Tests of gas exchange function

  • G. J. Gibson


The exchange of oxygen for carbon dioxide depends on several physical and chemical processes and its degree of success is determined by their overall integration. If, to take the extreme case, all the ventilation were to go to one lung and the total perfusion went to the other, no gas exchange would occur. The importance of matching ventilation to perfusion and their capacity for adjustments was recognised by Haldane and other pioneers in the field and the effect of compensatory changes in local ventilation and/or perfusion in diseased lungs is often to minimise the functional consequences of structural damage.
