Abstract
The present invention provides a system and method for providing a correction to a flow control signal to a flow control valve in a ventilator system. The correction component sums the errors in the flow rate actually delivered as compared with the desired flow rate for each control interval in a breath with the sum of past errors corresponding to control intervals in past breaths to generate a corrected command flow signal to the flow control valve.
