Abstract

As is known, there is a close relationship between blood circulation and respiration, which is what some functional tests are based on. According to Einbrod, with frequent and shallow breathing, the aortic pressure does not change; deep breathing causes fluctuations in blood pressure (Borisova and Lyass). Henderson speaks about the connection of hyperventilation with blood pressure as early as 1908 (citation. by Holden and Priestley). He managed to induce shock in animals by prolonged hyperventilation of the lungs. With increased ventilation, CO2 is washed out, its content in blood and tissues decreases, as a result, alkalosis occurs, causing changes in blood circulation.
