Pressure Of Carbonic Acid In Blood (PaCO2) In

Pressure of carbonic acid in blood (PaCO2) in Normal conditions it is strongly supported in a range 39-41 mm Hg. On Ventilation of lungs influence and PaCO2, PaO2 and Indicators pH located in a trunk of a brain, which in commonwealth with Nervous impulses from receptors of a stretching of a lung and impulses from Fabrics of a bark of a brain operate breath biomechanics. Refusal of any of these Mechanisms leads to hypoventilation development, and . alveoluses a venous stream of blood from Pulmonary capillary network allows a pulmonary fabric to participate in Gas exchange of an organism. The gas exchange includes delivery of oxygen to To capillary bed and elimination 2 from a blood stream in a small circle Blood circulations. Effective and long removal 2 from blood depends From adequate ventilation of lungs. Relations between ventilation and PaCO2 Can be presented as follows: PaCO2 = (k) (VCO2)/VA. In Which VCO2 is a metabolic stream (manufacture) 2 (that Is, maintenance 2 in a blue blood), k - a constant and VA - speed Alveolar ventilation.
