monitor the effects of the drug. The initial effect of the drug can be seen at 1.5 - 2 minutes, the maximum
effect is observed at 5 minutes. Then, gradually, the effect of the drug diminishes. 

To study the details of the impact of the drug, a contour analysis is carried out. 

Contour analysis of the baseline pulse waves indicates that 

RI

 is 32.0%, and 

AIp75

 is -16.8%. 

By the 7th minute, the contour analysis shows marked changes due to nitroglycerin administration. RI
decreased to 14.3% and AIp75 decrease to -25.7%. Due to the effects of the drug, the patient's 

vascular

age

 decreased from 32 to 19 years.
