| A low-profile filter frame is disclosed for maintaining an open filter plenum configuration during normal operation, and for enabling quick and reliable negative pressure testing. The frame has upper and lower halves. A breathing tube in the lower half connects to a respirator port. The upper and lower halves snap together to maintain the structure in an assembled configuration. The halves also include features that bias the halves apart when the device is in the assembled configuration, thereby maintaining the breathing tube open. To perform a fit test, a force is applied to an outer surface of the upper half, which moves the halves together, in opposition to the bias, so that the upper half seals against the breathing tube. The frame can be provide in as a single-piece, with a living hinge connecting upper and lower halves, or the upper and lower halves can be separate pieces. | ||||||

| 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. The microcontroller (38) continuously determines mask leak as the value, fLEAK, from a flow sensor (32), comparing this to a threshold, and providing the patient with a visual indication of degree of leak. In this way the patient can manipulate the mask to ensure correct fitting as indicated by the appropriate message or indication. | ||||||
