Pulmonary Function (PFT)

Common types of PFTs are spirometry, diffusion studies and body plethysmography, which are each procedures conducted in order to determine how well you move air in and out of your lungs and how efficiently oxygen enters your bloodstream.

According to the American Thoracic Society, PFTs can be used to:

Compare your lung function with known standards that show how well your lungs should be working.
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.
Detect narrowing in the airways.
Decide if a medicine (such as a bronchodilator) could be helpful to use.
Show whether exposure to substances in your home or workplace may have harmed your lungs.
Determine your ability to tolerate surgery and medical problems.

Why does cold air make it harder to breathe?

Cold, dry air can irritate the airways and cause them to tighten, especially for patients with asthma or other lung conditions. This can lead to shortness of breath, coughing, or chest discomfort during colder months.

Can dry air or using a humidifier affect my lungs?

Yes - both overly dry air and excess humidity can impact your respiratory system. Dry air may irritate your airways, while too much humidity can promote mold or allergens. Finding the right balance is important for lung health.

Can strong smells or odors trigger breathing problems?

Certain odors, chemicals, or environmental irritants can trigger symptoms like coughing, wheezing, or shortness of breath, particularly in individuals with asthma or sensitive airways.

What are the most common signs of sleep apnea?

Common symptoms include loud snoring, gasping during sleep, daytime fatigue, morning headaches, and difficulty concentrating. Many patients don’t realize they have sleep apnea until evaluated by a specialist.

Do I need a sleep study if I snore?

Not everyone who snores has sleep apnea, but persistent or loud snoring - especially with other symptoms - may require a sleep study to properly diagnose and treat the condition.

When should I be concerned about a chronic cough?

A cough lasting more than 8 weeks is considered chronic and should be evaluated. It may be related to asthma, GERD, infections, or other lung conditions that require proper diagnosis and treatment.

Why do I feel short of breath even when resting?

Shortness of breath at rest can be caused by a variety of conditions, including asthma, COPD, anxiety, or other pulmonary issues. A thorough evaluation can help determine the underlying cause.

Can asthma develop later in life?

Yes - adult-onset asthma is more common than many people realize. Symptoms such as wheezing, coughing, and chest tightness should be evaluated, even if you’ve never had asthma before.

What does a pulmonologist treat?

A pulmonologist specializes in diagnosing and treating conditions affecting the lungs and respiratory system, including asthma, COPD, chronic cough, sleep apnea, and more.

What should I expect during my first visit?

Your first visit typically includes a review of your symptoms, medical history, and possibly diagnostic testing such as pulmonary function tests. This helps create a personalized treatment plan tailored to your needs.
