Weaning method and weaning device for intelligent breathing machine

Abstract

The invention discloses an intelligent breathing machine and a weaning method for the intelligent breathing machine. A ventilation effect can be automatically realized by the intelligent breathing machine before weaning is carried out. The weaning method includes examining variation delta V of the volumes of the pulmonary alveoli of a patient, variation delta P of the internal pressure of the pleural cavity of the patient and the spontaneous breathing frequency f of the patient at first; computing work W of breathing and a rapid-shallow-breathing index RSBI of the patient by the aid of examined values; monitoring a numerical value of the blood oxygen saturation degree SpO2 of the patient and a numerical value of end-tidal carbon dioxide EtCO2 of the patient; comparing computed values and the monitored values to weaning standards of the breathing machine; implementing weaning if the weaning standards of the breathing machine are met; implementing secondary weaning judgment if the weaning standards of the breathing machine are not met. The intelligent breathing machine, the weaning method and a weaning device have the advantages that various key indexes of vital signs of the patient are monitored automatically, so that whether weaning is implemented or not can be comprehensively judged, and the weaning judgment accuracy can be improved; a good clinical effect can be realized by the weaning method, and the weaning method and the weaning device bring convenience for medical staff to accurately implement weaning operation according to weaning information.

Description

technical field [0001] The invention relates to the field of ventilators, in particular to an intelligent ventilator weaning method and a weaning device. Background technique [0002] Ventilator is a device that can replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce breathing work consumption, and save heart reserve capacity. [0003] As a life support method, the ventilator can assist patients with primary diseases to breathe. Usually, patients who use the ventilator for too long or other factors will have a relatively strong dependence on the ventilator, such as: the use of the ventilator for more than two weeks, resulting in repeated weaning failures, prolonged hospitalization, and increased ventilator-associated pneumonia ( VAP), ventilator-related lung injury (VILI) and other complications. Therefore, once the primary disease improves or the predisposing factors improve, it is necessary t...
