Flowmeter<br />

<strong>The</strong> anesthetic flowmeter is a component of the anesthetic delivery unit (anesthetic machine)<br />

that simultaneously controls and displays the rate of delivery of a given medical gas. Flowmeters<br />

are used for the delivery of air, oxygen and nitrous oxide. (Volatile anesthetic gases<br />

are delivered via a vapourizer, not a flowmeter.)<br />

<strong>The</strong> flowmeter allows delivery of one or two (but not three) gases at once.<br />

Many different designs of flowmeters have been used over the years. <strong>The</strong>re are numerous<br />

sophisticated safety features built into the design of the modern anesthetic flowmeter.<br />
