Passive expiration as a test of lung function.
Twenty-five normal subjects, 14 non-smokers and 11 smokers, passively expired into a spirometer after a maximal active inspiration, and after a passive inflation of the chest by a pressure cycled intermittent positive-pressure breathing (IPPB) machine. Acceptable passive expirations could be performed by all subjects after a passive inspiration but by only 12 after an active inspiration. Expire...
متن کاملKnot integrity as a function of suture expiration.
OBJECTIVE To test the integrity of knots tied with expired suture and non-expired suture, using 5 different suture materials. STUDY DESIGN Knots were tied using expired and non-expired chromic catgut, polyglactin 910, polydioxanone, silk, or coated polyester. Expired sutures were a mean of 10.5 years past the date of expiration stamped on the packaging. Suture packaging was inspected for any ...
متن کاملForced expiratory time--its reliability as a lung function test.
Three studies of factors affecting variability of forced expiratory time (FET) have been carried out. In the first, different observers or repeated measurements over a few minutes were shown to make no significant contribution to FET variability. Time of day was also relatively unimportant. In the second study, FET was shown to vary considerably more than peak flow rate, forced expiratory volum...
متن کاملMechanical compliance and resistance of the lung-thorax calculated from the flow recorded during passive expiration.
C OMROE, Nisell and Nims (I) have suggested that measurements upon purely passive expiration curves may be used as a rapid method for demonstrating changes in the mechanical properties of the lungs and thorax of animals and man. Essentially, their technique consists of inflating the lungs of animals or man (made apneic by deep anesthesia, curarization, or hyperventilation) to a known alveolar p...
متن کاملconstructing a test to predict the translation performance of english translation ma graduates on legal correspondence and deeds as a profession
