Rice. 1. Type I reaction to a hypoxemic test. EKG - I hole, BCG and a curve of respiratory movements were registered simultaneously. a - before the test, there are no changes in the ECG and BCG. 6 - 15 after the test, there is an increase in heart rate and an increase in systolic and diastolic waves of BCG.

Rice. 2. Type II reaction to a hypoxemic test. a - before the test, the Ti wave in the ECG is flattened; in BCG - the regularity of the complexes is preserved both during inhalation and exhalation, although the total voltage of the curve is reduced. b - 15 after the test, the BCG significantly worsened and represents the III degree of pathological abnormalities according to Brown.
