Method and device for collaborating ventilation using external diaphragm pacemaker and ventilator
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<a≤2.0 μV, adjust the external diaphragm pacemaker to issue a stimulus current at a frequency of 3-4 beats per minute and at the same time trigger the ventilator to perform ventilation in an assisted ventilation mode. The present invention also discloses a device which couples an external diaphragm pacemaker to a ventilator. The present invention brings the external diaphragm pacemaker into the application of mechanical ventilation in the emergency room and intensive care unit.
