Abstract: The present technology is directed to ventilator systems that can provide both ventilation therapy and oxygen therapy. The systems described herein may include a ventilation assembly that can provide inspiratory gas to a patient circuit and an oxygen assembly that can provide pulses of oxygen to an oxygen delivery circuit. In some embodiments, the oxygen delivery circuit is distinct from the patient circuit. For example, the patient circuit can include a corrugated conduit coupled a ventilation mask, and the oxygen delivery circuit can include a nasal cannula. The ventilation mask can be positioned over the nasal cannula so that the patient can receive both the inspiratory gases and the pulses of oxygen.

Abstract: The present technology is directed to respiratory therapy data management systems, device, and methods. The systems can collect, store, monitor, report, and/or analyze patient treatment data associated with patient use of one or more respiratory therapy devices. The patient treatment data can include therapy data related to the use of multiple respiratory therapies, such as ventilation, oxygen, cough-assistance, suction, and nebulization. The patient treatment data may be collected from a plurality of respiratory devices associated with a particular patient, or from a single respiratory device associated with a particular patient. The system can generate customizable reports detailing the patient treatment data. The reports can summarize patient use, illustrate therapy trends, and/or provide therapy recommendations.

Abstract: A ventilator device and system comprising a rotating compressor, preferably a drag compressor, which, at the beginning of each inspiratory ventilation phase, is accelerated to a sufficient speed to deliver the desired inspiratory gas flow, and is subsequently stopped or decelerated to a basal flow level to permit the expiratory ventilation phase to occur. The ventilator device is small and light weight enough to be utilized in portable applications. The ventilator device is power efficient enough to operate for extended periods of time on internal or external batteries. Also provided is an oxygen blending apparatus which utilizes solenoid valves having specific orifice sizes for blending desired amounts of oxygen into the inspiratory gas flow. Also provided is an exhalation valve having an exhalation flow transducer which incorporates a radio frequency data base to provide an attendant controller with specific calibration information for the exhalation flow transducer.

Abstract: A portable mechanical ventilator uses a constant-speed compressor compressor and a recirculating bypass circuit. Bypass flow is governed by a spring-biased bypass valve so connected to both the inlet and the outlet of the main flow control valve as to maintain a differential pressure across the flow valve sufficient to operate the ventilator with minimal energy consumption. The flow valve is operated by a microprocessor in accordance with empirically derived lookup tables to both produce the desired air flow and provide a measure of that air flow.
