Authors suggested improving practical skills of knitting the surgical node on their own developed simulator. 11 residents and 5 young cardiosurgeons participated in the project. The project was separated into 3 stages: 1st stage strated on September the 4th ,when theoretical preparation, demonstration of knitting techniques, possible errors discussion and the process of measurement of the number of knots while knitting per minute took place. The 2nd stage started on the October 11th when the first control measurement of the number of nodes after a month of training took place. The 3rd stage started on the November 3rd when the second control measurement took place. At all stages, blood pressure (BP) and heart rate were under control in all 16 learning participants under the investigation. If during the first phase of the project, average number of knots ranged from 8 to 70 per minute (on average 35,563 ± 17,049), the knots were of poor quality, so they tore and tangled in most cases. Competition between residents, excitement, uncertainty and haste could underlie those results. AP ranged from 90/60 to 125/80 mm Hg (on average 99,688 ± 10,562 / 67,188 ± 6,047) before the test, but immediately after the highest AP reached 150/85 mm Hg (the average 117.5 ± 15.275 / 76.25 ± 4, 655 mm Hg) p = 3.837 / 4.75. The pulse before the test was 69,125 ± 5,807 beats per minute, and after the study it increased to 89,875 ± 10,77 beats per minute (p = 6,784) with a difference to a statistical extent (p<0,01). In a month, repeated measurement of time and number of knots showed that the residents became more confident, calm and less emotional. They did not tear the threads, they were not disturbed and distracted while being watched by the other students and a mentor. The number of connected nodes increased from 26 to 80 per minute (an average of 48.375 ± 12.68 per minute). At the second stage, AP increase was not significant , so before the test , the average was 97,813 ± 8,159 / 66,25 ± 4,655 mm Hg, and after the test it was 102,5 ± 8,563 / 70,0 ± 5,774 mm Hg.t. (p = 1.585 / 2.023). The heart rate remained similar before and after the test, in particular, 67,688 ± 4,27 beats per minute.
