1.0 INTRODUCTION
The MaxBlend 2 is a compact air/oxygen gas mixing device which incorporates the use of a
battery powered oxygen monitor. The gas mixing device (blender) provides precise mixing of
medical-grade air and oxygen, while the monitor measures the selected oxygen concentra-
tions from the blender's gas flow and displays these measured concentrations on a digital
display. The monitor provides high and low alarm limits which, when exceeded, cause an
audible and visual alarm.
1.1 Indication for Use
The MaxBlend 2 is designed to provide a continuous air/oxygen gas mixture and to continu-
ously monitor the concentration of oxygen being delivered to infant, pediatric, and adult
patients. It is a restricted medical device intended for use by qualified, trained personnel,
under the direction of a physician, in professional healthcare settings, i.e., hospital, subacute,
and nursing-care facilities where the delivery and monitoring of air/oxygen mixtures is
required. This is not intended as a life supporting device.

1.2 MAX-550E Oxygen Sensor
The MAX-550E is a galvanic, partial pressure sensor that is specific to oxygen. It consists of two
electrodes (a cathode and an anode), a teflon membrane and an electrolyte. Oxygen diffuses
through the teflon membrane and immediately reacts electrochemically at a gold cathode.
Concurrently, oxidation occurs electrochemically at a lead anode, generating an electrical cur-
rent and providing a voltage output. Electrodes are immersed in a unique gelled weak acid
electrolyte, which is responsible for the sensor's long life and motion insensitive characteristic.
Since the sensor is specific to oxygen, the current generated is proportional to the amount of
oxygen present in the sample gas. When no oxygen is present, there is no electrochemical
reaction, and therefore, negligible current is produced. In this sense, the sensor is self-zeroing.
