The model that signal characteristic is set up, or model, then the signal that subsequently will be gathered every time are set up according to the signal characteristic of multi collect
Feature carries out sophisticated model in continuously adding the model, for example, the patient that is critically ill, shock patients, hypothyroidism and mostly
In number exhaustion at heart, Addison's disease, the recovery process and artery chronic hardening heart disease of serious heating, and part
In valve lesion and hyperpietic, low dynamics ballistocardiography waveform can be shown.Most thyroid functions permit into, extremely disappear
In the normal subjects of thin person, part anaemia, arteriovenous aneurysm, heating, early high blood pressure and only a few, powered arbor high is shown
Impact figure waveform.Furthermore, around in vascular diseases, such as pulseless disease, peripheral arteriosclerosis, thromboangiitis etc., normal table
Reveal abnormal ballistocardiography waveform, including I ripples it is narrow and shallow or disappear, K ripples increase deep, K ripples or J ripple incisuras etc..
In diabetic, unusual waveforms are also shown, the abnormal ballistocardiography change, including amplitude attenuating, diastole
Phase amplitude increases, morning M shapes, late concave shape and waveform is poor etc. during breathing.These show as many companions of patient of abnormal ballistocardiography
There is cholesterin rising disease shape.Larger surgical site infections, I-J wave-amplitudes are substantially reduced, and the phenomenon is suitably infused to subject
After have clear improvement, this be probably when some are performed the operation cardiac output reduction caused by.
So, for different types of disease, the waveform of ballistocardiography signal has corresponding change, can be by setting up
After these can react the model of health, the ballistocardiography signal after the treatment that Cloud Server 310 will can be obtained
Compare with the model with signal characteristic is extracted in channels and collaterals signals, its data processing speed is fast, can quickly draw user
Vital sign testing result, i.e., user whether in illness, heart rate is too fast or under other unsafe conditions, is not suitable for
Take vigorous exercise.
