The device is intended to be re-usable. Should the device or accessories come
in contact with patient bodily fluids, either dispose of the device or clean with
a soft cloth dampened with 70% isopropyl alcohol solution in water and allow
the components to air-dry before re-use .
The device and accessories are not intended to transport or store any medi-
cines, body liquids or other substances that can be administered or removed
from the body, and, do not contain any latex, human blood derivatives, phtha-
lates, carcinogens or other reproductive toxics.
Calibrate the device with 100% oxygen before using each day or after 8 hours
of continuous use. In the event the device fails to calibrate or if the reading
becomes, do not attempt to use the device. Contact the manufacturer for
assistance.
Do not operate the analyzer near equipment capable of emitting high levels of
electromagnetic radiation as the reading may become unstable.
In order to obtain optimum performance, the operation of the device must be
performed in accordance with these Instructions for Use. Maintenance should
be performed only by trained personnel authorized by the manufacturer.
Additional operating pointers are provided in Section 3.
1.2 Intended Use
The AII 2000 Series Oxygen Analyzers & Monitors are intended to measure
and display the concentration of oxygen in breathing gas mixtures. The in-
tended use is only to verify, spot check or continuously monitor, oxygen con-
centrations in circumstances where the oxygen concentration is controlled and
set by other medical device such as oxygen/air blenders, flow meters or other
control device found in the following medical applications:
Anesthesia (refer to Section 5.2)
Respiratory Therapy – Ventilators, Respirators
Neonatal & Pediatric Incubators & Hoods
Oxygen Therapy - Intensive Care
Spot Checking Concentrator

1.3 Device Description
The AII 2000 Series Oxygen Analyzers and Monitor can be positioned on a
table top or pole (tripod wire stand and V-mount dovetail attachments are
mounted on the back of the device) and are readily portable from one location
to another. They provide continuous, fast, reliable and accurate oxygen meas-
urements of up to respiratory care systems.
The devices utilize an electrochemical galvanic fuel cell type oxygen sensor of
the type that is extensively used to measure oxygen concentrations from 0%
to 100% in gas streams. Oxygen, the fuel for this electrochemical transducer,
diffusing into the sensor through a gas permeable membrane reacts chemi-
cally at the sensing electrode to produce an electrical current output propor-
tional to the oxygen concentration in the gas phase. The sensor has an abso-
lute zero meaning that when no oxygen is present to be chemically reacted
the LCD displays 00.0 oxygen.
The sensor’s signal output is linear over the entire range, remains virtually
constant over the specified useful life and drops off sharply at the end. The
sensor itself requires no maintenance and is simply replaced at the end of its
useful life like a battery. Inasmuch as the sensor is a transducer in its own
right, its expected life is not affected by whether the analyzer is ON or OFF.
A battery powered state-of-the-art micro-processor converts the sensor’s sig-
nal output representing the partial pressure of oxygen in the gas stream being
analyzed. The resulting oxygen reading is displayed by a large easy to read
backlit liquid crystal display (LCD) that has a resolution of 0.1% oxygen. The
microprocessor is controlled from a keypad and provides features like system
diagnostics, warning indicators, controls and an alarm capability for continu-
ous monitoring that enhance both safety and effectiveness.
Prior to shipment, every device is thoroughly tested at the factory and docu-
mented in the form of a Quality Control Certification that is included in the
Instructions for Use supplied with every device.
The manufacturer’s contact information and serial number of this device can
be found above the battery compartment cover on the rear of the device and
in Section 2 Quality Control Certification.
In conclusion, Analytical Industries Inc. appreciates the opportunity to supply
this device and anticipates many years of useful service.
