A breathing gases supply apparatuscan comprise a blowerand breathing circuit for delivering breathing gases to a patient. The apparatus also can comprise a first controller, the controllerconfigured to receive input from at least one sensor-indicative of patient breathing, and a transmitterconfigured to communicate with the controllerand transmit control signals to an electronic apparatus. The controllercan be configured to determine sleep in a patient based on the occurrence of a breathing pattern indicative of sleep, detected from the input received from the sensor-and upon determining sleep, operate the transmitterto send a control signal to control an electronic apparatus

Electronic apparatus control using a breathing assistance apparatus

A positive airway pressure apparatus is automatically adjusting. Pressure increases in response to apnea events when the apparatus is in one or more responsive states. Pressure does not increase in response to apnea events when the apparatus is in a non-responsive state. The apparatus switches between responsive and nonresponsive states depending upon any of a number of different criteria that help differentiate between open airway apnea events and closed airway apnea events.

Pressure adjustment method for CPAP machine

An apparatus and method of controlling the delivery of therapeutic gas delivered to a patient undergoing positive airway pressure therapy is described. The method includes providing a flow of gas to a patient's airway at a pressure, obtaining information from the range of 0 to 25 Hz of the frequency domain of the flow, and adjusting the pressure based on the information. The apparatus includes a blower for providing a flow of gas to a patient's airway at a pressure, a sensor to measure a characteristic of the flow, a controller to obtain information from the range of 0 to 25 Hz of the frequency domain of the characteristic, and a pressure regulator for adjusting the pressure based on the information.

Autotitrating method and apparatus

A fan unit which in use forms part of a gases supply unit, the gases supply unit suitable for use as part of a system for providing heated humidified gases to a user, the fan unit having a casing that has an inlet aperture and an outlet passage, the outlet passage including an exit aperture, the fan unit also including a fan which is located inside the casing and which is adapted for connection to a motor to drive rotation of the fan in use, the fan drawing gases into the casing via the inlet aperture, and forcing these gases out of the casing via the outlet passage as a gases stream, the outlet passage further including at least one bypass vent hole independent of the exit aperture and arranged at an angle to the path of the gases stream through the outlet passage.

Nasal pillows with high volume bypass flow and method of using same

A CPAP system for supplying humidified gases to a user is disclosed in which various interfaces are described for gas delivery. A mask cushion including a deformable cushion and thin sheath is described.
