8.3. 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), and
alarm limit settings. With either the ISA or IRMA modules there is negligible
impact on CO
2
measurement accuracy in the presence of O
2
or N
2
O as long as the
correct O
2
and/or N
2
O Compensation value has been selected. See Figure 37 as
well as the PPM3 Monitor Settings chapter.
Figure 28. Masimo CO
2
Waveform and Values
To manually test CO
2
monitoring alarm functionality on a daily basis, you may
use the following approach. First, either connect the patient to the Nightingale
PPM3 using the above procedure or continue as follows with a patient who is
already being monitored. Then, enable the alarms ETCO
2
, RRc, and FICO
2
.
Next, lower the ETCO
2
upper alarm limit setting below its current value. Verify
that "ETCO
2
< [upper limit]" annunciates as a medium grade alarm. Press the
ALARM SILENCE key, and return the ETCO
2
upper alarm limit to its previous
value. Verify that the alarm is no longer active, and that CO
2
monitoring
continues normally. Repeat this process in turn for the RRc and FICO
2
parameters.
The CO
2
Monitoring settings and specifications for the Nightingale PPM3 may be
found in the PPM3 Monitor Settings and Technical Data chapters. Procedures for
changing configuration settings, such as adjusting alarm limits, changing the
waveform size (amplitude), setting the apnea time, or selection O
2
and/or N
2
O
compensation values may be found in the Working With Menus chapter.
