Ventilator management systems are provided. In one aspect, a ventilator management system includes a memory that includes an initial configuration profile configured to designate operating parameters for a ventilation device, and a processor. The processor is configured to receive ventilator data from the ventilation device, the ventilator data includes at least one of operating parameters of the ventilation device or physiological statistics of a patient associated with the ventilation device, and determine, based on the ventilator data, a modification to the initial configuration profile for the ventilation device.
