In looking at the schematics of some of the newest anesthesia machines (e.g., Aisys and Avance, GE Healthcare, Inc., and the former Julian, Dräger Medical, Inc.), I am struck by how they have finally eliminated the hydraulic flow controls (i.e., needle valves) for computer controlled valves. In the developed world, the most frequent type in use is the continuous-flow anaesthetic machine or " Boyle's machine ", which is designed to provide an accurate supply of medical gases mixed with an accurate concentration of anaesthetic vapour, and to deliver this continuously to the patient at a safe pressure and flow. Proportional valves are often located in the middle of the system and provide flow control of the gases employed and prevent over-pressure in lines. The rigid Volume Reflector is never empty to ensure uninterrupted ventilation, and compensates effectively for leakage. 1.6) in which the gas leaves the flow meter from the bottom of the unit. The anaesthetist could vary minute volume by setting tidal volume and ventilatory frequency directly or by adjusting inspiratory time, inspiratory flow rate and the ratio of inspiratory to expiratory time. With a single exception, important safety features can be retrofitted to vintage machines. The anesthesia machine receives medical gases from a gas supply, controls the flow and reduces the pressure of desired gases to a safe level, vaporizes volatile anesthetics into the final gas mixture, and delivers the gases to a breathing circuit that is connected to the patient’s airway. Flow-i provides safe, personalized and cost-efficient care, also for the most challenging patients. This tool makes it simple to set the optimal Fresh Gas Flow (FGF) and minute volume ratio. Proportional valves are considered control elements. Some machines like Drager Fabius GS have conventional control knobs and flow control valves but flow data is displayed electronically using electronic flow sensors and digital displays rather than glass flow tubes.

Even though it is more difficult for theanesthesiologist to achieve a thorough understanding of modern anesthesia machines, it isessential to the safe practice of anesthesia. The anesthesia machine receives gases under pressure from their sources of storage (see Chapter 1), creates a gas mixture of known composition and flow rate, and delivers it to a concentration-calibrated vaporizer, which adds a controlled concentration of potent, inhaled, volatile anesthetic agent. (If this is done, the oxygen flush flow will pass through the vaporizer and may result in gross overdosage when the flush valve is operated.) Oxygen and other medical gases are supplied to the anesthesia machine through a central gas supply or by attaching the cylinder directly to the machine via the hanger yoke. Agent consumption can easily be monitored via the interface. Start using a Flow machine and you’ll quickly notice the attention to detail and thoughtful touches that result from our close collaboration with clinicians. Low-pressure circuit: at second stage reducing device, gas is reduced to 26psi N2O and 14psi for O2.
