Ventilator with biofeedback monitoring and control for improving patient activity and health
First Claim
1. A ventilator system comprising:
- a ventilator comprising a ventilation gas source, a ventilation gas delivery circuit, and a control unit;
a patient interface in communication with the ventilation gas delivery circuit;
at least one breath sensor;
at least one patient activity sensor;
wherein the ventilator is adapted to be coupled to a patient for permitting ambulation of the patient while performing a portion of work for respiratory muscles of the patient by providing ventilation gas delivery, the ventilator capable of providing the ventilation gas delivery at an instantaneous flow rate of over 30 liters per minute; and
wherein the control unit predicts a chronic obstructive pulmonary disease exacerbation based upon measurements from the at least one breath sensor and the at least one patient activity sensor and adjusts the ventilation gas delivery based upon the prediction to avoid or alleviate the chronic obstructive pulmonary disease exacerbation,wherein the control unit comprises a processor and a memory, and wherein the memory stores measured ventilation parameters regarding activity level of the patient, and wherein after a chronic obstructive pulmonary disease exacerbation, the measured ventilation parameters stored in the memory prior to the chronic obstructive pulmonary disease exacerbation are used to program a signature for predicting future chronic obstructive pulmonary disease exacerbations.

Abstract
A respiratory support ventilator apparatus mechanically supports the work of respiration of a patient. The ventilator apparatus is highly portable and optionally wearable so as to promote mobility and physical activity of the patient, and to improve the overall health of the patient. The respiratory support ventilator may monitor a physical activity level and overall health status of the patient, and process this information. The information is used to track efficacy of the ventilation therapy relative to activity level and quality of life, and or to titrate or optimize the ventilation parameters to improve, maintain or optimize the physical activity level and overall health status of the patient.
