Problems solved by technology

[0004] One of the purposes of the present invention is to propose a ventilation mode switching method for anesthesia machines with respiratory support, which solves the problem of using default parameter settings for switching between different modes of traditional anesthesia machines in the prior art, which requires cumbersome operating parameter settings, and Inconsistent parameter settings in different modes lead to different tidal volume values, which will cause damage to the lungs

Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] In the embodiment of the present invention, aiming at the idea of ​​passively and actively accepting ventilation, a new mode switching scheme is proposed, and an implementation method of controlling ventilation mode switching to SIMV mode is introduced in detail. figure 1 is a schematic diagram of the main flow of the ventilation mode switching method according to an embodiment of the present invention, such as figure 1 As shown, the method mainly includes the following steps:

[0024] Step S101: Obtain the tidal volume value in SIMV mode;

[0025] Step S103: adjust the breath-hold time and inhalation time according to the tidal volume value, the respiratory rate value and the inspirat...

Abstract

The invention provides a ventilation mode switching method and device for a breath-supported anesthesia apparatus. The invention solves the problems that the traditional anesthesia apparatus adopting default parameter settings when switching among different modes in the prior art needs complicated operation parameter settings, and inconsistency of parameter settings of different modes can lead to different tidal volumes, causing harm to the lungs. The method can switch the ventilation mode from a control ventilation mode to a synchronous intermittent command ventilation (SIMV) mode, and comprises the following steps: S101: acquiring the tidal volume in the SIMV mode; S103: adjusting the breath holding time and inspiration time according to the tidal volume, breathing rate and inspiration / expiration ratio; and S105: adjusting the breathing rate. Compared with the prior art, the invention is more suitable for breath management, enhances the operation safety of the anesthesia apparatus or breathing machine, lowers the harm to the lungs, and is convenient for operation.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a ventilation mode switching method and device. Background technique [0002] The anesthesia machine not only has the function of providing the correctness of anesthesia, but also the function of breathing support and detecting the operation status. The latter two functions are designed based on the principle of human inhalation and exhalation. When is passive breathing and when is it? Active breathing is very important in surgery, and the breathing mode is switched according to different situations, but this switching is unstable and may cause damage to the lungs. Controlled ventilation is a process of passively receiving ventilation. Common passive control modes include Intermittent Positive Pressure Ventilation (IPPV: Intermittent Positive Pressure Ventilation), Constant Pressure Controlled Ventilation (PCV: Pressure Controlled Ventilation), etc. Synchronized ventilation is a pr...
