How to work Pulmonary and it’s function

Pulmonary function analyzers are designed to assess volume, airflow and expiratory parameters through the respiratory tract of adults and older children. These usually include a spirometry instrument  

a computer, a gas analyzer and an electronic unit with computerized capabilities and appropriate software. 

In addition to diagnostic spirometer measurements, they may measure parameters such as functional residual capacity, diffusing 

capacity of the lungs for carbon monoxide, and airway resistance. The analyzers are intended to provide a baseline for ventilatory 

function as well as identify respiratory impairments. Some systems include a total-body plethysmograph for measuring lung volume and Raw. 

This test is done by having you take in a deep breath and then, as fast as you can, blow out all of the air. You will be blowing into a tube 

connected to a machine (spirometer). To get the “best” test result, the test is repeated three times. You will be given a rest between tests.
