METHOD OF DETERMINING MINUTE VOLUME OF LUNG VENTILATION IN CARRYING OUT INTRAOPERATIVE ARTIFICIAL LUNG VENTILATION IN ABDOMINAL SURGERY Russian patent published in 2012 - IPC A61B5/87 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to anesthesiology and resuscitation. Height (H) and weight (W) of patient's body are determined, area of body surface is calculated by formula S=0.0235·H^0.42246·W^0.51456. 2 hours before pre-medication duration of threshold apnea is determined. If apnea value is lower than 30 seconds, correspondence of correction coefficient 0.7 l per min per m² of body surface area is determined. If value of arbitrary threshold apnea is 31-60 seconds, correction coefficient is determined - minus 0.3 l per min per m² of body surface area. If value of arbitrary threshold apnea is more than 60 seconds, correction coefficient is determined - minus 0.55 l per min per m² of body surface area. After that required minute volume of ventilation (MVV) is determined by formula: MVV= (m/10+1)+k×S, where m is patient's weight in kg, S is area of body surface in m², k is correction coefficient.

EFFECT: method makes it possible to reduce quantity of complications associated with gas exchange irregularities.
