A few words of thanks would be greatly appreciated.

Respiratory function tests - Definition


Respiratory function tests are a series of tests to assess the quality of the gas exchange between the air and the blood in the lungs, as well as the capacity of pulmonary performance. They are useful for making diagnoses or enabling the recovery from lung and bronchial diseases, sometimes given before a general anesthetic. Respiratory function tests consist of several tests, including measuring the volume during respiratory movements, testing the capacity of each lung, and measuring the concentration of gases in the blood.
