DO NOT use ethylene oxide sterilization.
DO NOT immerse the sensor in any cleaning solution, autoclave or expose the sensor to
high temperatures.
Dropping or severely jarring the sensor after calibration may shift the calibration point
◆
enough to require recalibration.
CAUTIONS
Indicates a potentially hazardous situation, if not avoided, could result in minor or moderate
injury and property damage.
Never install the sensor in a location that will expose the sensor to patient exhalation or
◆
secretions.
Only use Maxtec approved accessories and replacement parts. Failure to do so may seriously
◆
impair the MaxVenturi's performance. Repair or alteration of the MaxVenturi beyond the
scope of the maintenance instructions or by anyone other than authorized Maxtec service
personnel could cause the product to fail to perform as designed.
Use of the MaxVenturi near devices that generate strong electrical fields may cause erratic
◆
readings. In the event of exposure to an ELECTROMAGNETIC DISTURBANCE the analyzer may
display an E02 error message. If this occurs, refer to Section 4.0 for instructions to resolve
the problem.
This device has a visual low-battery alarm but no audible alarm.
◆
Calibrate the MaxVenturi weekly when in operation or if environmental conditions change
◆
significantly, i.e., Temperature, Humidity, Barometric Pressure. (refer to Calibration sections
of this manual).
The device will assume a percent oxygen concentration when calibrating. Be sure to apply
◆
100% oxygen or room air concentration to the device during calibration or the device will not
calibrate correctly. (See section 2.2)
DO NOT immerse the device in any cleaning solution, autoclave or expose the device to
high temperatures.
Use with any other patient interface system may result in false readings from the flow meter.
◆
The MaxVenturi is not intended for steam, ethylene oxide or radiation sterilization.
◆
DO NOT clean with ethanol or acetone.
After cleaning, and before use on a patient, attach the device to an oxygen supply and allow
◆
the device to run at high flow for several minutes to allow any cleaning fluids or vapors to
evaporate and be flushed out.
The device can flow excess oxygen out the entrainment port if the oxygen control knob is
◆
turned up too high. This can lead to a minor drop in total air flow to the patient and excess
oxygen entering the room environment.
Federal Law (USA) restricts this device to sale by or on the order of a physician.
