Abstract

Systems and methods may include a gas source, a gas delivery circuit, and a nasal interface allowing breathing ambient air through the nasal interface. A gas flow path through the nasal interface may have a distal gas flow path opening. A nozzle may be associated with a proximal end of the nasal interface a distance from the distal end gas flow path opening. At least a portion of an entrainment port may be between the nozzle and the distal end gas flow opening. The nozzle may deliver gas into the nasal interface to create a negative pressure area in the gas flow path at the entrainment port. The nasal interface and the nozzle may create a positive pressure area between the entrainment port and the distal end gas flow path opening. Gas from the gas delivery source and air entrained through the entrainment port may increase airway pressure or lung pressure or provide ventilatory support.

Abstract

A method for detecting sleep for continuous positive airway pressure (CPAP) therapy is disclosed. Discrete values of a control signal generated by a pressure controller to regulate delivered pressure at the patient are measured over a predefined time window encompassing one or more respiratory cycles. A baseline control signal value is generated from a weighted average of the measured discrete values of the control signal. Estimates of a respiratory cycle period, an inspiration control time, and an expiration control time are then generated. Estimates of one or more secondary control signal properties for each of the respective inspiration control time and expiration control time are generated. Pressure to the patient is increased in response to an evaluation of the estimates of the one or more secondary control signal properties being indicative of the patient reaching a sleep state.

Abstract

Methods for detecting a patient disconnecting from a continuous positive airway pressure (CPAP) therapy device are disclosed. A cyclical pressure difference signal is derived based upon measurements from a patient interface pressure sensor and from a source pressure sensor. The pressure difference signal is integrated to generate a resultant integral signal for each respiratory cycle, which is comprised of at least one inspiratory phase and at least one expiratory phase as represented by the corresponding portions of the pressure difference signal. A pressure source of the CPAP therapy device is deactivated in response to a disconnect condition being evaluated from the integral signal. In one embodiment, the disconnect condition is the integral signal exceeding a predefined disconnect threshold. In other, it is a slope value corresponding to a rate of increase of the integral signal exceeding a predefined threshold for a predefined duration.

Abstract

Indicating fit status of a mask in communication with a respiratory assistance device is disclosed. Upon initiating a therapeutic gas delivery from the respiratory assistance device to the mask, one or more measurements from respective one or more sensors of the respiratory assistance device is received. A leakage value from these measurements is derived, and a mask fit index is assigned. This is based at least upon a correlation of the leakage value to a particular sub-range of predetermined leakage values that corresponds to the mask fit index. The particular sub-range of predetermined leakage values is one among a plurality of sub-ranges, which together comprises an overall mask fit range defined at least by an ideal mask fit region, a loose mask fit region, and a tight mask fit region. A mask fit status based upon the assigned mask fit index is output to an indicator interface.

Abstract

A portable liquid oxygen system may provide an average flow rate of oxygen gas at approximately 6-approximately 20 lpm using a rapid gas conversion mode. The rapid gas conversion mode utilizes a Stirling engine that harnesses the heat differential between the ambient temperature and the liquid oxygen store to drive a fan. The fan operates to blow ambient air across a heat exchanger, which allows the heat exchanger to more rapidly evaporate liquid oxygen into oxygen gas.
