1.4 Applications
The MX300-I Portable oxygen analyzer is intended to continuously
measure and display the concentration of oxygen in a gas mixtures used
in medical applications such as Anesthesia, Respiratory therapy and is
intended for adult, pediatric and Neonatal populations.
The instruments may be used in verifying oxygen concentrations in
gas mixtures used in:
• Anesthesia
• Respiratory Therapy
• Neonatal Care
1.5 Theory of Operation
The MX300-I monitor can be divided into two major functional
groups:
• R17MED Oxygen Sensor
• Signal Processing
The analyzer uses Teledyne Analytical Instruments Patented
R17MED oxygen sensor. The millovolt output signal from the sensor is
fed into the electronic signal processor, where it is used to calculate the
oxygen gas concentration and display it on the LCD screen. The data
from the sensor is compared to the alarm values set by the user, and
activates the audible and visual alarms if the oxygen level exceeds those
values. A unique sensor fail/disconnect alarm is incorporated in the
MX300-I to warn the user of a sensor problem. The√ SENSOR indicator
