| 142 | METHOD AND SYSTEM FOR CHECKING THE OPERABILITY OF A BREATHING EQUIPMENT | EP97905529 | 1997-02-18 | EP0886537A1 | 1998-12-30 | LUNDBERG MATS |
| A system checks the operability of electrical-based components (10, 14, 17, 19) in a breathing equipment (16), such as a Self-Contained Breathing Apparatus (SCAB), for example. The system includes a microprocessor (7) which is communicatively coupled with the electrical-based components (10, 14, 17, 19). After a power-up of the breathing equipment, the microprocessor (7) receives a signal from the electrical-based components (10, 14, 17, 19) indicating the operational state of that particular component. If the signal is not received by the microprocessor (7), or the signal deviates from a predetermined threshold, then that electrical-based component (10, 14, 17, 19) has failed to function properly. In that case, a visual indication of the failure is provided to a user of the breathing equipment (16). In addition, the system provides a visual identification of whether the microprocessor (7) itself is malfunctioning. A method is also provided for checking the operability of electrical-based components (10, 14, 17, 19) in the breathing equipment (16). | ||||||

| Apparatus and associated methods relate to determining a fit-quality metric for a mask/face combination based upon a calculated dead-space volume between a virtual mask and a virtual face virtually aligned so as to create an integrity seal circumscribing a mouth and nose region. In an illustrative embodiment, an interactive virtual fitting system may receive a three-dimensional (3D) virtual face associated with a person. The system may retrieve 3D models of various respirators selected by user determined criteria. The system may then compute a fit-quality metric for each of the retrieved 3D models. The potential wearer may then be presented with the metrics for review. The potential wearer may select a respirator based upon these computed metrics. A virtual fitting of many respirators may advantageously reduce the time needed for selecting a properly fitting respirator while simultaneously ensuring that the selected respirator may be comfortable and well fitting. | ||||||

| 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. | ||||||
