Abstract: CPAP treatment apparatus (10), as one form of positive pressure ventilatory assistance, is disclosed. A turbine/blower (14), operated by a mechanically coupled electrical motor (16), receives air or breathable gas at an inlet (18) thereof, and supplies the breathable gas at a delivery pressure to a delivery tube/hose (20) having connection at the other end thereof with a nose mask (12). A microcontroller (38) has an operational “Mask-Fit” mode. An initial constant pressure level is applied by the blower (14) to the mask (12). If the functional mode is a Manual mode, then the mask-fit test pressure is the current ‘set’ pressure. If the functional mode is the Automatic Titration mode, the mask-fit test pressure is the 95th percentile pressure of the previous session, otherwise it is the base treatment pressure, e.g. 10-12 cm H2O. This constant pressure is applied for a period of time, typically 1-3 minutes.

Abstract: Methods and apparatus for detection and treatment of respiratory disorders using implanted devices are described. In one form, afferent nerves are electrically or electro-mechanically stimulated to increase the tone of upper airway muscles. Detection of respiratory disorders is carried out using electrodes implanted in sub-pectoral regions. Open and closed airway apneas are distinguished using a combination of acoustic detectors and electrical transducers.

Abstract: A method for determining a mask-fit test pressure to be applied to a wearer's mask by ventilatory assistance apparatus includes adaptively determining the mask-fit pressure from prior use.

Abstract: A CPAP treatment apparatus, as one form of positive pressure ventilatory assistance, includes a turbine/blower, operated by a mechanically coupled electrical motor that receives air or breathable gas at an inlet thereof, and supplies the breathable gas at a delivery pressure to a delivery tube/hose having a connection at the other end thereof with a nose mask. A microcontroller has an operational “Mask-Fit” mode. An initial constant pressure level is applied by the blower to the mask. If the functional mode is a manual mode, then the mask-fit test pressure is the current ‘set’ pressure. If the functional mode is the automatic titration mode, the mask-fit test pressure is the 95th percentile pressure of the previous session, otherwise it is the base treatment pressure, e.g. 10-12 cm H2O. This constant pressure is applied for a period of time, typically 1-3 minutes.
