The Gas Structure Of Blood Is Changed A

The gas structure of blood is changed a little and seldom. At 2nd degree of respiratory insufficiency The short wind is shown at insignificant physical activity (the quiet Walking on an equal surface). At patients strongly pronounced ("warm" ) which amplifies At cooling, physical activity. - livid colour Mucous, nail boxes, skin. Appears at saturation decrease Haemoglobin oxygen on 6-8 % (to size about 90 %) or more than On 5gr\dL. Pressure of oxygen in arterial blood decreases to 60 pressure of carbonic acid in blood to 40 also increases and More. Develops respiratory , however blood remains in Norm limits (compensated respiratory ). Increase and development respiratory Leads to occurrence of cerebral symptoms (a headache, Dizziness, irritability, sleeplessness), mental infringements (Depression, drowsiness), a delay of a liquid owing to strengthening carbonic acid and sodium in kidneys leads to a proof tachycardia In rest. The same it is possible to tell rather and in conditions reduced pressure of oxygen in External air: the big height in mountains and by the plane; the insufficient Ventilation of lungs; the serious form of an anaemia; the voluntary Hyperventilation; a number of neurologic diseases (for example, insufficiency, an infection, a trauma, a tumour, etc.
