“…Therefore, we implemented the same experiment as that performed in an older study (10 y ago) 2 using the same parameters for the static portion; used the same dynamic experiments as used in many previous bench studies. [3][4][5][6][7][8] In addition, we showed that the most recent turbine transport ventilators are a breakthrough in the field of transport ventilators even if they have some limitations, and their performances are close to those of ICU ventilators.…”

“…Most of the studies reporting ventilator performance 3,4 use some version of the Training and Test Lung (TTL) simulator (Michigan Instruments, Grand Rapids, Michigan).

Prispelo: 14. 9. sprejeto: 5. 3. 2017 Funkcije anestezijskega dihalnega balona v dihalnem sistemuFunctions of anesthesia reservoir bag in a breathing system Miljenko križmarić IzvlečekV članku predstavljamo različne funkcije anestezijskega dihalnega balona v dihalnem sistemu. Osrednji namen prispevka je razložiti dokaj zapleteno interakcijo med dihalnim balonom in dotokom svežih plinov med mehaničnim predihavanjem. Anestezijski dihalni balon je podajni zbiralnik plinov in predstavlja ključno komponento v večini dihalnih sistemov. Balon omogoča ročno predihavanje in je vizualni ter taktilni monitor spontanega dihanja. Balon je pri uporabi mehaničnega predihavanja izključen iz tradicionalnega dihalnega sistema. V takem primeru opazimo neujemanje med nastavljeno in dejansko vrednostjo enkratnega volumna. Na nekaterih anestezijskih delovnih postajah, kot je Dräger Primus, pa balon med mehaničnim predihavanjem služi kot zbiralnik dihalnih anestezijskih plinov in sodi v sestavni del dihalnega sistema. Med mehaničnim predihavanjem plini pri vdihu zaradi zaprte zaklopke razdruževanja svežih plinov tečejo iz dovoda svežih plinov v balon. Varna splošna anestezija zahteva razumevanje tehnoloških novosti v zapletenih napravah, ki jih pri tem uporabljamo. AbstractThis article addresses the different functions of anesthesia reservoir bag in a breathing system. A main purpose of the contribution was to explain complex interaction between the reservoir bag and fresh gas flow during mechanical ventilation. The anesthesia reservoir bag is a collapsible gas container which is an essential component of most breathing systems. The anesthesia reservoir bag permits manual ventilation and acts as a visual or tactile indicator of spontaneous ventilation. The bag was excluded from traditional breathing system when the ventilator was in use. Discrepancies between the set and actual tidal volume can occur. However, on some anesthesia workstation systems, such as the Dräger Primus, the reservoir bag is an integral part of the breathing system during mechanical ventilation, where it serves as a reservoir for oxygen and anaesthetic gases. In mechanically ventilated patients, gases enter the bag from the fresh gas flow during inspiration, when the decoupling valve closes. The safe administration of general anesthesia requires understanding of the technological advances in highly sophisticated anesthetic equipment.

Delivery of tidal volume from four anaesthesia ventilators during volume-controlled ventilation: a bench study

Abstract: Under experimental conditions, the volume error differed significantly between the four new anaesthesia ventilators tested and was influenced by FGF, although this effect may not be clinically relevant.
