Study of ejection fraction of professional divers during simulated diving in hyperbarism and various respiratory mixture.
This study was done to elucidate the influence of high pressure (5.5 and respectively 20.0 ATA) and various respiratory mixtures (nitrox and heliox) on cardiac output investigated (by the Ejection fraction) as in the medical literature there have not been found studies on the left ventricular performance of the divers under these conditions.
