3. An Estimation Of Streams Of Air Of

3. An estimation of streams of air of type a loop-volume (analogue 1 = FEV1) Graphic record of simultaneously received Lung volume for the first second of the forced exhalation can be It is useful to full representation about a condition of pulmonary function, but Most precisely this indicator reflects a condition of obstruction of the top Respiratory ways. 4. Diffuzionnaja function of lungs. The condition of this function depends on qualities alveolar and capillary Surfaces of membranes, and as from a condition blood and Conditions of blood circulation limits of a small circle. This indicator Allows to estimate an effective alveolar exchange of oxygen and Carbonic gas with the external air environment. 5. Gases blood (the arterial!). Kislotno-alkaline balance and alveoljarno-arterial gradient on To oxygen can be calculated as And - (a gradient in room air) Can be estimated approximately as (150 - pCO2*1.25) - arterial pO2. This gradient And should be less than 9 for age of the patient of 20 years, And for age of 80 years - less than 24.
