End-Tidal Carbon Dioxide
(EtCO
2
)
Product Description
R Series
®
units equipped with software revision 5.00 or higher support the End Tidal Carbon
Dioxide (EtCO
2
) monitoring option for the continuous measurement of respiratory carbon
dioxide (CO
2
) and respiration rate.
For R Series BLS/Plus models, the EtCO
2
option can only be used while the unit is in Manual
mode.
The EtCO
2
option uses a unique, mainstream, solid-state, infrared sensor called the
CAPNOSTAT
®
5 Mainstream CO
2
Sensor. The CAPNOSTAT 5 CO
2
sensor is attached to an
airway adapter that connects to an endotracheal (ET) tube or other airway and measures gases
flowing through these breathing circuit components. A disposable mouthpiece may be
connected to the adapter for monitoring non-intubated patients. A CAPNO
2
mask™ is also
available for use with non-intubated patients. This option provides for O
2
delivery while
monitoring expired CO
2
.
In this system, the CO
2
sensor generates infrared light and beams it through the airway adapter
or sample cell to a detector on the opposite side. CO
2
from the patient, flowing through the
mainstream airway adapter or sample cell, absorbs some of this infrared energy. The R Series
unit determines CO
2
concentration in the breathing gases by measuring the amount of light
absorbed by gases flowing through the airway or sample cell.
The R Series unit displays EtCO
2
(the concentration of carbon dioxide detected at the end of
each exhalation) as a numerical value in millimeters of mercury (mmHg), percent (%), or
kilopascals (kPa). In addition, the unit can display a capnogram. This capnogram is a valuable
clinical tool that can be used to assess patient airway integrity and proper endotracheal (ET)
tube placement. The unit calculates respiration rate by measuring the time interval between
detected peaks of the CO
2
waveform. The technology differentiates between waveforms caused
by breathing and those caused by cardiogenic oscillations and artifact.
