METHOD FOR DIGITAL AND VISUAL MONITORING OF INTRATRACHEAL PRESSURE BY A BED MONITOR DURING ARTIFICIAL PULMONARY VENTILATION Russian patent published in 2019 - IPC A61M16/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to intensive care, and can be used in artificial pulmonary ventilation (APV). Transducer for invasive monitoring and an infusion line are used. Latter is shortened to 50–60 cm. Distal end of the infusion line is inserted through the sanative port on the respiratory circuit adapter and the intubation or tracheostomy tube into the trachea, and the proximal one is connected to a transducer located as close to the patient's bed and strictly as the trachea. On a bedside monitor with an invasive pressure monitoring option, a sweep speed of 25 mm/s and a measurement scale of 0–20 mm Hg are set. After the system is reset, the intratracheal pressure is measured and visual observation of the pressure curve is monitored on the monitor. Herewith, three pressure values in the trachea are measured: maximum (Ppeak), minimum (PEEP) and average.

EFFECT: method enables accurate and affordable measurement of maximum (Ppeak), minimum (PEEP) and average intratracheal pressure in the APV process, as well as a visual analysis of the tracheal pressure curve by using a bedside monitor technique with an invasive pressure monitoring option, a transducer for invasive monitoring and an infusion line.
