What are the categories of Pulmonary Function Examinations?

by Anuj Oza Hospital Equipment Provider

Pulmonary function tests (PFTs) comprise different types of breathing examinations that measure how well your lungs exchange air. Your lungs help you take air in (pant) and respire air out (exhale).

There are many diverse kinds of PFTs. Some also compute how well your lungs engross oxygen into your blood and how exercise affects your lungs.

PFTs are harmless and don’t require a healthcare provider to put any apparatuses or instruments inside your body (non-invasive).

Another designation for pulmonary function tests is lung function examinations.

Lung function examinations comprise:

  • Spirometry. Spirometry gauge how much air you can gasp and respire. It also guesses how much air is in your lungs.

  • Lung volumes or body plethysmography. Lung volumes or body plethysmography gauge the various quantities of air that are in your lungs after diverse points of inhalation and exhalation.

  • Gas diffusion study. A gas diffusion study calculates how much oxygen and other airs transfer from your lungs to your blood.

  • Cardiopulmonary exercise test (CPET). A CPET determines how well your heart, lungs, and muscles effort while you’re exercising.

What is the most shared pulmonary function examination?

Spirometry is the most shared kind of pulmonary function test.

When is pulmonary function testing done?

Your healthcare provider may command pulmonary function examinations if you have lung or airway indications like cough or shortness of breath, are enduring surgery, or use tobacco products (smoke). These indications may include:

  • Chest tautness, pain, or pressure.

  • Coughing, particularly if you produce secretion or phlegm.

  • Trouble gasping or taking a deep breath.

  • Shortness of breath (dyspnea).

  • Wheezing.

Even if you don’t have indications, your healthcare provider may order a pulmonary function examination as part of a routine physical examination.

PFTs also support your healthcare provider:

  • Notice tapering in your lungs’ airways.

  • Recognize early variations in your lungs’ ability to transfer oxygen to your blood.

  • Calculate the effects of continued smoking on chronic pulmonary illnesses.

  • Resolve if medicines may help improve your breathing.

  • Comprehend if exposure to ingredients in your environment has affected your lungs.

  • Regulate your aptitude to tolerate surgery or other medical procedures.

How does pulmonary function testing function?

A pulmonary function test is moderately humble.

A PFT comprises a clear, airtight box, soft nose clasps, a mouthpiece, and a small electronic appliance made by PFT Machine Manufacturers that gauges your airflow (spirometer).

How do I formulate a pulmonary function examination?

Before your pulmonary function testing, your healthcare provider may request you to:

  • Halt taking your breathing drugs for a short period.

  • Wear slack, comfortable clothing that doesn’t squash your chest.

  • Duck any heavy exercise before your examination.

  • Evade using tobacco products before your examination.

These safeguards will help safeguard that you get accurate results from your PFT.

What must I imagine during pulmonary function testing?

After documenting your information, your healthcare provider will take you to a room with PFT apparatus bought from PFT Machine Dealers and give you orders according to your test.


A healthcare provider will first put lax clasps on your nose. The nose clasps to ensure that you respire through your mouth, not your nose.

You’ll put your maws around a mouthpiece, and the mouthpiece attaches to a spirometer. The provider will then give you instructions on exhalation in and out.

Body plethysmography

A healthcare provider will put on your nose clasps, and you’ll sit in the clear container. Your provider will shut the door. The door remains shut for around five minutes.

Tell the healthcare provider if you’re uneasy in restricted spaces (claustrophobic). They can help you feel more content during the examination.

You’ll put your lips around the mouthpiece, and the provider will give you instructions on gasping in and out.

As you respire, the spirometer will notice pressure or volume variations in the box to help measure your lung volume.

Gas diffusion study

Your healthcare provider will put on your nose clasps.

You’ll put your lips around the mouthpiece, and a healthcare provider will give you instructions on gasping in and out a small, harmless amount of carbon monoxide.

As you respire, the spirometer measures how much carbon monoxide you breathe out. This extent designates how much of the gas your lungs absorbed.

Cardiopulmonary exercise test

A healthcare provider will assign you to machines supplied by PFT Machine Suppliers that gauge your heartbeat, blood pressure, and blood oxygen. You’ll then walk on a treadmill or cycle a motionless bicycle.

The machines will gauge various aspects of your heart, lungs, and muscles during the test.

What must I imagine after pulmonary function testing?

After testing, you may resume any drugs your healthcare provider told you to stop taking. You can also return to your normal happenings, including exercise.

If you felt faint or giddy during the examination, the healthcare provider will monitor you until your indications go away and you can go home.

The healthcare provider will tell you when to expect your examination outcomes.
