FIELD: medicine.
SUBSTANCE: method for gas delivery during ventilation uses an artificial respiration system comprising a patient-tube system connected to the outlet of the gas delivery system to transfer gas to the patient during inhalations with addition of gas; a flow sensor connected to the said outlet for gas flow measurement, a patient-tube pressure sensor coupled to the said patient-tube system to measure the gas pressure therein and provide pressure signals in the patient-tube system representing the said pressure. The processor is connected to these sensors and is able to receive pressure and flow signals from them. According to the method, flow information from the said flow sensor is obtained in one sample, pressure information from the said patient-tube system pressure sensor is obtained in one sample and calculated for the said one sample based on the flow information from the said flow sensor and pressure information from the said patient-tube pressure sensor, the amount of gas necessary to compensate for the gas lost when creating excess pressure in the patient-tube system and the gas lost due to leakage in the patient-tube system. The compensated amount of gas based on the specified calculation is delivered. An artificial respiration system and a machine-readable medium storing the program for method implementation are disclosed.
EFFECT: provision of sufficient pressure to deliver gas into the patient's lungs.
