Automated control of end-tidal inhalation anaesthetic concentration using the GE Aisys CarestationTM†
نویسندگان
چکیده
Editor’s key points † New anaesthetic machines can automatically control the concentrations of volatile agents and fresh gas flow. † This study compared the ETControlTM with manual adjustment of fresh gas flow by the anaesthetist in clinical practice. † Time spent at low gas flows was significantly greater and volatile agent usage and costs were lower when using the automated system. † Further studies are needed to confirm these findings. Background. Automated control of end-tidal inhalation anaesthetic concentration is now possible. The EtControlTM module of an Aisys Carestation Anaesthetic machine digitally adjusts fresh gas flow and plenum vaporizer output to achieve a target end-tidal concentration.

Wash-in and wash-out of sevoflurane in a test-lung model: A comparison between Aisys and FLOW-i
Background: Modern anaesthesia workstations are reassuringly tight and are equipped with effective gas monitoring, thus providing good opportunities for low/minimal flow anaesthesia. A prerequisite for effective low flow anaesthesia is the possibility to rapidly increase and decrease gas concentrations in the circle system, thereby controlling the depth of anaesthesia. Methods: We studied the ...

متن کاملDetermination of end-tidal sevoflurane concentration for tracheal intubation in children with the rapid method.
PURPOSE Using the conventional method of determining the end-tidal concentration of inhalational anaesthetic for tracheal intubation, a constant end-tidal anaesthetic concentration is maintained for at least 15 min. As sevoflurane has a low tissue/gas partition coefficient, it seems possible in paediatric patients to determine end-tidal concentrations for tracheal intubation more rapidly by usi...
متن کاملAutomatic end-tidal gas sampling system for non-invasive rCBF measurements.
Non-invasive measurements of regional cerebral blood flow (133Xe inhalation or IV injection) require knowledge of the arterial 133Xe concentrations, which is usually estimated from the end-tidal expiration. An automated sampling system is described for measurement of end-tidal 133Xe concentration that can be used in both spontaneously breathing and mechanically ventilated patients. A comparison...
متن کاملModel-based automatic feedback control versus human control of end-tidal isoflurane concentration using low-flow anaesthesia.
We studied the clinical use of an automatic feedback control system to adjust the end-tidal anaesthetic concentration with a low-flow method. The end-tidal controller uses two input signals (the end-tidal and inspiratory concentrations) to control the isoflurane concentration in the fresh gas flow, using a model-based algorithm. We studied 22 ASA I-III patients during elective surgery lasting m...
