Method and apparatus for the control of the breathing with detection of the influence of the lbs cardio vascular -

摘要

For studying the respiratory activity by means of the signals 5 of the variation of the electrical impedance of the thorax, it causes, without being hindered by the variations of this same impedance as a result of the beats of the cîoeur, it receives the cardiac signals 15, the delays in 20 in order to compensate for the delay of the muscles, and they are compared with a third signal 25 representing the negative slope of 5. When this third signal starts a predetermined time after 15, the discriminator 50 sends a pulse to a counter 60, which generates a signal unpacking each time that it has recorded a determined number of successive pulses. It then allowed to pass the signal 5 towards the outlet 90. & br / (see appended drawing in bopi) & br / & & br /
