METHOD AND DEVICE FOR COLLABORATING VENTILATION USING EXTERNAL DIAPHRAGM PACEMAKER AND VENTILATOR

摘要

The present invention discloses a method for synchronized ventilation using an external diaphragm pacemaker and a ventilator, which includes the following steps: (1) filtrating captured EAdi signal to reduce the noises, (2) assessing the absolute peak value a of the EAdi signal and: if a<0.5 μV, adjust the external diaphragm pacemaker to issue a stimulus current at a frequency of 10-12 beats per minute, and at the same time trigger the ventilator to perform ventilation in an assisted ventilation mode; if 0.5≦a≦1.0 μV, adjust the external diaphragm pacemaker to issue a stimulus current at a frequency of 5-8 beats per minute, and at the same time trigger the ventilator to perform ventilation in an assisted ventilation mode; if 1.0

1. A method of collaborating between external diaphragm pacemaking and mechanical ventilation comprising the following steps:
(1) filtrating captured EAdi signal mixed with interfering noises to obtain a treated EAdi signal; (2) evaluating an absolute peak value of the waveform of said treated EAdi signal and issuing a control action accordingly: (2.1) if a<0.5 μV, instructing the external diaphragm pacemaker to issue a stimulus current at a frequency of 10-12 beats per minute, and at the same time trigger the ventilator to perform ventilation in an assisted ventilation mode; (2.2) if 0.5≦a≦1.0 μV, instructing the external diaphragm pacemaker to issue a stimulus current at a frequency of 5-8 beats per minute, and at the same time trigger the ventilator to perform ventilation in an assisted ventilation mode; (2.3) if 1.0
