Reaction cardiovascular system to the hypoxic-hypercapnic trainings

The results of the effect of hypoxic-hypercapnic training to change the parameters of the cardiovascular system in individ-uals with ischemic changes in the heart muscle. The study involved 125 people aged 45 to 65 years, with signs of myocardial ischemia and deviations from the norm of the T wave and tidal train on the simulator hypoxic-hypercapnic type («Samozdrav»). It was found that the outcome of the examination subjects average РаСО2 equaled - 31.8 mm Hg. With this result, based on the percentage of myocardial perfusion, depending on РаСО2 it was 72% of normal, respectively, the lack of blood flow was 28%. After a course of respiratory training with hypoxic-hypercapnic gas mixtures for breathing simulator for 8 months and increased the level of РаСО2 of 37 mm Hg. Depending on the percentage of myocardial perfusion by РаСО2 seen that myocardial perfusion improved by 12% (p < 0,05). It is revealed that after a hypoxic-hypercapnic training in the subjects observed a decrease signs of ischemia and myocar-dial perfusion improved by 12%, as well as restoring the parameters of the T wave on the electrocardiogram to normal in 62% subjects. Thus, the results indicate that by using the simulator («Samozdrav») there was a strong tendency to increase the partial pressure СО2 in exhaled air, leading to normalization of arterial carbon dioxide - the most important regulator of blood flow and vasodilatation effect.
