Anesthesia units have additional safety systems that provide a minimum percentage of oxygen (between 21% and 30%) and/or deliver a minimum flow of oxygen (usually 150 to 250 mL/min) (see the Minimum Oxygen Flow and Percentage task). Vaporizers.
WebThe oxygen is piped through a pressure regulator, which maintains a consistent gas pressure in the anesthetic machine (40-55 psi). Flow meter- The oxygen enters the bottom of the fluted (Thorpe) tube, and exits at the top. Read the center of the ball, or top of the float. The flow of oxygen through the tube is controlled by an aperture, WebWhen used at a gas flow of 0.5 liters per minute (LPM), an “H” tank provides up to 230 hours of anesthesia time (an “E” tank gives up to 20 hours at this flow rate). Either size tank must be replaced when the pressure gauge reads 500 PSI or less. OXYGEN FLOWMETER. This device uses an adjustable needle valve to deliver the desired flow ...
