Electrical impedance imaging information acquisition device

Abstract

The invention provides an electrical impedance tomography information acquisition device, which is characterized by comprising an acquisition part and a monitoring part, the acquisition part is used for acquiring resistance information and transmitting the resistance information to the monitoring part; the monitoring part is used for imaging according to the resistance information and feeding back imaging information to the mechanical ventilation device; and the mechanical ventilation device is used for adjusting the gas output in real time. When mechanical ventilation is carried out on the respiratory distress patient, the lung parameters of the patient can be timely responded or rapidly fed back, so that the situation of mechanical ventilation related lung injury caused by too high or too low positive end-expiratory pressure in the mechanical ventilation process is reduced.

Description

technical field [0001] The invention relates to the technical field of electrical impedance imaging, in particular to an information acquisition device for electrical impedance imaging. Background technique [0002] Acute respiratory distress syndrome (ARDS) is a clinical syndrome characterized by refractory hypoxemia caused by intrapulmonary or extrapulmonary causes, and is a common respiratory critical disease that seriously threatens human health. As early as during the First World War, Pasteur defined the large area of ​​atelectasis caused by chest injuries in soldiers as pulmonary contusion; in 1945, Burford et al. named the lung damage caused by chest and abdominal injuries as wet lung (Wet lung); in 1946, Brewer et al. reported increased airway secretion in war-wounded patients and called it Wet lung syndrome; in 1948, Moon described for the first time the occurrence after trauma, burns, sepsis and major surgery of acute respiratory distress. Nonthoracic trauma comp...

AI Technical Summary

Problems solved by technology

[0007] The present invention provides an electrical impedance imaging information acquisition device, which is used to realize timely response or fast feedback of the patient's lung parameters during mechanical ventilation for patients with respiratory distress, so as to reduce the risk of positive end-expiratory pressure during mechanical ventilation. (positive end-expiratory pressure, PEEP) is too high or too low leading to mechanical ventilation-related lung injury
