Abstract:
Objective To study the ventilatory regularity of assist/control-mode ventilation(AMV/CMV or A/C) of Newport E150 ventilator. Methods The mode selector was set to A/C, the ventilatory frequencies(f1) were set at 4,6 breaths per minute(bpm) respectively. The operator inspired to meet the trigger level through the Y piece connected to corrugated hoses within the inspiratory time of CMV in group A, and inspired at the fourth and 60?f1-1second from the beginning of CMV in group B and C respectively. The appearance of AMV and CMV were recorded from the beginning of CMV to the 4+60?f1-1second. The test was repeated 20 times in each group. Results AMV was not triggered and CMV appeared at the 60?f1-1 second in group A. AMV was triggered at the fourth second and CMV appeared at the 4+60?f1-1 second in group B. AMV was triggered at the 60?f1-1 second in group C. Conclusion AMV can be triggered at any time except inspiratory time of CMV. If the ventilator can't trigger the patient's inspiratory effort from the beginning of AMV to the 60?f1-1 second, the mode will switch to CMV automatically.
