Anaesthesia Breathing Systems
Anaesthesia Breathing System (formerly known as anaesthesia Breathing Apparatus or Anaesthesia Breathing Circuit) is an interface between the anaesthetic machine and the patient. They evolved over 160 years from the open systems used by Morton to the present day closed systems using carbon dioxide absorbents. The main purpose of these systems is to deliver the required oxygen and anaesthetic ga...
متن کاملevaluation of bacterial contamination in anesthesia breathing circuits
introduction : hospital infections are one of the important reasons of mortality and incurred expenses. therefore, we must control these infections by identifying contamination sources. the aim of this study was the determination of bacterial pollution of corrugated anesthesia sets in surgical rooms. methods: this study was an analytic-description one performed in training hospitals of yazd cit...
متن کاملQuantal ventilatory variability during spontaneous breathing anaesthesia.
BACKGROUND Cardioventilatory coupling is the triggering of inspiratory onset by preceding cardiac activity. We have observed two forms of coupling with a bimodal ('quantal') variation of respiratory period. METHODS We investigated the variables of inspiratory duration (TI), expiratory duration (TE), and tidal volume (VT) where respiratory period variation was bimodal. In 25 anaesthetized spon...
متن کاملSevoflurane degradation to compound A in anaesthesia breathing systems.
Determination of an effective rate constant and activation energy allowed the application of steady-state theory to predict concentrations of compound A from sevoflurane concentrations, fresh gas flow rate, absorbent temperature and amount of absorbent. Studies by eight research groups were compared. Lower concentrations of compound A than predicted were observed at low flow rates, suggesting t...
متن کاملNaloxone does not influence breathing during isoflurane anaesthesia.
Naloxone influences ventilation, probably by an action on endogenous opioids, in several conditions in which ventilation is reduced or impaired. Ventilatory depression is a feature of anaesthesia; some of the actions of anaesthetic drugs have been attributed to endogenous opioids. Naloxone was given to two groups of patients to investigate the possibility that ventilatory depression might be re...
