If pO2 - <80 mm Hg, - Arterial distinction on oxygen is increased also therapy by oxygen not Corrects a situation-follows to specify suspicions about shunting (at Normal pCO2). pO2 - <80 mm Hg, - arterial Distinction of oxygen is increased also therapy by oxygen corrects a situation, Ventilation of the patient "does not correspond to a blood stream in lungs". The Ventilation index (IV) = the Ventilating index = (PaCO2 in mm Hg) * (frequency of breath in Minute) * (the maximum pressure of air upon a breath in cm H2O) / 1000 Interpretation: the above a ventilation index, the worse ventilation. The third degree of respiratory insufficiency It is characterised by occurrence clinical and obvious Signs of pulmonary heart.
