Using the Capnography Extension (M3014A)

Correlation: The etCO

2

 readings do not always correlate closely with paCO

2

, especially in neonatal 

patients and patients with pulmonary disease, pulmonary embolism or inappropriate ventilation.

Pharmaceuticals in aerosols: Do not measure CO

2

 in the presence of pharmaceuticals in aerosols.

Explosion Hazard: Do not use in the presence of flammable anesthetics, such as a flammable 
anesthetic mixture with air, oxygen or nitrous oxide.Use of the devices in such an environment may 
present an explosion hazard.

Failure of operation: if the measurement extension or a sensor fails to respond as described, do not use 
it until the situation has been corrected by qualified personnel.

 values: Leakages in the breathing system or sampling system may cause the displayed 

etCO

2

 values to be significantly too low. Always connect all components securely and check for leaks 

according to standard clinical procedures. Displacement of the nasal or combined nasal oral cannulas 
can cause lower than actual etCO

2

 readings. Even with combined nasal oral cannulas, the etCO

2

 

readings may be slightly lower than actual in patients breathing through the mouth only.

The M3014A Capnography Extension measures partial pressure of carbon dioxide in a patient’s 
expired gas using the mainstream method or the sidestream method. The mainstream CO

2

 

measurement can be used, with appropriate accessories, with intubated adult, pediatric and neonatal 
patients. The sidestream CO

2

 measurement can be used, with appropriate accessories, with intubated 

and nonintubated adult, pediatric and infant patients. With intubated patients, a sample of the 
respiratory gas is drawn from the patient’s breathing circuit through an airway adapter and a gas 
sampling tube. With non-intubated patients, the gas sample is drawn through a nasal or oral-nasal 
cannula.

Altitude Setting: The monitor is not equipped with automatic barometric pressure compensation. 
Before the CO

2

 measurement is used for the first time, the altitude must be set to the correct value. An 

incorrect altitude setting will result in incorrect CO

2

 readings. The CO

2

 readings will typically deviate 

5% for every 1000m difference.

Electrical Shock Hazard: Do not open the measurement extension. Contact with exposed electrical 
components may cause electrical shock. Always turn off and remove power before cleaning the sensor 
or measurement server. Do not use a damaged sensor or one with exposed electrical contacts. Refer 
servicing to qualified service personnel.

Use the M3014A measurement extension with Philips approved accessories only. Refer to the 
instructions for use provided with the accessory.

Attach the sensor connector to the CO

2

 connector on the measurement extension.

Wait 2 minutes, allowing the sensor to reach its operating temperature and a stable thermal 
condition.
