Abstract:
Objective To learn the influence of PALL BB25S and Tyco Hygroboy breathing filter (BF) to Ppeak and Pmean. Methods The changes of Ppeak and Pmean were detected by using PALL BB25S and tyco Hygroboy in simulation ventila- tion. Results (1)When BFs (PALL or tyco, adult or child) were applied and Vt from 100ml/T to 800ml/T, the effect of breathing filter can be no significant changed, but Pmean was raised and Ppeak no change. (2)To compare the tyco BFs, the Pmean of child BF and adult BF, Pmean was significant increased. Conclusion Both of PALL BF and Tyco BF only significantly increase Pmean.
