From: Inspiratory response and side-effects to rapid bilateral magnetic phrenic nerve stimulation using differently shaped coils: implications for stimulation-assisted mechanical ventilation

Fig. 4

Inspiratory and side-effect responses to rapid bilateral anterior magnetic phrenic nerve stimulation (RMSBAMPS) with different stimulator-output and stimulation-frequency combinations. A Number of subjects that showed an inspiratory response to RMSBAMPS that reached each tested stimulation setting; one participant did not undergo RMSBAMPS with the butterfly coil. B Tidal volume in response to RMSBAMPS (N = panel A). C Number of subjects who were equipped with balloon catheters that showed an inspiratory response to RMSBAMPS and reached each tested stimulation setting. D Mean transdiaphragmatic pressure responses to RMSBAMPS (N = panel C). E–G Pain, discomfort and paresthesia in response to RMSBAMPS (N = panel A). H Change in galvanic skin response in response to RMSBAMPS (N at 20% = 10 due to technical difficulties). *, main effect of stimulator-output; †, main effect of stimulation-frequency; ‡, interaction effect (P < 0.05). Values in panels A and C are absolute count, while all other values are mean + SD
