METHOD OF SELECTING OPTIMAL TIDAL VOLUME DURING GENERAL ANESTHESIA IN CHILDREN AGED 3-8 YEARS Russian patent published in 2024 - IPC A61B5/87 A61M16/00 

FIELD: medicine; anesthesiology; resuscitation.

SUBSTANCE: invention can be used to select the optimal tidal volume (TV) during general anesthesia in children aged 3 to 8 years. The initial setting of TV is 8–9 ml/kg. Then the level of CO₂ in the exhaled air is measured. With normal and increased CO₂ values, TV value is increased by 10 ml for 1 minute. The CO₂ level is re-evaluated. When CO2 decreases, this TV is optimal and TV is not increased. If the elevated CO₂ level remains, TV is increased by another 10 ml and the CO₂ level is assessed. A stepwise increase in the TV value by 10 ml is performed until the level of CO₂ in the exhaled air decreases below 45 mm Hg.

EFFECT: invention makes it possible to accurately select the physiological value of TV, ensuring the removal of CO₂ in accordance with its formation in the body.
