The modern medical technology of complex chronomagnetic therapy continues to be improved in several directions, one of which is the development of operational non-contact methods and means for assessing the functional state of a patient during a magnetic therapy session based on an analysis of his breathing process, which allow stable and reliable work under the action of complexly modulated therapeutic electromagnetic fields and large the degree of variability of individual parameters of patients.

The need to solve this problem lies in the fact that today the magnetic therapy doctor has only information about the functional state of the patient, received by him either before the magnetic therapy session or after it, and already with the help of other specialized monitoring tools. This obligatory procedure usually takes a long time for the doctor to make a diagnostic conclusion, takes time from the patient and creates an additional burden for him. The main disadvantage of this procedure is the assessment of the current functional state of the patient in the absence of a therapeutic magnetic field, i.e. when other environmental factors already act on it, and therefore erroneous estimates are possible.

Since the proof of the effectiveness of each session of magnetotherapy is the improvement in the functional state of the patient, i.e. normalization of its vital signs, then prompt objective registration, analysis and measurement of the parameters of the breathing process during magnetic therapy will allow the doctor to timely correct the treatment methodology, optimally plan the treatment strategy and confidently predict the course and outcome of the disease.

The purpose of the work is to confirm the possibility of implementing continuous and non-contact registration of the patient's breathing process and prompt assessment of his functional state during a magnetic therapy session.

To achieve the goal, a physical model of a diagnostic system based on a personal computer, an ultrasonic distance sensor, a multifunctional input-output device and software tools in the form of virtual instruments in the LabVIEW graphical programming environment was developed and created.

Experimental studies and tests of the system were carried out, which confirmed its performance, high level of automation, efficiency in obtaining results, high accuracy in measuring the informative parameters of the breathing process and evaluating diagnostic indicators.

It is planned to introduce the developed method and the system hardware and software into the Multimag and Relaxmag magnetotherapy complexes.
