changed. Clean or change airway adapter if mucus or moisture is
seen. If the adapter is clean, perform a Zero calibration process. If
problem persists contact Digicare.
Zero Error -
Indicates the Zero calibration process was not successful. Clean
or change the airway adapter. Disconnect and reconnect the
MainFlow™ CO2 sensor in the LifeWindow Lite connector.
Perform a Zero calibration process. If problem persists contact
Digicare.
4 – CO2 SENSOR ACCURACY CHECK
•
The MainFlow™ CO2 sensor is a rugged, solid-state, mainstream sensor. It is factory
calibrated and does not require further calibration. The only calibration required is the Zero
Calibration , witch does not require any special setup, as explained before.
• In applications where it is mandatory to perform a routine Accuracy check, the MainFlow™
CO2 Mainstream sensor shall be compared against calibration gas every 12 months. Contact
Digicare Biomedical Technology for more information.
SECTION 6.2 – SIDESTREAM CO2 MONITORING
A. PRINCIPLE OF OPERATION
The LifeWindow™ Lite LW8 MicroFlow™ Sidestream CO2 module is specifically designed for
sidestream measurement of CO2 and Respiratory Rate, using sophisticated infrared absorption
spectroscopy. MicroFlow™ Sidestream is a sidestream sampling system with a 50 ml/ minute
low sampling rate that is used to measure the CO2 of non-intubated and intubated patients.
Because of its unique design, response is fast and there is less chance of erroneous, artifact
data. The analyzer portion of the sensor cannot be contaminated with patient secretions,
therefore maintenance requirements and overall cost-of-ownership are minimized.
The exclusive Digicare Biomedical Technology family of sidestream sampling and on-airway
adapter kits are easy to use and durable enough even for long-term ventilator patients. Yet, they
are inexpensive and disposable.
The LifeWindow™ Lite LW8 MicroFlow™ Sidestream CO2 module can be installed built-in or
used as an external module interchangeable with the MainFlow™ CO2 Mainstream Sensor
making it easy for you to configure your patient monitoring systems with state-of-the-art CO2
monitoring technology that is affordable and easy to use.
B. INDICATIONS FOR USE
• The intended use of the MicroFlow™ Sidestream CO2 module is to provide carbon dioxide
monitoring to a during anesthesia / recovery, in the intensive care unit (ICU), and in
emergency Medicine/Transport or Respiratory care.
WARNINGS
• Explosion Hazard: DO NOT use in the presence of flammable anesthetics. Use of the MicroFlow™
sidestream CO2 Module in such environment may present an explosion hazard.
• Electrical Shock Hazard: Always disconnect the MicroFlow™ CO2 Sidestream Module before cleaning.
Do NOT use if it appears to have been damaged. Refer servicing to qualified service personnel.
• Follow precautions for electrostatic discharge (ESD) and electromagnetic interference (EMI) to and from
