Effect of air flow and flow transducer on tracheal breath sounds


Tracheal breath sounds (TBSs) were analysed in 12 normal adult subjects at the air flow levels of 1·6, 2·1 and 2·6 litre s−1, using a low-resistance flow transducer, and at an estimated flow of 2·1 litre s−1 without the flow transducer. The major findings were that the TBSs were significantly distorted by the flow transducer, but were independent of air… (More)
