| The respiratory booster machine is configured to generate and transmit particularly designed and timely delivered vibrations to the lungs of a subject to improve ventilation, augment diffusion of gases across alveolar membrane, facilitate pulmonary blood perfusion, prevent focal alveolar collapse, and enhance effective expectoration. The machine has an acoustic signal generator having modulated wave-generating circuitry and an acoustic signal transmitter having an electro-acoustic transducer. Vibrations from the acoustic signal are induced into the subject's air stream, in one embodiment by a specially designed tube system, and then transmitted to a subject's airways via any type of endotracheal tube, respiratory mask, nasal prong, or directly through the chest wall. Acoustic signal receivers connected to a computer receive and analyze the effect of the vibrations on the subject. The machine can be used independently or in combination and cooperatively with any type of ventilator machine, either conventional or high frequency. | ||||||

| A system and method for the remote administration of respirator fit tests are disclosed, along with a system and method for administering qualitative respirator fit tests to two or more test subjects simultaneously. Remote administration of respirator fit tests involves the testing of test subjects located at one facility by a test administrator located at a different facility. The two facilities may be located, for example, in the same city, in different countries, etc. As a result, a single test administrator may, for example, be able to administrate fit tests with test subjects located in a variety of facilities in one day without traveling. Qualitative respirator fit testing systems and methods of the invention include multiple test stations and an aerosol generator system in fluid communication with each of the test stations. The aerosol generator system may be capable of delivering aerosol to the test stations in repeatable, selected amounts and may also be capable of delivering the aerosols to some or all of the stations simultaneously. | ||||||

| 87 | Combined aircrew systems tester (cast) | US10522721 | 2003-07-17 | US20050145245A1 | 2005-07-07 | Clifford Jordan |
| The present invention enables functional testing nearly all aircrew equipment including a COMBAT EDGE (combined advance technology enhanced design “G” ensemble) system of components which include a mask, a G-suit, communication systems, and a goggle. The present invention includes a gas system which includes an input filter (101), a first compressor (102) comprising at least one blower, preferably three blowers connected in series, a second compressor (103), a first flow sensor (106), a second flow sensor (107), a first flow valve (104), a second flow valve (105), a regulator (108), a first pressure sensor (112), a second pressure sensor (113), a first pressure valve (110), a second pressure valve (114), and a controller. The inlet filter (101) is designed to accept a chemical filter. The second compressor (103) produces a lower flow at a higher pressure than the first compressor (102). This combination works particularly well when inflating the G-suit because when the G-suit inflates, initially there is a large change in volume without much change in pressure, and then, as the G-suit fills out and becomes firm, the chance in volume slows down and the rate of the pressure increases. The present invention includes a digital indicator. A method of operating the tester and the gas system are also disclosed. The present invention includes a normal breathing test, a preflight test, a G-suit leak test and two dynamic flow leak tests. The communication system test and goggle test are further included. | ||||||

| 90 | Determination of mask fitting pressure and correct mask fit | US09469954 | 1999-12-21 | US06425395B1 | 2002-07-30 | Gregory Newton Brewer; Gregory Alan Colla; Steven Paul Farrugia; Chinmayee Somaiya |
| 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. The microcontroller continuously determines mask leak as the value, fLEAK, from a flow sensor, comparing this to a threshold, and providing the patent 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. | ||||||
