examples include emphysema or asthma. In restrictive lung disease the amount of air the lung can fill up with is limited. Examples are fibrosis or scarring.
- Radiation in the area of your lung(s)
- Some chemotherapy drugs
