Lung Testing

Abraham Ishaaya MD


Pulmonary function tests (PFT’s)

PFTs are non-invasive breathing tests done to measure how well the lungs perform. More specifically, these tests are used to:

  • Measure your lung volume, the strength of your diaphragm and the airflow to & from your lungs.
  • Compare your lung function with standards that show how well your lungs should be working.
  • Detect narrowing in the airways.
  • Diagnose certain types of lung disease (such as asthma, bronchitis, and emphysema)
  • Find the cause of shortness of breath
  • Measure the effect of chronic diseases like asthma, chronic obstructive lung disease (COPD), or cystic fibrosis on lung function.
  • Identify early changes in lung function that might show a need for a change in treatment.
  • Measure whether exposure to chemicals at work or home affects lung function
  • Check lung function before someone has surgery
  • Assess the effect of medication
  • Measure progress in disease treatment

These non-invasive breathing tests are done during one appointment, and most often can be done on the same day as your medical consultation. You will be asked to breath into a tube that is connected to a machine. Our PFT technician will give you specific instructions on how to do these tests. It may take an effort to do these tests, and you may become tired or light-headed. To get the most accurate results from your breathing tests:

  • Do not smoke for at least 1 hour before the test.
  • Do not drink alcohol for at least 4 hours before the test.
  • Do not exercise heavily for at least 30 minutes before the test.
  • Do not wear tight clothing that makes it difficult for you to take a deep breath.
  • Do not eat a large meal within 2 hours before the test.

Some medications should not be taken before the test. Please check with us prior to your appointment.
