46. with a power outlet the supply pressure at the flowmeter will decrease during periods of high flow from the power outlet This will cause a decrease in flowmeter accuracy The actual flow from the flowmeter outlet will be lower than that indicated For example with 150 l min flowing from the power outlet the supply pres sure drops from 50 psi to 46 psi and the actual flow from the flowmeter is then lower than indicated by up to 20 Do not use a flowmeter with any cracked or damaged plastic components gas leaks loose fittings or knobs or any missing components Supply gas pressure can cause parts to be expelled and injury may occur Do not connect flowmeter to supply pressures in excess of 72 5 psi 5 bar Excess supply pressure can cause parts to be expelled and injury may occur The flowmeter is only intended for the gas specified on flowmeter label Do not use the flowmeter with any other gases Inaccurate flow indications and patient injury may result The flowmeter is calibrated using the gas supply pres sure and temperature shown on the flowmeter label Varying pressure temperature or both will reduce accu racy Power outlet models ONLY Connect the high pressure hose to the therapy device before making the connection to the flowmeter power outlet 6700 0094 000 RevD 10 2007 After patient use oxygen therapy equipment may be con taminated Handle in accordance with your hospital s infection control policy
