Funkcije anestezijskega dihalnega balona v dihalnem sistemu

Tis 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.
