Later, Right Extends, Becomes (=) And On To

Later, right extends, becomes (=) and on To partition ultrasonic effect waves develops so-called. Doppler an echocardiography is most Reliable noninvasive method of an estimation of pressure in a pulmonary artery (PA). Patients with a hypertension of a pulmonary artery can have signs Functional the valve. Maximum Speed (TR) can be registered and from it Pays off on equation Bernoulli PAsyst = (4 X TR) + RAP. Where RAP - pressure in the right auricle, measured in the bottom hollow vein (IVC). Other tests and researches and similar researches of volumes of ventilation of lungs These measurements are required for diagnosis specification Obstructive syndrome of illness of a lung and estimation of gravity of a syndrome. In practice it is most often used Indicator 1 (FEV1) and an index of a barrier to air stream - the relation 1 / . And their dynamics can document measurements of volumes Increase (TLC) capacity of a lung, the functional residual Capacities of lungs (FRC) and residual volume of lungs (RV), specifying on Progress of an obstructive syndrome.
