Intelligent closed-loop mechanical ventilation control system based on ARDS lung protection strategy and method thereof

Abstract

The invention discloses an intelligent closed-loop mechanical ventilation control system based on an ARDS lung protection strategy. The system comprises a physiological ventilation parameter sensing subsystem, an intelligent closed-loop control subsystem and a ventilation adjustment execution subsystem. The physiological ventilation parameter sensing subsystem monitors breathing parameters of a patient in real time, then the optimal combination of the mechanical ventilation parameters is calculated through the intelligent closed-loop control subsystem at set intervals, and parameters of an ARDS patient breathing machine are adjusted through the ventilation adjustment execution subsystem. The system has the advantages that based on an acknowledged ARDS lung protection mechanical ventilationrule, both oxygenation and lung protection can be considered, therefore, a dynamic balance strategy is intelligently selected; specialized and personalized mechanical ventilation self-adaptive adjustment for the ARDS is achieved, lung and other organ injuries, caused by human factors such as insufficient experience and nonstandard operation, of the medical staff can be avoided, the optimal ventilation treatment effect is achieved, and the ARDS mechanical ventilation treatment efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the field of ventilators, and in particular relates to an intelligent closed-loop mechanical ventilation control system and method based on an ARDS lung protective strategy. Background technique [0002] Acute Respiratory Distress Syndrome (ARDS) is caused by intrapulmonary and extrapulmonary causes. It is a clinical syndrome caused by non-cardiogenic pulmonary edema. The main clinical manifestation is intractable progressive hypoxemia. rate has attracted much attention. The onset of ARDS is rapid, and it can occur within 24 to 48 hours, or as long as 5 to 7 days, and the mortality rate is 40% to 60%. [0003] At present, mechanical ventilation is the main means of treatment of ARDS. The main purpose of mechanical ventilation is to ensure proper oxygen supply to human tissues, so that organs and tissues can get enough oxygen for oxygenation to obtain energy, while ensuring sufficient removal of carbon dioxide to avoid respira...

AI Technical Summary

Problems solved by technology

Although the above patents use closed-loop control strategies to achieve automatic adjustment of mechanical ventilation-related parameters, these are not designed for the treatment of ARDS diseases, and lack the consideration of trade-offs between lung protection ventilation strategies and oxygenation enhancement.

There is currently no patent on optimal mechanical closed-loop automatic ventilation based on the trade-off between lung protection and oxygenation in ARDS patients
