Modified Stange test gives new gynecological criteria and recommendations for choosing caesarean section childbirth.

Pregnancy and childbirth often threaten the life and health of the fetus. The greatest threat to the fetus during these periods is intrauterine hypoxia. The threat of intrauterine fetal hypoxia increases during natural childbirth and decreases during caesarean section.

COVID-19 causes non-specific pneumonia, which has become a new cause of hypoxia, leading to the death of many patients. Today, there are no effective drugs that provide an urgent increase in blood oxygenation. Therefore, it is urgently necessary to develop drugs to increase blood oxygenation in order to save the lives of patients with the new coronavirus infection.
