Approximately 20 % Of Patients With COPD And

Approximately 20 % of patients with COPD and normal arterial pressure of oxygen in blood have night, not connected with oxygen insufficiency. Pulmonary blood circulation - Usually blood with low vascular resistance and high In capacity of pool of blood. Value of the high pulmonary arterial Pressure at consists that it increases an impedance (the specific Resistance) for right at the moment of exile. Excessive The increase in an impedance after loading often conducts to a sudden stop Hearts. Pulmonary arterial hypertension (LOG) It is defined as average pressure in a pulmonary artery () more than 25 mm Hg in rest or, at least, 30 mm Hg at the physical To loading. Increases it is almost always connected with increase of the pulmonary Vascular resistance (PVR) and average pulmonary pressure Jammings. Pressure of the right is thus final-diastolicheskoe for acknowledgement of the diagnosis the LOG should be less than 15 mm Hg. Thus, continuous eminence and PVR Causes an overload and a stop right and conducts to Inability of heart to support blood circulation with the subsequent death The patient.
