Intended Use & Indications for Use
The intended use of the EtCO2 sensor is to provide carbon dioxide
monitoring to a host monitoring system during anesthesia/
recovery in the Intensive Care Unit (ICU) and in Emergency
Medicine/Transport or Respiratory Care.
Measurement Principle
The EtCO2 sensor uses an infrared absorption (IR) technique
for monitoring CO2. The principle is based on the fact that CO2
molecules absorb infrared light energy at specific wavelengths
with the amount of energy absorbed being directly related to
the CO2 concentration. When the IR light beam is passed through
a gas sample containing CO2 the electronic signal from the
photodetector can determine the levels of CO2.
Storage & Handling
When not in use, sensors should be loosely coiled and stored at
room temperature. Don’t wrap sensors around equipment cases to
avoid damaging internal wires.
