X Series Monitoring Functions
9650-001355-01 Rev. M X Series Operator’s Guide 3-3
Capnography (CO
2
)
CO
2
monitoring measures the CO
2
concentration in a patient’s exhaled breath (End Tidal
Carbon Dioxide --EtCO
2
). CO
2
monitoring can also measure a patient’s breath rate and the
CO
2
concentration in the gases supplied to intubated patients (Fractional Inspired Carbon
Dioxide -- FiCO
2
). Since FiCO
2
represents the amount of CO
2
present during inhalation, it also
serves as an indicator for rebreathing in non-intubated patients. CO
2
monitoring can be used for
both intubated and non-intubated patients.
The EtCO
2
, breath rate, and FiCO
2
measurements appear in a labeled ( EtCO2 ) numeric
display. The EtCO
2
and FiCO
2
measurements can appear as values given in millimeters of
mercury (mmHg). You can also specify that the X Series unit display a CO
2
capnogram in the
waveform trace display area.
Pulse Oximetry (SpO
2
)
Pulse Oximetry monitoring measures the oxygen saturation (SpO
2
) of arterial blood at a
peripheral site such as a finger or toe. If the optional features SpCO (carboxhemoglobin
saturation) and SpMet (methemoglobin saturation) or SpHb (total hemoglobin), SpOC (oxygen
content), PVI (pleth variability index) and PI (perfusion index) are installed, the X Series unit
also monitors these parameters.
SpO
2
monitoring determines the ratio of oxygenated hemoglobin to total hemoglobin in arterial
blood and displays this ratio as percent SpO
2
in a labeled (
SpO2
) numeric display. If the
optional features SpCO and SpMet or SpHB, SpOC, PVI and PI are installed, these values
alternate and display under the SpO
2
display. You can also specify that the X Series unit display
an SpO
2
plethysmograph in the waveform trace display area.
