1. A ventilation system, comprising:
- a processor communicably coupled to a computer readable medium, wherein the computer readable medium includes instructions for delivering a mandatory breath type, the processor configured to;
calculate patient effort for a first breath of a patient;
based on the calculated patient effort, derive a beginning and an end of the patient'"'"'s inspiratory cycle for the first breath;
calculate a neural inspiratory time based on at least the derived beginning and end of the patient'"'"'s inspiratory cycle for the first breath; and
set the neural inspiratory time as an inspiratory time setting for a second breath, the second breath being of the mandatory breath type.

Abstract
Various embodiments of the present disclosure provide systems, methods and devices for respiratory support. As one example, a ventilation system is disclosed that includes a computer readable medium including instructions for operating in a hybrid mode. These instructions include measuring patient effort during a spontaneous breath type and deriving a neural inspiratory time from the measurements of patient effort. This neural inspiratory time is then set as the inspiratory for a breath of a mandatory breath type. If new patient effort measurements are received by the ventilator, the neural inspiratory time may be adjusted.
