Cardiovascular Function and Pulmonary Gas Exchange
There has currently been an increased awareness of the clinical importance of the close anatomic and functional interdependance of the heart and the lungs, particularly in patients with acute respiratory failure . Of course the role of the cardiovascular system in the transport of respiratory gases from and to the tissues had been defined long ago . But it is now better appreciated that disturbances in lung and thorax mechanics markedly influence the function of the heart [3, 4], and also that changes in pulmonary blood flow and vascular tone are associated with significant modifications in gas exchange .
