Abstract

The invention relates to a breathing machine pressure stabilizing method based on a back-propagation algorithm. The method comprises the following steps: setting first samples, and judging the numberof the samples; if the number of the samples is smaller, adding a new sample, reading sample parameters of the new sample, adopting the back-propagation algorithm to the sample parameters in the stateto obtain a sample calculation treatment pressure value, judging whether a sample mean square error between a sample treatment pressure and the sample calculation treatment pressure value is smallerthan a critical value; if so, calculating weights of the parameters, storing the same in a storage area, reading actual parameter values in the treatment state, calling the weights of the parameters in the storage area, calculating the calculation treatment pressure in the treatment state, and treating a patient at the treatment pressure of the face mask end; and if the mean square error is greater than the critical value, judging the number of the samples again, and entering the next circulation. By adoption of the breathing machine pressure stabilizing method, fast and accurate compensationof air leakage can be achieved, and the treatment effect and the comfort of the patient are effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of ventilators, and in particular relates to a method for tracking and stabilizing pressure when an air leak occurs during use of a ventilator, in particular a method for stabilizing the leak pressure of a ventilator based on a backpropagation algorithm. Background technique [0002] At present, the sleep apnea machine is the most effective means to treat sleep apnea syndrome. It is easy to use and has obvious therapeutic effects. The main unit passes a breathing tube through the mouth and nose mask to deliver the required treatment pressure to the patient. Obviously, stable and timely and accurate pressure control is an effective guarantee for the efficacy of the sleep apnea machine. [0003] However, during the use of the patient, air leakage may occur to varying degrees in the mask or pipeline. If there is no timely detection and accurate judgment and corresponding control measures are taken, the pressure will drop...
