Does the use of the abdomen during inspiration alter gas exchange to the bases of the lungs? Most previous investigators have concluded that this technique does not affect regional ventilation. However, if gas concentrations are used as an index of gas exchange, if the subject has normal lungs, is seated and performs the maneuver with the assistance of a physiotherapist, the answer is an unequivocal yes. This study does not pinpoint the exact mechanism by which this alteration is accomplished, but suggests that changes in thoracoabdominal shape influence regional blood flow. It does not indicate whether this effect is beneficial or detrimental. Whether the large number of patients with obstructive lung disease who attempt this maneuver in an unsupervised manner alter gas exchange in any way is uncertain. However, the data do suggest that some patients might be affecting their lung function, and we should learn more about the precise mechanisms. |
