should appear in yellow beneath the top channel ECG lead – replacing the
impedance respiration parameter box and waveform area.
2. Select the proper Oridion CapnoLine® or FilterLine® single-use sampling
line based on clinical guidelines and hospital standard of care.
3. Open the cover labeled Microstream® ETCO
2
on the PPM3 left side.
4. Place the orange or yellow threaded connector of the sampling line into
the CO
2
input port beneath the opened cover.
a. Gently turn the connector clockwise into the CO
2
input port until a
secure connection is achieved. DO NOT OVER TIGHTEN. Over
tightening may warp the connector such that ventilation or the CO
2
measurement may be compromised. This assures that there is no
leakage of gases during measurement at the connection point and that
measurement accuracy is not compromised.
b. When the connector is secure, the CO
2
pump should start and the
"CO2 Warming Up" message will briefly appear.
5. Securely connect all components and check connections for leaks
according to standard clinical procedures.
6. Connect the patient applied end of the sampling line to the patient as per
instructions included with the CapnoLine ® or FilterLine® packaging.
7. The CO
2
waveform and numeric parameter values should appear within
approximately 10 seconds.
7.3. Checking the CO
2
Signal
When you have connected the patient following the steps listed above, you should
be able to see a CO
2
waveform on the PPM3 display as shown below. The PPM3
should also display values for the patient's end-tidal carbon dioxide (ETCO
2
),
fractional inspired carbon dioxide (FICO
2
), respiration rate from CO
2
(RRc),
Integrated Pulmonary Index (IPI), and alarm limit settings. The infrared light
source used in the Microstream® module generates only the specific wavelengths
characteristic of the CO
2
absorption spectrum. Therefore, no compensations are
required when different concentrations of N
2
O, O
2
, anesthetic agents, and water
vapor are present in the patient’s gases.
