Method And System For Quantifying Timing Discrepancies Between Inspiratory Effort And Ventilatory Assist

摘要

The present disclosure relates to a method and a system for quantifying timing discrepancies between inspiratory effort and ventilatory assist. A trigger error is determined by comparing a start time of neural inspiration with a start time of the ventilatory assist. A cycling-off error is determined by comparing an end time of the neural inspiration with an end time of the ventilatory assist. The ventilatory assist is synchronized when the trigger error is lower than a first threshold and the cycling-off error is lower than a second threshold. The ventilatory assist may also be characterized in terms of early or late trigger and of early or late cycling-off. A trigger of a ventilator may be adjusted according to the trigger error and a cycling-off of a ventilator may be adjusted according to the cycling-off error.

主权项

1. A method of quantifying timing discrepancies between a patient's inspiratory effort and ventilatory assist to the patient, comprising:
determining an early or late trigger error by comparing a start time of neural inspiration with a start time of the ventilatory assist; determining an early or late cycling-off error by comparing an end time of the neural inspiration with an end time of the ventilatory assist; and determining that the ventilatory assist is synchronized when the trigger error is lower than a first threshold and the cycling-off error is lower than a second threshold.
