Intended Use & Indications for Use
The intended use of the EtCO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 EtCOsensor uses an infrared absorption (IR) technique
for monitoring CO. The principle is based on the fact that CO
molecules absorb infrared light energy at specic wavelengths
with the amount of energy absorbed being directly related to
the COconcentration. When the IR light beam is passed through
a gas sample containing COthe electronic signal from the
photodetector can determine the levels of CO.
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.

Operating Conditions
• Ambient temperature: 0°C to +40°C
• Relative humidity: 15% to 85%
• Atmospheric pressure: 86 kpa ~106 kpa
Storage & Packaging
Each sensor is individually packaged.
Sensors must be stored in their original packaging and within the
storage conditions to maximize the storage life.
Storage conditions are as follows:
• Ambient temperature: -10°C to +40°C
• Relative humidity: 15% to 85%
• Atmospheric pressure: 86 kpa ~106 kpa
Shelf Life
5 years.
Installation & Use
• Mainstream EtCO2Sensor

4 5
- Insert the EtCOSensor connector into the receptacle of the
host monitor.
- Choose the appropriate airway adapter and connect it to the
sensor head. The airway adapter clicks into place when seated
correctly (See gure 1).
- Set the sensor to zero.
- Install the airway adapter at the proximal end of the circuit
between the elbow and the ventilator Y-section (see gure 2).
Figure 1 Figure 2
• External Sidestream EtCO2Sensor
- Insert the EtCOSensor connector into the receptacle of the
host monitor.

4 5
- Connect the cannula, airway adapter, or sample line as
appropriate to the sensor. It will click into place when seated
correctly.
- Set the sensor to zero.
- For intubated patients requiring an airway adapter: Install the
airway adapter at the proximal end of the circuit between the
elbow and the ventilator Y- section (see figure 3).
- For intubated patients with an integrated airway adapter in
the breathing circuit: Connect the male luer connector on the
straight sample line to the female port on the airway adapter
(see gure 4).
Figure 3 Figure 4
- For non-intubated patients: Place the nasal cannula on the
patient (see gure 5).

Figure 5 Figure 6
- For patients prone to mouth breathing use an oral-nasal
cannula. For nasal or oral-nasal cannulas with oxygen delivery:
place the cannula on the patient as shown and then attach the
oxygen supply tubing to the oxygen delivery system and set the
prescribed oxygen ow (see gure 6).

Cleaning and Disinfecting
• Unplug the sensor before cleaning or disinfecting.
• Dip clean the sensor part (not the connector) in a mild
detergent solution or a 70% isopropyl alcohol solution. If low-
level disinfection is required use a 1:10 bleach/water solution.
• Rinse the sensor part (not the connector) in water, wipe it with a
dry cloth and leave to dry completely.
Caution
Do not sterilize by irradiation steam, or ethylene oxide.
Warranty & Liability
Orantech oers 12 months warranty against defects in material or
workmanship from the date of purchase. But does not include the
damage or breakage due to the abusive use or negligent care of
the sensors.
Orantech reserves the right to perform warranty service at its
own facility. We guarantee that the products conform to the
specications of the safety and performance standards currently in

force and applicable to it.
Warning
• Before using the sensor conrm that the reading is set to zero. If
a non-zero reading is showing manually set to zero. Non-zeroing
may result in incorrect readings.
• Sensors are designed for use with specic monitors.
• The operator is responsible for checking the compatibility of the
monitor and sensor before use.
• Incompatible components can result in degraded accuracy and
performance.
• Consult the operation instructions for the equipment concerned
and the related accessories before operating equipment to
ensure their compatibility.
• Portable and mobile RF communications equipment can aect
the equipment.
• Do not use the sensor during MRI scanning. Conducted
current may cause burns on the patient. The sensor may aect
the MRI image, and the MRI unit may aect the accuracy of
measurements.
• Do not immerse sensor or sensor connector ends in cleaning
solution(s).
