Lung recruitment maneuver ventilation control method and device

Abstract

The embodiment of the invention discloses a lung recruitment maneuver ventilation control method used for setting in an anaesthesia machine so as to monitor the lung recruitment maneuver process. The method comprises the following steps that lung recruitment maneuver ventilation parameters are set through a human-computer interface; lung recruitment maneuver ventilation operation is performed according to the set lung recruitment maneuver ventilation parameters; when an abnormity occurs in the lung recruitment maneuver ventilation operation process, a quit key is clicked to quit the lung recruitment maneuver function, and the ventilation mode adopted before lung recruitment maneuver ventilation is performed is restored. The embodiment of the invention correspondingly discloses a lung recruitment maneuver ventilation control device. The lung recruitment maneuver ventilation control method and device have the advantages that operation is simple, and the ventilation operation state adopted before lung recruitment maneuver can be easily and quickly restored.

Description

technical field [0001] The invention relates to the technical field of lung recruitment in medical equipment, in particular to a lung recruitment ventilation control method and device. Background technique [0002] Alveoli are the sites of gas exchange, and there are 300 to 400 million alveoli in adults, providing enough area for gas exchange. There are two types of alveolar epithelial cells, one is responsible for the diffusion of gas; the other can form a layer of liquid film on the surface of the alveoli to reduce the surface tension of the alveoli and keep the alveoli inflated without collapsing at the end of expiration. [0003] Data show that the incidence of atelectasis in patients induced by anesthesia is over 90%. During and after anesthesia, due to the application of various analgesics and sedatives to inhibit the expectoration function of the respiratory tract, thick secretions cannot be coughed up, which can block the small bronchi. If the lungs are not fully i...

Problems solved by technology

[0019] First of all, all stages of the lung recruitment process are realized by the doctor manually adjusting the ventilation mode setting parameters. After the recruitment is completed, the ventilation parameters need to be reset, which is inconvenient to operate;

[0020] Secondly, if the state is abnormal during the lung recruitment process, it cannot be quickly restored to the previous state before the recruitment at any time, because the ventilation parameters have been modified, or even modified multiple times, it is difficult for the doctor to set the parameters of the ventilation mode in a hurry.
