The remarkable vasomotor reaction of the blood circulation to changes of the arterial CO<sub>2<\/sub> value has been known for many years due to examinations with indicator methods. The first examination virtually delivered the same results as previous CBF (cerebral blood flow velocity) examinations. To this examination, the TCD method was applied to determine the vasomotor reactivity in a normal state of health. Since then, Doppler has established itself as an instrument to determine the vasomotor reactivity and reserve. The most common vasomotor reactivity tests are included in this software.<\/p>\n<p>&nbsp;<\/p>\n<p>The non-invasive determination of cerebral autoregulation is useful in developing strategies for its improvement. In addition, it can help control the intracranial pressure (ICP) and maintain optimum cerebral blood circulation.[\/vc_column_text][vc_separator type=&#8221;transparent&#8221; up=&#8221;10&#8243;
