A look at the kinds of Pulmonary function tests

by Anuj Oza Hospital Equipment Provider

Pulmonary function tests (PFTs) include diverse kinds of breathing examinations that gauge how well your lungs exchange air. Your lungs help you take air in (gasp) and respire air out (exhale). There are many diverse kinds of PFTs done on equipment built by PFT Machine Manufacturers. Some also calculate how well your lungs engross oxygen into your blood and how workout affects your lungs.

  • Lung volumes or body plethysmography. Lung capacities or body plethysmography gauge the various amounts of air that are in your lungs after different points of breath and exhalation.

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

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

After recording your data, your healthcare provider will take you to a room with PFT apparatus bought from a PFT Machine Dealer and give you instructions according to your examination.


A healthcare supplier will first put soft fasteners on your nose. The nose fasteners safeguard that you respire through your mouth, not your nose.

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

Body plethysmography

A healthcare provider will put on your nose fasteners, and you’ll be seated in the clear box. Your supplier will close the entrance. The entrance remains closed for about five minutes.

Tell the healthcare supplier if you’re uncomfortable in confined spaces (claustrophobic). They can support you feel more content during the examination.

You’ll place your lips around the mouthpiece, and the supplier will give you instructions on breathing in and out.

As you respire, the spirometer will notice pressure or volume changes in the box to support measuring your lung volume.

Gas diffusion study

Your healthcare supplier will put on your nose fasteners.

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

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

What are the dangers of pulmonary function testing?

Pulmonary function testing is harmless. But you may feel faint, lightheaded, or exhausted from breathing so deeply. You may also cough from puffing into the mouthpiece or feel tired from training. These indications should go away soon after you complete the PFT.
